Consultations With Other Agencies DOE consulted with the Federal Trade Commission (FTC) staff concerning the Electrolux petition for waiver. The FTC staff did not have any objections to granting a waiver to Electrolux. mstockstill on DSKH9S0YB1PROD with NOTICES FR 10425); May 5, 2009 (74 FR 20695); December 15, 2009 (74 FR 66338), March 11, 2010 (75 FR 11530), April 29, 2010 (75 FR 22584); August 19, 2010 (75 FR 51264); March 18, 2010 (75 FR 13120), August 3, 2010 (75 FR 45623); and June 7, 2010 (75 FR 32175), respectively. The approved alternate test procedure simulates the energy used by the adaptive heaters in a typical consumer household, as explained in the respective decisions and orders referenced above. As DOE has stated in the past, it is in the public interest to have similar products tested and rated for energy consumption on a comparable basis. Since the publication of the December notice, DOE issued an interim final rule that prescribes a particular procedure to address the type of system employed by the Electrolux products at issue. See 75 FR 78810 (December 16, 2010). This procedure would apply to those products manufactured starting in 2014. 6.2.3 Variable anti-sweat heater control test. The standard cycle energy consumption of an electric refrigerator-freezer with a variable anti-sweat heater control in the on position (Eon), expressed in kilowatt-hours per day, shall be calculated equivalent to: EON = E + (Correction Factor) where E is determined by sections 6.2.1.1, 6.2.1.2, 6.2.2.1, or 6.2.2.2, whichever is appropriate, with the anti-sweat heater switch in the off position. Correction Factor = (Anti-sweat Heater Power × System-loss Factor) × (24 hrs/1 day) × (1 kW/1000 W) Where: Anti-sweat Heater Power = A1 * (Heater Watts at 5%RH) + A2 * (Heater Watts at 15%RH) + A3 * (Heater Watts at 25%RH) + A4 * (Heater Watts at 35%RH) + A5 * (Heater Watts at 45%RH) + A6 * (Heater Watts at 55%RH) + A7 * (Heater Watts at 65%RH) + A8 * (Heater Watts at 75%RH) + A9 * (Heater Watts at 85%RH) + A10 * (Heater Watts at 95%RH) where A1–A10 are defined in the following table: IV. Conclusion After careful consideration of all the material that was submitted by Electrolux and consultation with the FTC staff, it is ordered that: (1) The petition for waiver submitted by the Electrolux Home Products, Inc. (Case No. RF–017) is hereby granted as set forth in the paragraphs below. (2) Electrolux shall not be required to test or rate the following Electrolux models: EI27BS**** FGUN26**** CFD26***on the basis of the current test procedures contained in 10 CFR part 430, subpart B, appendix A1. Instead, it shall be required to test and rate such products according to the alternate test procedure as set forth in paragraph (3) below: (3) Electrolux shall be required to test the products listed in paragraph (2) above according to the test procedures for electric refrigerator-freezers prescribed by DOE at 10 CFR part 430, appendix A1, except that, for the Electrolux products listed in paragraph (2) only: (A) The following definition is added at the end of Section 1: 1.13 Variable anti-sweat heater control means an anti-sweat heater where power supplied to the device is determined by an operating condition variable(s) and/or ambient condition variable(s). (B) Section 2.2 is revised to read as follows: VerDate Mar<15>2010 16:52 Apr 05, 2011 Jkt 223001 Operational conditions. The electric refrigerator or electric refrigerator-freezer shall be installed and its operating conditions maintained in accordance with HRF–1–1979, section 7.2 through section 7.4.3.3, except that the vertical ambient temperature gradient at locations 10 inches (25.4 cm) out from the centers of the two sides of the unit being tested is to be maintained during the test. Unless shields or baffles obstruct the area, the gradient is to be maintained from 2 inches (5.1 cm) above the floor or supporting platform to a height 1 foot (30.5 cm) above the unit under test. Defrost controls are to be operative. The anti-sweat heater switch is to be off during one test and on during the second test. In the case of an electric refrigerator-freezer equipped with variable anti-sweat heater control, the result of the second test will be derived by performing the calculation described in 6.2.3. Other exceptions are noted in 2.3, 2.4, and 5.1 below. (C) New section 6.2.3 is inserted after section 6.2.2.2.

Electrolux may make representations about the energy use of its adaptive control anti-sweat heater refrigerator-freezer products for PO 00000 Frm 00050 Fmt 4703 Sfmt 4703 compliance, marketing, or other purposes only to the extent that such products have been tested in accordance with the provisions outlined above and such representations fairly disclose the results of such testing. (5) This waiver shall remain in effect consistent with the provisions of 10 CFR 430.27(m). (6) This waiver is issued on the condition that the statements, representations, and documentary materials provided by the petitioner are valid. DOE may revoke or modify this waiver at any time if it determines the factual basis underlying the petition for waiver is incorrect, or the results from the alternate test procedure are unrepresentative of the basic models’ true energy consumption characteristics. (7) Grant of this waiver does not release a petitioner from the certification requirements set forth at 10 CFR 430.62. Issued in Washington, DC, on March 30, 2011.

Background and Authority Title III of the Energy Policy and Conservation Act (EPCA) sets forth a variety of provisions concerning energy efficiency, including Part B of Title III, which establishes the ‘‘Energy Conservation Program for Consumer Products Other Than Automobiles.’’ (42 U.S.C. 6291–6309) Part C of Title III provides for a similar energy efficiency program titled ‘‘Certain Industrial Equipment,’’ which includes commercial air conditioning equipment, package boilers, water heaters, and other types of commercial equipment.1 (42 U.S.C. 6311–6317) Today’s notice involves commercial equipment under Part C. Part C specifically includes definitions (42 U.S.C. 6311), test procedures (42 U.S.C. 6314), labeling provisions (42 U.S.C. 6315), energy conservation standards (42 U.S.C 6313), and the authority to require information and reports from manufacturers (42 U.S.C. 6316). With respect to test procedures, Part C authorizes the Secretary of Energy (the Secretary) to prescribe test procedures that are reasonably designed to produce results that measure energy efficiency, energy use, and estimated annual operating costs, and that are not unduly burdensome to conduct. (42 U.S.C. 6314(a)(2)) For commercial package airconditioning and heating equipment, EPCA provides that ‘‘the test procedures shall be those generally accepted industry testing procedures or rating procedures developed or recognized by the Air-Conditioning and Refrigeration Institute [ARI] or by the American Society of Heating, Refrigerating and Air-Conditioning Engineers [ASHRAE], as referenced in ASHRAE/IES Standard 90.1 and in effect on June 30, 1992.’’ (42 U.S.C. 6314(a)(4)(A)) Under 42 U.S.C. 6314(a)(4)(B), the statute further directs the Secretary to amend the test procedure for a covered commercial product if the industry test procedure is amended, unless the Secretary determines, by rule and based on clear and convincing evidence, that such a modified test procedure does not meet the statutory criteria set forth in 42 U.S.C. 6314(a)(2) and (3). On December 8, 2006, DOE published a final rule adopting test procedures for commercial package air-conditioning 1 For editorial reasons, upon codification in the U.S. Code, Part C was re-designated Part A–1. PO 00000 Frm 00051 Fmt 4703 Sfmt 4703 19079 and heating equipment, effective January 8, 2007. 71 FR 71340. Table 1 to Title 10 of the Code of Federal Regulations (10 CFR) 431.96 directs manufacturers of commercial package air conditioning and heating equipment to use the appropriate procedure when measuring energy efficiency of those products. The test procedures applicable to small commercial packaged air conditioning and heating water-source heat pumps, with capacities less than 135,000 Btu/h, are those included in ISO Standard 13256– 1 (1998). The capacities of Mitsubishi’s WR2 and WY CITY MULTI water-source products covered by this petition fall in that range. For commercial package airsource equipment with capacities between 65,000 and 760,000 Btu/h, ARI Standard 340/360–2004 is the applicable test procedure under 10 CFR 431.96. The capacities of Mitsubishi’s S&L Class CITY MULTI commercial products fall in that range. DOE’s regulations for covered products permit a person to seek a waiver from the test procedure requirements for covered commercial equipment if at least one of the following conditions is met: (1) The petitioner’s basic model contains one or more design characteristics that prevent testing according to the prescribed test procedures; or (2) the prescribed test procedures may evaluate the basic model in a manner so unrepresentative of its true energy consumption as to provide materially inaccurate comparative data. 10 CFR 431.401(a)(1). Petitioners must include in their petition any alternate test procedures known to the petitioner to evaluate the basic model in a manner representative of its energy consumption. 10 CFR 431.401(b)(1)(iii). The Assistant Secretary for Energy Efficiency and Renewable Energy (Assistant Secretary) may grant a waiver subject to conditions, including adherence to alternate test procedures. 10 CFR 431.401(f)(4). Waivers remain in effect pursuant to the provisions of 10 CFR 431.401(g). The waiver process also permits parties submitting a petition for waiver to file an application for interim waiver of the applicable test procedure requirements. 10 CFR 431.401(a)(2). The Assistant Secretary will grant an interim waiver request if it is determined that the applicant will experience economic hardship if the application for interim waiver is denied, if it appears likely that the petition for waiver will be granted, and/or the Assistant Secretary determines that it would be desirable for public policy reasons to grant immediate relief pending a E:\FR\FM\06APN1.SGM 06APN1 19080 Federal Register / Vol. 76, No. 66 / Wednesday, April 6, 2011 / Notices mstockstill on DSKH9S0YB1PROD with NOTICES determination on the petition for waiver. 10 CFR 431.401(e)(3). An interim waiver remains in effect for 180 days or until DOE issues its determination on the petition for waiver, whichever occurs first. It may be extended by DOE for an additional 180 days. 10 CFR 431.401(e)(4). II. Petition for Waiver On February 18, 2011, Mitsubishi filed an application for interim waiver and a petition for waiver from the test procedures under 10 CFR 431.96 that apply to commercial package air and water-source air conditioners and heat pumps. Mitsubishi’s petition requests a waiver from the applicable test procedures for its additional indoor models to be used with the WR2 and WY Series and S&L Class CITY MULTI products. On December 15, 2009, DOE granted Mitsubishi waivers from the DOE commercial air conditioner and heat pump test procedures for Mitsubishi’s WR2 and WY Series products and the S&L Class products. 74 FR 66311, 66315. Mitsubishi’s February 18, 2011 petition lists additional models of indoor units for these multi-split systems. These include models in existing model families that have capacities not previously offered, as well as new indoor model families to be used with these systems. These additional indoor models face the same testing challenges as the models already covered by the WR2 and WY Series Waiver and the S&L Class Waiver. Mitsubishi seeks a waiver from the applicable test procedures under 10 CFR 431.96 on the grounds that its WR2, WY and S&L Class multi-split heat pumps contain design characteristics that prevent testing according to the current DOE test procedures. DOE granted the WR2 and WY Series products a waiver because the basic model of these products contains one or more design characteristics that prevent testing of the basic model according to the prescribed test procedures. DOE made the same finding with respect to the S&L Class products, stating that the existing testing facilities have limited ability to test multiple indoor units at one time, and that the number of possible combinations of indoor and outdoor units is impractical to test, and thus granted Mitsubishi’s requested waiver. The additional indoor models that are the subject of this petition would be used just as the products covered by the WR2 and WY Series Waiver and the S&L Class Waiver, and thus present exactly the same testing challenges. As DOE found in its grant of the WR2 and WY Series Waiver and the S&L VerDate Mar<15>2010 16:52 Apr 05, 2011 Jkt 223001 Class Waiver, indoor models are not the primary efficiency drivers for these systems—the primary efficiency drivers are the outdoor units. Mitsubishi is not proposing to add new outdoor units to the WR2 and WY Series Waiver and S&L Class Waiver. The indoor units described above will be combined with the same outdoor unit models covered by the prior waivers to create multi-split systems. III. Application for Interim Waiver On February 18, 2011, Mitsubishi also submitted an application for an interim waiver from the test procedures at 10 CFR 431.96 for its specified WR2, WY, and S&L equipment. DOE determined that Mitsubishi’s application for interim waiver does not provide sufficient market, equipment price, shipments, and other manufacturer impact information to permit DOE to evaluate the economic hardship Mitsubishi might experience absent a favorable determination on its application for an interim waiver. DOE understands, however, that if it did not issue an interim waiver, Mitsubishi’s products would not be tested and rated for energy consumption in the same manner as similar products for which DOE previously granted waivers. Furthermore, DOE has determined that it appears likely that Mitsubishi’s petition for waiver will be granted and that is desirable for public policy reasons to grant Mitsubishi immediate relief pending a determination on the petition for waiver. DOE believes that it is likely Mitsubishi’s petition for waiver for the new WR2, WY and S&L Class multi-split models will be granted because DOE has previously granted a number of waivers for similar product designs. The two principal reasons supporting the grant of the previous waivers also apply to Mitsubishi’s WR2, WY and S&L Class products: (1) Test laboratories cannot test products with so many indoor units; and (2) it is impractical to test so many combinations of indoor units with each outdoor unit. In addition, DOE believes that similar products should be tested and rated for energy consumption on a comparable basis. For these same reasons, DOE also determined that it is desirable for public policy reasons to grant immediate relief pending a determination on the petition for waiver. Therefore, it is ordered that: The application for interim waiver filed by Mitsubishi is hereby granted for Mitsubishi’s WR2, WY and S&L Class multi-split heat pumps, subject to the specifications and conditions below. PO 00000 Frm 00052 Fmt 4703 Sfmt 4703 1. Mitsubishi shall not be required to test or rate its WR2, WY and S&L Class commercial multi-split products on the basis of the existing test procedures under 10 CFR 431.96, which incorporates by reference ARI 340/360– 2004 (S&L Class) and ISO Standard 13256–1 (1998) (WR2 and WY classes). 2. Mitsubishi shall be required to test and rate its WR2, WY and S&L Class commercial multi-split products according to the alternate test procedure as set forth in section IV(3), ‘‘Alternate test procedure.’’ The interim waiver applies to the following indoor units: • PCFY—Series—Ceiling Suspended—with a capacity of 15 MBtu/h • PEFY Series—Ceiling Concealed Ducted (Low Profile)—with a capacity of 15 MBtu/h • PKFY Series—Wall Mounted—with a capacity of 15 MBtu/h • PLFY Series—4-Way Airflow Ceiling Cassette—with a capacity of 15 MBtu/h • The PEFY–AF Series—100% outdoor air ventilation systems (Concealed ducted)—PEFY– AF1200CFM/CFMR**—with a maximum outside air ventilation capability of 1200 CFM • The PVFY Series-Vertical air handler (Concealed ducted)—with capacities of 12/18/24/30/36/42/48/54 MBtu/h • PWFY Series—Commercial Hot Water Heat Pump Indoor Units—with capacities of 36/72 MBtu/h and 36 MBtu/h with booster unit. • PEFY Series—Ceiling Concealed Ducted—with capacities of 06/08/12/15/ 18/24/27/30/36/48 MBtu/h • PLFY Series—2′-by-2′ frame 4-Way Airflow Ceiling Cassette—with capacities of 8/12/15 MBtu/h This interim waiver is issued on the condition that the statements, representations, and documents provided by the petitioner are valid. DOE may revoke or modify this interim waiver at any time if it determines the factual basis underlying the petition for waiver is incorrect or the results from the alternate test procedure are unrepresentative of the basic models’ true energy consumption characteristics. DOE makes decisions on waivers and interim waivers for only those models specifically set out in the petition, not future models that may be manufactured by the petitioner. MEUS may submit a new or amended petition for waiver and request for grant of interim waiver, as appropriate, for additional models of commercial package air conditioners and heat pumps for which it seeks a waiver from the DOE test procedure. In E:\FR\FM\06APN1.SGM 06APN1 Federal Register / Vol. 76, No. 66 / Wednesday, April 6, 2011 / Notices mstockstill on DSKH9S0YB1PROD with NOTICES addition, DOE notes that grant of an interim waiver or waiver does not release a petitioner from the certification requirements set forth at 10 CFR Part 431, Subpart T. IV. Alternate Test Procedure In responses to petitions for waiver from Mitsubishi, DOE specified an alternate test procedure to provide a basis from which Mitsubishi could test and make valid energy efficiency representations for its R410A CITY MULTI products, as well as for its R22 multi-split products. Alternate test procedures related to the Mitsubishi petitions were published in the Federal Register on April 9, 2007. See 72 FR 17528 and 72 FR 17533. The same alternate test procedure was specified in the December 15, 2009 waivers. For reasons similar to those published in these prior notices, DOE believes that an alternate test procedure is appropriate in this instance. We further note that after DOE granted a waiver for Mitsubishi’s multisplit products, ARI formed a committee to discuss testing issues and to develop a testing protocol for variable refrigerant flow systems. The committee has developed a test procedure which has been adopted by AHRI—‘‘ANSI/AHRI 1230—2010: Performance Rating of Variable Refrigerant Flow (VRF) MultiSplit Air-Conditioning and Heat Pump Equipment’’ and incorporated into ASHRAE 90.1—2010. The commercial multisplit waivers that DOE has granted to Mitsubishi and several other manufacturers and the alternate test procedure set forth in those waivers are consistent with AHRI 1230–2010. The waivers use a definition of ‘‘tested combination’’ that is substantially the same as the definition in AHRI 1230– 2010. As a result, DOE is considering prescribing ANSI/AHRI 1230–2010 in the subsequent decision and order as the alternate test procedure for this Mitsubishi waiver. For the interim waiver, however, DOE will continue to require the use of the alternate test procedure prescribed in the past multisplit waivers. Therefore, as a condition for granting this interim waiver to Mitsubishi, DOE is including an alternate test procedure similar to those granted to Mitsubishi in its previous waivers and identical to the ones granted on December 15, 2009. This alternate test procedure will allow Mitsubishi to test and make energy efficiency representations for its WR2, WY and S&L Class products. DOE has applied a similar alternate test procedure to other waivers for similar residential and commercial central air conditioners and heat pumps VerDate Mar<15>2010 16:52 Apr 05, 2011 Jkt 223001 manufactured by Mitsubishi (72 FR 17528, April 9, 2007); Samsung (72 FR 71387, Dec. 17, 2007); Fujitsu (72 FR 71383, Dec. 17, 2007); Daikin (73 FR 39680, July 10, 2008); Daikin (74 FR 15955, April 8, 2009); Daikin (74 FR 16193, April 9, 2009); Daikin (74 FR 16373, April 10, 2009); Mitsubishi (74 FR 66311, 66315, December 15, 2009) and LG (74 FR 66330, December 15, 2009). The alternate test procedure developed in conjunction with the Mitsubishi waiver permits Mitsubishi to designate a ‘‘tested combination’’ for each model of outdoor unit. The indoor units designated as part of the tested combination must meet specific requirements. For example, the tested combination must have from two to eight indoor units so that it can be tested in available test facilities. (The ‘‘tested combination’’ was originally defined to consist of one outdoor unit matched with between 2 and 5 indoor units. The maximum number of indoor units in a tested combination is increased in this instance from 5 to 8 to account for the fact that these largercapacity products can accommodate a greater number of indoor units.) The tested combination must be tested according to the applicable DOE test procedure, as modified by the provisions of the alternate test procedure as set forth below. The alternate test procedure also allows manufacturers of such products to make valid and consistent representations of energy efficiency for their airconditioning and heat pump products. DOE plans to consider inclusion of the following waiver language in the decision and order for Mitsubishi’s WR2, WY and S&L Class commercial multi-split water-source heat pump models: Mitsubishi shall not be required to test or rate its WR2, WY and S&L Class commercial multi-split heat pumps according to the existing test procedures under Table 1 of 10 CFR 431.96, which incorporates by reference the Air-Conditioning and Refrigeration Institute (ARI) Standard 340/360–2004 for the air-source S&L Class products, and ISO Standard 13256–1998 for the water-source WR2 and WY Series products. Mitsubishi will be required, however, to test and rate its WR2, WY and S&L Class commercial multisplit heat pumps covered in this waiver according to the alternate test procedure as set forth below: (A) Mitsubishi shall be required to test the basic models of WR2, WY and S&L Class water and air-source outdoor units and compatible indoor units listed in its petition for waiver dated February 18, 2011, according to the test procedures for commercial central air conditioners and heat pumps prescribed under 10 CFR 431.96, except that Mitsubishi shall test a ‘‘tested PO 00000 Frm 00053 Fmt 4703 Sfmt 4703 19081 combination’’ selected in accordance with the provisions of subparagraph (B). For every other system combination using the same outdoor unit as the tested combination, Mitsubishi shall make representations concerning the WR2, WY and S&L Class equipment covered in this interim waiver according to the provisions of subparagraph (C). (B) Tested combination. The term tested combination means a sample basic model comprised of units that are production units, or are representative of production units, of the basic model being tested. For the purposes of this waiver, the tested combination shall have the following features: (1) The basic model of a variable refrigerant flow system used as a tested combination shall consist of one outdoor unit, with one or more compressors, that is matched with between two and five indoor units. (For systems with nominal cooling capacities greater than 150,000 Btu/h, as many as eight indoor units may be used, so that non-ducted indoor unit combinations can also be tested.) For multi-split systems, each of these indoor units shall be designed for individual operation. (2) The indoor units shall— (i) Represent the highest sales model family or another indoor model family if the highest sales model family does not provide sufficient capacity (see ii); (ii) Together, have a nominal cooling capacity that is between 95% and 105% of the nominal cooling capacity of the outdoor unit; (iii) Not, individually, have a nominal cooling capacity that is greater than 50% of the nominal cooling capacity of the outdoor unit; (iv) Operate at fan speeds that are consistent with the manufacturer’s specifications; and (v) Be subject to the same minimum external static pressure requirement while being configurable to produce the same static pressure at the exit of each outlet plenum when manifolded as per section 2.4.1 of 10 CFR part 430, subpart B, appendix M. (C) Representations. In making representations about the energy efficiency of its WR2, WY and S&L Class variable capacity multi-split heat pump products for compliance, marketing, or other purposes, Mitsubishi must fairly disclose the results of testing under the DOE test procedure in a manner consistent with the provisions outlined below: (1) For WR2, WY and S&L Class combinations tested in accordance with this alternate test procedure, Mitsubishi may make representations based on these test results. (2) For WR2, WY and S&L Class combinations that are not tested, Mitsubishi may make representations of non-tested combinations at the same energy efficiency level as the tested combination. The outdoor unit must be the one used in the tested combination. The representations must be based on the test results for the tested combination. The representations may also be determined by an Alternative Rating Method approved by DOE.

Summary and Request for Comments Through today’s notice, DOE announces receipt of the Mitsubishi petition for waiver from the test procedures applicable to Mitsubishi’s WR2, WY and S&L Class commercial multi-split heat pump products. For the reasons articulated above, DOE also grants Mitsubishi an interim waiver from those procedures. As part of this notice, DOE is publishing Mitsubishi’s petition for waiver in its entirety. The petition contains no confidential information. Furthermore, today’s notice includes an alternate test procedure that Mitsubishi is required to follow as a condition of its interim waiver.

Kathleen Hogan, Deputy Assistant Secretary for Energy Efficiency, Office of Technology Development, Energy Efficiency and Renewable Energy. February 18, 2011 The Honorable Cathy Zoi, Assistant Secretary for Energy Efficiency and Renewable Energy, U.S. Department of Energy, 1000 Independence Ave, SW., Washington, DC 20585–0121 Re: Update to Previously-Granted Test Procedure Waivers for CITY MULTI VRFZ WR2 and WY Series and S&L Class Air Conditioners and Heat Pumps Dear Assistant Secretary Zoi: On December 15, 2009, the Department of Energy (DOE) granted Mitsubishi Electric & Electronics USA, Inc. (MEUS) a waiver from the DOE commercial air conditioner and heat pump test procedures for MEUS’s WR2 and WY Series products 1 and the S&L Class products.2 These products are part of MEUS’s CITY MULTI Variable Refrigerant Flow Zoning (VRFZ) line of multi-split central air conditioners and heat pumps. As explained in MEUS’s petitions for waiver for the WR2 and WY Series and the S&L Class products, these systems cannot be tested according to the prescribed test procedures for commercial products. Pursuant to DOE’s grant of the waivers, MEUS is not required to test or rate the products listed in the waivers based on the currently applicable test procedure. Instead, MEUS is required to test and rate these products according to the alternate test procedure set forth in the waivers. MEUS has now developed additional models of indoor units for these multisplit systems. These include both models in certain existing model families that have capacities not previously offered, as well as new indoor model families to be used with these systems. These additional indoor models face the same testing challenges as the models already covered by the WR2 and WY Series Waiver and the S&L Class Waiver. Specifically, they 1 Energy Conservation Program for Certain Industrial Equipment: Decision and Order Granting a Waiver to Mitsubishi Electric and Electronics USA, Inc.

PO 00000 Frm 00054 Fmt 4703 Sfmt 4703 contain one or more design characteristic that prevents testing according to the test procedures. Therefore, MEUS respectfully requests that DOE update the list of models covered by the applicable test procedure waivers to cover these additional indoor models.3 MEUS simultaneously requests an interim waiver covering systems using these additional indoor models. MEUS frames this request to update the list of models covered by two already-granted waivers pursuant to the requirements for granting new test procedure waivers.4 Given that this request simply addresses the addition of certain new indoor models for MEUS’s WR2 and WY Series and the S&L Class products, and that DOE previously has granted waivers for the outdoor units and other indoor units for these systems, if DOE would prefer to utilize a procedurally simpler approach for updating the covered list of models, MEUS would welcome such an approach. Background On October 30, 2006, MEUS submitted a Petition for Waiver from the test procedures applicable to the watersource WR2 and WY Series of its CITY MULTI VRFZ line of commercial package heat pump equipment. Mitsubishi sought a waiver from the applicable test procedures because the design characteristics of these models prevented testing according to the currently prescribed test procedures. Specifically, these models can connect an outdoor unit to many more indoor units than the test laboratories can physically test at one time, and it is not practical to test all of the potentially available combinations. DOE granted the requested waiver because ‘‘the basic model [of these products] contains one or more design characteristics which * * * prevent testing of the basic model according to the prescribed test procedures.’’ 5 The waiver included an alternate test procedure pursuant to which MEUS must test and rate the products covered by the waiver. On March 28, 2008, MEUS submitted a Petition for Waiver from the test procedures applicable to the S&L Class models from MEUS’s CITY MULTI VRFZ line of commercial package heat pump equipment. MEUS based its request on the fact that the testing laboratories cannot test systems with so many indoor units, and that there are 3 The existing WR2 and WY Series Waiver and S&L Class Waiver would remain in effect until DOE modifies those waivers in accordance with this request. 4 See 10 CFR § 431.401. 5 WR2 and WY Series Waiver at 66313. E:\FR\FM\06APN1.SGM 06APN1 Federal Register / Vol. 76, No. 66 / Wednesday, April 6, 2011 / Notices mstockstill on DSKH9S0YB1PROD with NOTICES too many possible combinations of indoor units with a single outdoor unit to test. DOE agreed with MEUS that the existing testing facilities have limited ability to test multiple indoor units at one time, and that the number of possible combinations of indoor and outdoor units is impractical to test, and thus granted MEUS’s requested waiver.6 DOE approved an alternate test procedure pursuant to which MEUS must test and rate the models covered by the waiver. New Indoor Models Both the WR2 and WY Series Waiver and the S&L Class Waiver covered the following indoor model families: (1) PCFY Series—Ceiling Suspended; (2) PEFY Series—Ceiling Concealed Ducted (Low Profile); (3) PKFY Series—Wall Mounted; and (4) PLFY Series—4-Way Airflow Ceiling Cassette. For each of these indoor model families, MEUS has developed an additional model with a capacity of 15 MBtu/h. At the time MEUS initially filed its petitions for waiver for the WR2 and WY Series and S&L Class products, this capacity product was not available. MEUS has developed this additional capacity product to meet customer demands for specialized applications. When MEUS originally applied for a waiver for its WR2 and WY Series and its S&L Class products, it only included those indoor units that were being produced at that time. MEUS has now developed new indoor model types to expand its CITY MULTI product line to offer consumers a greater variety of available indoor units to suit consumers’ specific needs. MEUS plans to add five new types of indoor unit families to the line-up of indoor units that can be matched with the CITY MULTI outdoor units. The new indoor model families will be: (1) PEFY–AF; (2) PVFY; (3) PWFY; (4) PLFY Series—2′by-2′ frame 4-Way Airflow Ceiling Cassette; and (5) PEFY Series—Ceiling Concealed Ducted. The difference between these new indoor models and the models previously covered by the waivers relates to their application. All of the new models have been developed for specialized applications to meet consumers’ unique demands. MEUS requests that the WR2 and WY Series Waiver and the S&L Class Waiver be updated to cover the following additional indoor units: • PCFY-Series-Ceiling Suspended— with a capacity of 15 MBtu/h • PEFY Series-Ceiling Concealed Ducted (Low Profile)—with a capacity of 15 MBtu/h • PKFY Series-Wall Mounted—with a capacity of 15 MBtu/h • PLFY Series-4-Way Airflow Ceiling Cassette—with a capacity of 15 MBtu/h • The PEFY–AF Series—100% outdoor air ventilation systems (Concealed ducted)—PEFY– AF1200CFM/CFMR**—with a maximum outside air ventilation capability of 1200 CFM • The PVFY Series—Vertical air handler (Concealed ducted)—with capacities of 12/18/24/30/36/42/48/54 MBtu/h • PWFY Series—Commercial Hot Water Heat Pump Indoor Units—with capacities of 36/72 MBtu/h and 36 MBtu/h with booster unit. • PEFY Series—Ceiling Concealed Ducted—with capacities of 06/08/12/15/ 18/24/27/30/36/48 MBtu/h • PLFY Series—2′-by-2′ frame 4-Way Airflow Ceiling Cassette—with capacities of 8/12/15 MBtu/h For DOE’s convenience, MEUS is attaching comprehensive lists of all of the models for the WR2 and WY Series and S&L Class systems that include the outdoor and indoor models covered by previously granted waivers in the WR2 and WY Series Waiver and the S&L Class Waiver, plus the additional indoor models that are the subject of this petition. MEUS respectfully requests that DOE replace, in its entirety, the lists of models included in the WR2 and WY Series Waiver and the S&L Class Waiver with the lists included as Attachment A and Attachment B to this petition upon grant of this waiver petition. Having an updated comprehensive list will assist DOE and market participants in easily keeping track of all of the WR2 and WY Series and S&L Class models that are subject to a DOE-granted waiver. Test Procedures From Which Waiver Is Requested MEUS’s petition requests waiver from the applicable test procedures for its additional indoor models to be used with the WR2 and WY Series and S&L Class CITY MULTI products. For the water source products, DOE’s regulations provide the test procedures for small and large commercial package air conditioning and heating equipment.7 Pursuant to 10 CFR § 431.96, the test procedures applicable to small commercial packaged air conditioning and heating water-source heat pumps, with capacities less than 135,000 Btu/h, are those included in ISO Standard 13256–1 (1998).8 The capacities of MEUS’s WR2 and WY CITY MULTI water-source products 7 10 6 S&L Class Waiver at 66317.

Therefore, MEUS requests waiver from ISO Standard 13256–1 (1998), as incorporated by reference in DOE’s regulations for its WR2 and WY Series products. MEUS’s petition also requests waiver from the commercial test procedures for its S&L Class products. For commercial package air conditioning equipment with capacities between 65,000 and 760,000 Btu/h, ARI Standard 340/360– 2004 is the applicable test procedure under 10 CFR § 431.96. The capacities of MEUS’s S&L Class CITY MULTI products sold for commercial use fall in that range. Therefore, MEUS requests waiver from ARI Standard 340/360– 2004 as incorporated by reference in DOE’s regulations for MEUS’s S&L Class products. MEUS proposes to test and rate a tested combination for each individual outdoor unit of the WR2 and WY Series products and the S&L Class products pursuant to the applicable alternate test procedure already specified in the WR2 and WY Series Waiver and the S&L Class Waiver, as discussed below. Need for Waiver of Test Procedures The Department’s regulations contain provisions allowing a person to seek a waiver from the test procedure requirements for commercial equipment. These provisions are set forth in 10 CFR § 431.401. The waiver provisions allow DOE to temporarily waive test procedures for a particular basic model when a petitioner shows that the basic model contains one or more design characteristics that prevent testing according to the prescribed test procedures, or when the prescribed test procedures may evaluate the basic model in a manner so unrepresentative of its true energy consumption as to provide materially inaccurate comparative data.9 As explained above, DOE granted the WR2 and WY Series products a waiver because ‘‘the basic model [of these products] contains one or more design characteristics which * * * prevent testing of the basic model according to the prescribed test procedures.’’ 10 DOE made the same finding with respect to the S&L Class products, stating that the existing testing facilities have limited ability to test multiple indoor units at one time, and that the number of possible combinations of indoor and outdoor units is impractical to test, and thus granted MEUS’s requested 9 10 CFR § 431.401(a)(1). and WY Series Waiver at 66313. 10 WR2 E:\FR\FM\06APN1.SGM 06APN1 19084 Federal Register / Vol. 76, No. 66 / Wednesday, April 6, 2011 / Notices waiver.11 The additional indoor models that are the subject of this petition would be used just as the products covered by the WR2 and WY Series Waiver and the S&L Class Waiver, and thus present exactly the same testing challenges. Thus, DOE should grant the requested waiver. As DOE found in its grant of the WR2 and WY Series Waiver and the S&L Class Waiver, indoor models are not the primary efficiency drivers for these systems—the primary efficiency drivers are the outdoor units.12 MEUS is not proposing to add new outdoor units to the WR2 and WY Series Waiver and S&L Class Waiver. The indoor units described above will be combined with the same outdoor unit models covered by the prior waivers to create VRFZ systems. It should be noted that these CITY MULTI products employ advanced technologies and their marketing will advance the goals of the Energy Policy and Conservation Act (EPCA) to promote energy efficiency. Testing procedures should not inhibit the commercial success of these products in the United States. Without a waiver of the test procedures, MEUS will be at a competitive disadvantage in the market. Consumers have come to expect the availability of the CITY MULTI products in the U.S. marketplace, and a significant number of engineers and contractors are currently requesting these WR2 and WY and S&L Class products for their projects because of the great advantages they offer. Thus, MEUS respectfully requests that DOE grant a waiver from the applicable test procedures. Alternative Test Procedures mstockstill on DSKH9S0YB1PROD with NOTICES Both the WR2 and WY Series Waiver and the S&L Class Waiver include alternate test procedures pursuant to which MEUS tests and rates its water source and S&L class products.13 No changes to those alternate test procedures are needed to cover the additional indoor units that are the subject of this petition. Therefore, MEUS requests that the products listed herein be subject to the same alternate test procedures as in the WR2 and WY Series Waiver and the S&L Class Waiver, as applicable. Class Waiver at 66317. believes that allowing MEUS to make energy efficiency representations for non-tested combinations by adopting this alternative test procedure as described above is reasonable because the outdoor unit is the principal efficiency driver.’’ S&L Class Waiver at 66317. See also WR2 and WY Series Waiver at 66313. 13 WR2 and WY Series Waiver at 66313; S&L Class Waiver at 66317. For DOE’s convenience, MEUS is reproducing the alternate test procedures included in the WR2 and WY Series Waiver and the S&L Class Waiver as Attachment C and Attachment D to this petition. Similar Products To the best of our knowledge, watersource VRFZ products or products similar to MEUS’s S&L Class products are also offered in the United States by Daikin AC (Americas), LG Electronics U.S.A., Inc., Fujitsu Gen America Inc, Samsung Electronics Company, LTD., and Sanyo Fisher (USA) Corp. Application for Interim Waiver Pursuant to 10 CFR § 431.401(a)(2), MEUS also submits an application for interim waiver of the applicable test procedures for the WR2 and WY CITY MULTI indoor models and the S&L Class indoor models listed above. DOE’s regulations contain provisions allowing DOE to grant an interim waiver from the test procedure requirements to manufacturers that have petitioned the Department for a waiver of such prescribed test procedures.14 As DOE has stated, ‘‘an Interim Waiver will be granted if it is determined that the applicant will experience economic hardship if the Application for Interim Waiver is denied, if it appears likely that the Petition for Waiver will be granted, and/or the Assistant Secretary determines that it would be desirable for public policy reasons to grant immediate relief pending a determination for the Petition for Waiver.’’ 15 MEUS will experience economic hardship if the application for interim waiver is denied. Additionally, precedent indicates that DOE will likely grant MEUS’s petition for waiver. Finally, it is in the public interest to grant an interim waiver. Therefore, MEUS respectfully requests DOE to grant the application for interim waiver. MEUS plans to introduce the additional WR2 and WY Series and the S&L Class indoor models into the U.S. market soon. The procedure for granting a waiver is a time-consuming process— DOE must publish the request in the Federal Register, allow time for public comment, and then consider any comments before it makes a decision. Thus, the process typically takes a 11 S&L 12 ‘‘DOE VerDate Mar<15>2010 16:52 Apr 05, 2011 Jkt 223001 14 10 CFR § 431.401(a)(2).

If an interim waiver is not granted, MEUS will suffer economic hardship because MEUS will be required to delay its introduction of these products to U.S. customers. In addition, DOE will likely grant MEUS’s request to update the previously-granted waivers to include the products covered by this request. As described above, DOE has already granted a waiver for the WR2 and WY Series and S&L Class products. The indoor models that are the subject of this request include the same design characteristics that prevented testing of the basic model of the products listed in the WR2 and WY Series Waiver and the S&L Class Waiver. The best evidence that DOE is likely to grant this request is the fact that it previously granted similar waivers to MEUS and other manufacturers.16 16 See WR2 and WY Series Waiver and the S&L Class Waiver.

In response to MEUS’s Application for Interim Waiver for its WR2 and WY products, DOE stated that ‘‘in those instances where the likely success of the Petition for Waiver has been demonstrated, based upon DOE having granted a waiver for a similar product design, it is in the public interest to have similar products tested and rated for energy consumption on a comparable basis.’’ 17 The same conclusion should be reached with respect to the additional indoor models listed in this petition. These products will suffer the same testing obstacles as the products covered by the earlier waivers. Therefore, since it is in the public interest to have similar products tested and rated on a comparable basis, DOE should grant MEUS’s Application for Interim Waiver. mstockstill on DSKH9S0YB1PROD with NOTICES Conclusion MEUS respectfully requests that DOE update the list of models covered by WR2 and WY Series Waiver and the S&L Class Waiver to cover the additional indoor models listed in this request.

SUPPLEMENTARY INFORMATION: 

I. Background and Authority

    Title III of the Energy Policy and Conservation Act (EPCA) sets 
forth a variety of provisions concerning energy efficiency, including 
Part B of Title III, which establishes the ``Energy Conservation 
Program for Consumer Products Other Than Automobiles.'' (42 U.S.C. 
6291-6309) Part C of Title III provides for a similar energy efficiency 
program titled ``Certain Industrial Equipment,'' which includes 
commercial air conditioning equipment, package boilers, water heaters, 
and other types of commercial equipment.\1\ (42 U.S.C. 6311-6317)
---------------------------------------------------------------------------

    \1\ For editorial reasons, upon codification in the U.S. Code, 
Part C was re-designated Part A-1.
---------------------------------------------------------------------------

    Today's notice involves commercial equipment under Part C. Part C 
specifically includes definitions (42 U.S.C. 6311), test procedures (42 
U.S.C. 6314), labeling provisions (42 U.S.C. 6315), energy conservation 
standards (42 U.S.C 6313), and the authority to require information and 
reports from manufacturers (42 U.S.C. 6316). With respect to test 
procedures, Part C authorizes the Secretary of Energy (the Secretary) 
to prescribe test procedures that are reasonably designed to produce 
results that measure energy efficiency, energy use, and estimated 
annual operating costs, and that are not unduly burdensome to conduct. 
(42 U.S.C. 6314(a)(2))
    For commercial package air-conditioning and heating equipment, EPCA 
provides that ``the test procedures shall be those generally accepted 
industry testing procedures or rating procedures developed or 
recognized by the Air-Conditioning and Refrigeration Institute [ARI] or 
by the American Society of Heating, Refrigerating and Air-Conditioning 
Engineers [ASHRAE], as referenced in ASHRAE/IES Standard 90.1 and in 
effect on June 30, 1992.'' (42 U.S.C. 6314(a)(4)(A)) Under 42 U.S.C. 
6314(a)(4)(B), the statute further directs the Secretary to amend the 
test procedure for a covered commercial product if the industry test 
procedure is amended, unless the Secretary determines, by rule and 
based on clear and convincing evidence, that such a modified test 
procedure does not meet the statutory criteria set forth in 42 U.S.C. 
6314(a)(2) and (3).
    On December 8, 2006, DOE published a final rule adopting test 
procedures for commercial package air-conditioning and heating 
equipment, effective January 8, 2007. 71 FR 71340. Table 1 to Title 10 
of the Code of Federal Regulations (10 CFR) 431.96 directs 
manufacturers of commercial package air conditioning and heating 
equipment to use the appropriate procedure when measuring energy 
efficiency of those products. The test procedures applicable to small 
commercial packaged air conditioning and heating water-source heat 
pumps, with capacities less than 135,000 Btu/h, are those included in 
ISO Standard 13256-1 (1998). The capacities of Mitsubishi's WR2 and WY 
CITY MULTI water-source products covered by this petition fall in that 
range. For commercial package air-source equipment with capacities 
between 65,000 and 760,000 Btu/h, ARI Standard 340/360-2004 is the 
applicable test procedure under 10 CFR 431.96. The capacities of 
Mitsubishi's S&L Class CITY MULTI commercial products fall in that 
range.
    DOE's regulations for covered products permit a person to seek a 
waiver from the test procedure requirements for covered commercial 
equipment if at least one of the following conditions is met: (1) The 
petitioner's basic model contains one or more design characteristics 
that prevent testing according to the prescribed test procedures; or 
(2) the prescribed test procedures may evaluate the basic model in a 
manner so unrepresentative of its true energy consumption as to provide 
materially inaccurate comparative data. 10 CFR 431.401(a)(1). 
Petitioners must include in their petition any alternate test 
procedures known to the petitioner to evaluate the basic model in a 
manner representative of its energy consumption. 10 CFR 
431.401(b)(1)(iii). The Assistant Secretary for Energy Efficiency and 
Renewable Energy (Assistant Secretary) may grant a waiver subject to 
conditions, including adherence to alternate test procedures. 10 CFR 
431.401(f)(4). Waivers remain in effect pursuant to the provisions of 
10 CFR 431.401(g).
    The waiver process also permits parties submitting a petition for 
waiver to file an application for interim waiver of the applicable test 
procedure requirements. 10 CFR 431.401(a)(2). The Assistant Secretary 
will grant an interim waiver request if it is determined that the 
applicant will experience economic hardship if the application for 
interim waiver is denied, if it appears likely that the petition for 
waiver will be granted, and/or the Assistant Secretary determines that 
it would be desirable for public policy reasons to grant immediate 
relief pending a

[[Page 19080]]

determination on the petition for waiver. 10 CFR 431.401(e)(3). An 
interim waiver remains in effect for 180 days or until DOE issues its 
determination on the petition for waiver, whichever occurs first. It 
may be extended by DOE for an additional 180 days. 10 CFR 
431.401(e)(4).

II. Petition for Waiver

    On February 18, 2011, Mitsubishi filed an application for interim 
waiver and a petition for waiver from the test procedures under 10 CFR 
431.96 that apply to commercial package air and water-source air 
conditioners and heat pumps. Mitsubishi's petition requests a waiver 
from the applicable test procedures for its additional indoor models to 
be used with the WR2 and WY Series and S&L Class CITY MULTI products.
    On December 15, 2009, DOE granted Mitsubishi waivers from the DOE 
commercial air conditioner and heat pump test procedures for 
Mitsubishi's WR2 and WY Series products and the S&L Class products. 74 
FR 66311, 66315. Mitsubishi's February 18, 2011 petition lists 
additional models of indoor units for these multi-split systems. These 
include models in existing model families that have capacities not 
previously offered, as well as new indoor model families to be used 
with these systems. These additional indoor models face the same 
testing challenges as the models already covered by the WR2 and WY 
Series Waiver and the S&L Class Waiver.
    Mitsubishi seeks a waiver from the applicable test procedures under 
10 CFR 431.96 on the grounds that its WR2, WY and S&L Class multi-split 
heat pumps contain design characteristics that prevent testing 
according to the current DOE test procedures. DOE granted the WR2 and 
WY Series products a waiver because the basic model of these products 
contains one or more design characteristics that prevent testing of the 
basic model according to the prescribed test procedures. DOE made the 
same finding with respect to the S&L Class products, stating that the 
existing testing facilities have limited ability to test multiple 
indoor units at one time, and that the number of possible combinations 
of indoor and outdoor units is impractical to test, and thus granted 
Mitsubishi's requested waiver. The additional indoor models that are 
the subject of this petition would be used just as the products covered 
by the WR2 and WY Series Waiver and the S&L Class Waiver, and thus 
present exactly the same testing challenges.
    As DOE found in its grant of the WR2 and WY Series Waiver and the 
S&L Class Waiver, indoor models are not the primary efficiency drivers 
for these systems--the primary efficiency drivers are the outdoor 
units. Mitsubishi is not proposing to add new outdoor units to the WR2 
and WY Series Waiver and S&L Class Waiver. The indoor units described 
above will be combined with the same outdoor unit models covered by the 
prior waivers to create multi-split systems.

III. Application for Interim Waiver

    On February 18, 2011, Mitsubishi also submitted an application for 
an interim waiver from the test procedures at 10 CFR 431.96 for its 
specified WR2, WY, and S&L equipment. DOE determined that Mitsubishi's 
application for interim waiver does not provide sufficient market, 
equipment price, shipments, and other manufacturer impact information 
to permit DOE to evaluate the economic hardship Mitsubishi might 
experience absent a favorable determination on its application for an 
interim waiver. DOE understands, however, that if it did not issue an 
interim waiver, Mitsubishi's products would not be tested and rated for 
energy consumption in the same manner as similar products for which DOE 
previously granted waivers. Furthermore, DOE has determined that it 
appears likely that Mitsubishi's petition for waiver will be granted 
and that is desirable for public policy reasons to grant Mitsubishi 
immediate relief pending a determination on the petition for waiver. 
DOE believes that it is likely Mitsubishi's petition for waiver for the 
new WR2, WY and S&L Class multi-split models will be granted because 
DOE has previously granted a number of waivers for similar product 
designs. The two principal reasons supporting the grant of the previous 
waivers also apply to Mitsubishi's WR2, WY and S&L Class products: (1) 
Test laboratories cannot test products with so many indoor units; and 
(2) it is impractical to test so many combinations of indoor units with 
each outdoor unit. In addition, DOE believes that similar products 
should be tested and rated for energy consumption on a comparable 
basis. For these same reasons, DOE also determined that it is desirable 
for public policy reasons to grant immediate relief pending a 
determination on the petition for waiver.
    Therefore, it is ordered that:
    The application for interim waiver filed by Mitsubishi is hereby 
granted for Mitsubishi's WR2, WY and S&L Class multi-split heat pumps, 
subject to the specifications and conditions below.
    1. Mitsubishi shall not be required to test or rate its WR2, WY and 
S&L Class commercial multi-split products on the basis of the existing 
test procedures under 10 CFR 431.96, which incorporates by reference 
ARI 340/360-2004 (S&L Class) and ISO Standard 13256-1 (1998) (WR2 and 
WY classes).
    2. Mitsubishi shall be required to test and rate its WR2, WY and 
S&L Class commercial multi-split products according to the alternate 
test procedure as set forth in section IV(3), ``Alternate test 
procedure.''
    The interim waiver applies to the following indoor units:
     PCFY--Series--Ceiling Suspended--with a capacity of 15 
MBtu/h
     PEFY Series--Ceiling Concealed Ducted (Low Profile)--with 
a capacity of 15 MBtu/h
     PKFY Series--Wall Mounted--with a capacity of 15 MBtu/h
     PLFY Series--4-Way Airflow Ceiling Cassette--with a 
capacity of 15 MBtu/h
     The PEFY-AF Series--100% outdoor air ventilation systems 
(Concealed ducted)--PEFY-AF1200CFM/CFMR**--with a maximum outside air 
ventilation capability of 1200 CFM
     The PVFY Series-Vertical air handler (Concealed ducted)--
with capacities of 12/18/24/30/36/42/48/54 MBtu/h
     PWFY Series--Commercial Hot Water Heat Pump Indoor Units--
with capacities of 36/72 MBtu/h and 36 MBtu/h with booster unit.
     PEFY Series--Ceiling Concealed Ducted--with capacities of 
06/08/12/15/18/24/27/30/36/48 MBtu/h
     PLFY Series--2'-by-2' frame 4-Way Airflow Ceiling 
Cassette--with capacities of 8/12/15 MBtu/h
    This interim waiver is issued on the condition that the statements, 
representations, and documents provided by the petitioner are valid. 
DOE may revoke or modify this interim waiver at any time if it 
determines the factual basis underlying the petition for waiver is 
incorrect or the results from the alternate test procedure are 
unrepresentative of the basic models' true energy consumption 
characteristics.
    DOE makes decisions on waivers and interim waivers for only those 
models specifically set out in the petition, not future models that may 
be manufactured by the petitioner. MEUS may submit a new or amended 
petition for waiver and request for grant of interim waiver, as 
appropriate, for additional models of commercial package air 
conditioners and heat pumps for which it seeks a waiver from the DOE 
test procedure. In

[[Page 19081]]

addition, DOE notes that grant of an interim waiver or waiver does not 
release a petitioner from the certification requirements set forth at 
10 CFR Part 431, Subpart T.

IV. Alternate Test Procedure

    In responses to petitions for waiver from Mitsubishi, DOE specified 
an alternate test procedure to provide a basis from which Mitsubishi 
could test and make valid energy efficiency representations for its 
R410A CITY MULTI products, as well as for its R22 multi-split products. 
Alternate test procedures related to the Mitsubishi petitions were 
published in the Federal Register on April 9, 2007. See 72 FR 17528 and 
72 FR 17533. The same alternate test procedure was specified in the 
December 15, 2009 waivers. For reasons similar to those published in 
these prior notices, DOE believes that an alternate test procedure is 
appropriate in this instance.
    We further note that after DOE granted a waiver for Mitsubishi's 
multi-split products, ARI formed a committee to discuss testing issues 
and to develop a testing protocol for variable refrigerant flow 
systems. The committee has developed a test procedure which has been 
adopted by AHRI--``ANSI/AHRI 1230--2010: Performance Rating of Variable 
Refrigerant Flow (VRF) Multi-Split Air-Conditioning and Heat Pump 
Equipment'' and incorporated into ASHRAE 90.1--2010. The commercial 
multisplit waivers that DOE has granted to Mitsubishi and several other 
manufacturers and the alternate test procedure set forth in those 
waivers are consistent with AHRI 1230-2010. The waivers use a 
definition of ``tested combination'' that is substantially the same as 
the definition in AHRI 1230-2010. As a result, DOE is considering 
prescribing ANSI/AHRI 1230-2010 in the subsequent decision and order as 
the alternate test procedure for this Mitsubishi waiver. For the 
interim waiver, however, DOE will continue to require the use of the 
alternate test procedure prescribed in the past multisplit waivers.
    Therefore, as a condition for granting this interim waiver to 
Mitsubishi, DOE is including an alternate test procedure similar to 
those granted to Mitsubishi in its previous waivers and identical to 
the ones granted on December 15, 2009. This alternate test procedure 
will allow Mitsubishi to test and make energy efficiency 
representations for its WR2, WY and S&L Class products. DOE has applied 
a similar alternate test procedure to other waivers for similar 
residential and commercial central air conditioners and heat pumps 
manufactured by Mitsubishi (72 FR 17528, April 9, 2007); Samsung (72 FR 
71387, Dec. 17, 2007); Fujitsu (72 FR 71383, Dec. 17, 2007); Daikin (73 
FR 39680, July 10, 2008); Daikin (74 FR 15955, April 8, 2009); Daikin 
(74 FR 16193, April 9, 2009); Daikin (74 FR 16373, April 10, 2009); 
Mitsubishi (74 FR 66311, 66315, December 15, 2009) and LG (74 FR 66330, 
December 15, 2009).
    The alternate test procedure developed in conjunction with the 
Mitsubishi waiver permits Mitsubishi to designate a ``tested 
combination'' for each model of outdoor unit. The indoor units 
designated as part of the tested combination must meet specific 
requirements. For example, the tested combination must have from two to 
eight indoor units so that it can be tested in available test 
facilities. (The ``tested combination'' was originally defined to 
consist of one outdoor unit matched with between 2 and 5 indoor units. 
The maximum number of indoor units in a tested combination is increased 
in this instance from 5 to 8 to account for the fact that these larger-
capacity products can accommodate a greater number of indoor units.) 
The tested combination must be tested according to the applicable DOE 
test procedure, as modified by the provisions of the alternate test 
procedure as set forth below. The alternate test procedure also allows 
manufacturers of such products to make valid and consistent 
representations of energy efficiency for their air-conditioning and 
heat pump products.
    DOE plans to consider inclusion of the following waiver language in 
the decision and order for Mitsubishi's WR2, WY and S&L Class 
commercial multi-split water-source heat pump models:

    Mitsubishi shall not be required to test or rate its WR2, WY and 
S&L Class commercial multi-split heat pumps according to the 
existing test procedures under Table 1 of 10 CFR 431.96, which 
incorporates by reference the Air-Conditioning and Refrigeration 
Institute (ARI) Standard 340/360-2004 for the air-source S&L Class 
products, and ISO Standard 13256-1998 for the water-source WR2 and 
WY Series products. Mitsubishi will be required, however, to test 
and rate its WR2, WY and S&L Class commercial multi-split heat pumps 
covered in this waiver according to the alternate test procedure as 
set forth below:
    (A) Mitsubishi shall be required to test the basic models of 
WR2, WY and S&L Class water and air-source outdoor units and 
compatible indoor units listed in its petition for waiver dated 
February 18, 2011, according to the test procedures for commercial 
central air conditioners and heat pumps prescribed under 10 CFR 
431.96, except that Mitsubishi shall test a ``tested combination'' 
selected in accordance with the provisions of subparagraph (B). For 
every other system combination using the same outdoor unit as the 
tested combination, Mitsubishi shall make representations concerning 
the WR2, WY and S&L Class equipment covered in this interim waiver 
according to the provisions of subparagraph (C).
    (B) Tested combination. The term tested combination means a 
sample basic model comprised of units that are production units, or 
are representative of production units, of the basic model being 
tested. For the purposes of this waiver, the tested combination 
shall have the following features:
    (1) The basic model of a variable refrigerant flow system used 
as a tested combination shall consist of one outdoor unit, with one 
or more compressors, that is matched with between two and five 
indoor units. (For systems with nominal cooling capacities greater 
than 150,000 Btu/h, as many as eight indoor units may be used, so 
that non-ducted indoor unit combinations can also be tested.) For 
multi-split systems, each of these indoor units shall be designed 
for individual operation.
    (2) The indoor units shall--
    (i) Represent the highest sales model family or another indoor 
model family if the highest sales model family does not provide 
sufficient capacity (see ii);
    (ii) Together, have a nominal cooling capacity that is between 
95% and 105% of the nominal cooling capacity of the outdoor unit;
    (iii) Not, individually, have a nominal cooling capacity that is 
greater than 50% of the nominal cooling capacity of the outdoor 
unit;
    (iv) Operate at fan speeds that are consistent with the 
manufacturer's specifications; and
    (v) Be subject to the same minimum external static pressure 
requirement while being configurable to produce the same static 
pressure at the exit of each outlet plenum when manifolded as per 
section 2.4.1 of 10 CFR part 430, subpart B, appendix M.
    (C) Representations. In making representations about the energy 
efficiency of its WR2, WY and S&L Class variable capacity multi-
split heat pump products for compliance, marketing, or other 
purposes, Mitsubishi must fairly disclose the results of testing 
under the DOE test procedure in a manner consistent with the 
provisions outlined below:
    (1) For WR2, WY and S&L Class combinations tested in accordance 
with this alternate test procedure, Mitsubishi may make 
representations based on these test results.
    (2) For WR2, WY and S&L Class combinations that are not tested, 
Mitsubishi may make representations of non-tested combinations at 
the same energy efficiency level as the tested combination. The 
outdoor unit must be the one used in the tested combination. The 
representations must be based on the test results for the tested 
combination. The representations may also be determined by an 
Alternative Rating Method approved by DOE.

Re: Update to Previously-Granted Test Procedure Waivers for CITY MULTI 
VRFZ WR2 and WY Series and S&L Class Air Conditioners and Heat Pumps

Dear Assistant Secretary Zoi:

    On December 15, 2009, the Department of Energy (DOE) granted 
Mitsubishi Electric & Electronics USA, Inc. (MEUS) a waiver from the 
DOE commercial air conditioner and heat pump test procedures for MEUS's 
WR2 and WY Series products \1\ and the S&L Class products.\2\ These 
products are part of MEUS's CITY MULTI Variable Refrigerant Flow Zoning 
(VRFZ) line of multi-split central air conditioners and heat pumps. As 
explained in MEUS's petitions for waiver for the WR2 and WY Series and 
the S&L Class products, these systems cannot be tested according to the 
prescribed test procedures for commercial products. Pursuant to DOE's 
grant of the waivers, MEUS is not required to test or rate the products 
listed in the waivers based on the currently applicable test procedure. 
Instead, MEUS is required to test and rate these products according to 
the alternate test procedure set forth in the waivers.
---------------------------------------------------------------------------

    \1\ Energy Conservation Program for Certain Industrial 
Equipment: Decision and Order Granting a Waiver to Mitsubishi 
Electric and Electronics USA, Inc. From the Department of Energy 
Commercial Package Water-Source Heat Pump Test Procedure, 74 Fed. 
Reg. 66311 (Dec. 15, 2009) (``WR2 and WY Series Waiver'').

Electric & Electronics USA, Inc. From the Department of Energy 
Commercial Package Air Conditioner and Heat Pump Test Procedures, 74 
Fed. Reg. 66315 (Dec. 15, 2009) (``S&L Class Waiver'').
---------------------------------------------------------------------------

    MEUS has now developed additional models of indoor units for these 
multi-split systems. These include both models in certain existing 
model families that have capacities not previously offered, as well as 
new indoor model families to be used with these systems. These 
additional indoor models face the same testing challenges as the models 
already covered by the WR2 and WY Series Waiver and the S&L Class 
Waiver. Specifically, they contain one or more design characteristic 
that prevents testing according to the test procedures. Therefore, MEUS 
respectfully requests that DOE update the list of models covered by the 
applicable test procedure waivers to cover these additional indoor 
models.\3\ MEUS simultaneously requests an interim waiver covering 
systems using these additional indoor models.
---------------------------------------------------------------------------

    \3\ The existing WR2 and WY Series Waiver and S&L Class Waiver 
would remain in effect until DOE modifies those waivers in 
accordance with this request.
---------------------------------------------------------------------------

    MEUS frames this request to update the list of models covered by 
two already-granted waivers pursuant to the requirements for granting 
new test procedure waivers.\4\ Given that this request simply addresses 
the addition of certain new indoor models for MEUS's WR2 and WY Series 
and the S&L Class products, and that DOE previously has granted waivers 
for the outdoor units and other indoor units for these systems, if DOE 
would prefer to utilize a procedurally simpler approach for updating 
the covered list of models, MEUS would welcome such an approach.
---------------------------------------------------------------------------

    \4\ See 10 CFR Sec.  431.401.
---------------------------------------------------------------------------

Background

    On October 30, 2006, MEUS submitted a Petition for Waiver from the 
test procedures applicable to the water-source WR2 and WY Series of its 
CITY MULTI VRFZ line of commercial package heat pump equipment. 
Mitsubishi sought a waiver from the applicable test procedures because 
the design characteristics of these models prevented testing according 
to the currently prescribed test procedures. Specifically, these models 
can connect an outdoor unit to many more indoor units than the test 
laboratories can physically test at one time, and it is not practical 
to test all of the potentially available combinations. DOE granted the 
requested waiver because ``the basic model [of these products] contains 
one or more design characteristics which * * * prevent testing of the 
basic model according to the prescribed test procedures.'' \5\ The 
waiver included an alternate test procedure pursuant to which MEUS must 
test and rate the products covered by the waiver.
---------------------------------------------------------------------------

    \5\ WR2 and WY Series Waiver at 66313.
---------------------------------------------------------------------------

    On March 28, 2008, MEUS submitted a Petition for Waiver from the 
test procedures applicable to the S&L Class models from MEUS's CITY 
MULTI VRFZ line of commercial package heat pump equipment. MEUS based 
its request on the fact that the testing laboratories cannot test 
systems with so many indoor units, and that there are

[[Page 19083]]

too many possible combinations of indoor units with a single outdoor 
unit to test. DOE agreed with MEUS that the existing testing facilities 
have limited ability to test multiple indoor units at one time, and 
that the number of possible combinations of indoor and outdoor units is 
impractical to test, and thus granted MEUS's requested waiver.\6\ DOE 
approved an alternate test procedure pursuant to which MEUS must test 
and rate the models covered by the waiver.
---------------------------------------------------------------------------

    \6\ S&L Class Waiver at 66317.
---------------------------------------------------------------------------

New Indoor Models

    Both the WR2 and WY Series Waiver and the S&L Class Waiver covered 
the following indoor model families: (1) PCFY Series--Ceiling 
Suspended; (2) PEFY Series--Ceiling Concealed Ducted (Low Profile); (3) 
PKFY Series--Wall Mounted; and (4) PLFY Series--4-Way Airflow Ceiling 
Cassette. For each of these indoor model families, MEUS has developed 
an additional model with a capacity of 15 MBtu/h. At the time MEUS 
initially filed its petitions for waiver for the WR2 and WY Series and 
S&L Class products, this capacity product was not available. MEUS has 
developed this additional capacity product to meet customer demands for 
specialized applications.
    When MEUS originally applied for a waiver for its WR2 and WY Series 
and its S&L Class products, it only included those indoor units that 
were being produced at that time. MEUS has now developed new indoor 
model types to expand its CITY MULTI product line to offer consumers a 
greater variety of available indoor units to suit consumers' specific 
needs. MEUS plans to add five new types of indoor unit families to the 
line-up of indoor units that can be matched with the CITY MULTI outdoor 
units. The new indoor model families will be: (1) PEFY-AF; (2) PVFY; 
(3) PWFY; (4) PLFY Series--2'-by-2' frame 4-Way Airflow Ceiling 
Cassette; and (5) PEFY Series--Ceiling Concealed Ducted. The difference 
between these new indoor models and the models previously covered by 
the waivers relates to their application. All of the new models have 
been developed for specialized applications to meet consumers' unique 
demands.
    MEUS requests that the WR2 and WY Series Waiver and the S&L Class 
Waiver be updated to cover the following additional indoor units:
     PCFY-Series-Ceiling Suspended--with a capacity of 15 MBtu/
h
     PEFY Series-Ceiling Concealed Ducted (Low Profile)--with a 
capacity of 15 MBtu/h
     PKFY Series-Wall Mounted--with a capacity of 15 MBtu/h
     PLFY Series-4-Way Airflow Ceiling Cassette--with a 
capacity of 15 MBtu/h
     The PEFY-AF Series--100% outdoor air ventilation systems 
(Concealed ducted)--PEFY-AF1200CFM/CFMR**--with a maximum outside air 
ventilation capability of 1200 CFM
     The PVFY Series--Vertical air handler (Concealed ducted)--
with capacities of 12/18/24/30/36/42/48/54 MBtu/h
     PWFY Series--Commercial Hot Water Heat Pump Indoor Units--
with capacities of 36/72 MBtu/h and 36 MBtu/h with booster unit.
     PEFY Series--Ceiling Concealed Ducted--with capacities of 
06/08/12/15/18/24/27/30/36/48 MBtu/h
     PLFY Series--2'-by-2' frame 4-Way Airflow Ceiling 
Cassette--with capacities of 8/12/15 MBtu/h
    For DOE's convenience, MEUS is attaching comprehensive lists of all 
of the models for the WR2 and WY Series and S&L Class systems that 
include the outdoor and indoor models covered by previously granted 
waivers in the WR2 and WY Series Waiver and the S&L Class Waiver, plus 
the additional indoor models that are the subject of this petition. 
MEUS respectfully requests that DOE replace, in its entirety, the lists 
of models included in the WR2 and WY Series Waiver and the S&L Class 
Waiver with the lists included as Attachment A and Attachment B to this 
petition upon grant of this waiver petition. Having an updated 
comprehensive list will assist DOE and market participants in easily 
keeping track of all of the WR2 and WY Series and S&L Class models that 
are subject to a DOE-granted waiver.

Test Procedures From Which Waiver Is Requested

    MEUS's petition requests waiver from the applicable test procedures 
for its additional indoor models to be used with the WR2 and WY Series 
and S&L Class CITY MULTI products.
    For the water source products, DOE's regulations provide the test 
procedures for small and large commercial package air conditioning and 
heating equipment.\7\ Pursuant to 10 CFR Sec.  431.96, the test 
procedures applicable to small commercial packaged air conditioning and 
heating water-source heat pumps, with capacities less than 135,000 Btu/
h, are those included in ISO Standard 13256-1 (1998).\8\ The capacities 
of MEUS's WR2 and WY CITY MULTI water-source products covered by this 
petition fall in that range. Therefore, MEUS requests waiver from ISO 
Standard 13256-1 (1998), as incorporated by reference in DOE's 
regulations for its WR2 and WY Series products.
---------------------------------------------------------------------------

    \7\ 10 CFR Sec.  431.96.
    \8\ 10 CFR Sec.  431.96, Table 1.
---------------------------------------------------------------------------

    MEUS's petition also requests waiver from the commercial test 
procedures for its S&L Class products. For commercial package air 
conditioning equipment with capacities between 65,000 and 760,000 Btu/
h, ARI Standard 340/360-2004 is the applicable test procedure under 10 
CFR Sec.  431.96. The capacities of MEUS's S&L Class CITY MULTI 
products sold for commercial use fall in that range. Therefore, MEUS 
requests waiver from ARI Standard 340/360-2004 as incorporated by 
reference in DOE's regulations for MEUS's S&L Class products.
    MEUS proposes to test and rate a tested combination for each 
individual outdoor unit of the WR2 and WY Series products and the S&L 
Class products pursuant to the applicable alternate test procedure 
already specified in the WR2 and WY Series Waiver and the S&L Class 
Waiver, as discussed below.

Need for Waiver of Test Procedures

    The Department's regulations contain provisions allowing a person 
to seek a waiver from the test procedure requirements for commercial 
equipment. These provisions are set forth in 10 CFR Sec.  431.401. The 
waiver provisions allow DOE to temporarily waive test procedures for a 
particular basic model when a petitioner shows that the basic model 
contains one or more design characteristics that prevent testing 
according to the prescribed test procedures, or when the prescribed 
test procedures may evaluate the basic model in a manner so 
unrepresentative of its true energy consumption as to provide 
materially inaccurate comparative data.\9\
---------------------------------------------------------------------------

    \9\ 10 CFR Sec.  431.401(a)(1).
---------------------------------------------------------------------------

    As explained above, DOE granted the WR2 and WY Series products a 
waiver because ``the basic model [of these products] contains one or 
more design characteristics which * * * prevent testing of the basic 
model according to the prescribed test procedures.'' \10\ DOE made the 
same finding with respect to the S&L Class products, stating that the 
existing testing facilities have limited ability to test multiple 
indoor units at one time, and that the number of possible combinations 
of indoor and outdoor units is impractical to test, and thus granted 
MEUS's requested

[[Page 19084]]

waiver.\11\ The additional indoor models that are the subject of this 
petition would be used just as the products covered by the WR2 and WY 
Series Waiver and the S&L Class Waiver, and thus present exactly the 
same testing challenges. Thus, DOE should grant the requested waiver.
---------------------------------------------------------------------------

    \10\ WR2 and WY Series Waiver at 66313.
    \11\ S&L Class Waiver at 66317.
---------------------------------------------------------------------------

    As DOE found in its grant of the WR2 and WY Series Waiver and the 
S&L Class Waiver, indoor models are not the primary efficiency drivers 
for these systems--the primary efficiency drivers are the outdoor 
units.\12\ MEUS is not proposing to add new outdoor units to the WR2 
and WY Series Waiver and S&L Class Waiver. The indoor units described 
above will be combined with the same outdoor unit models covered by the 
prior waivers to create VRFZ systems.

    \12\ ``DOE believes that allowing MEUS to make energy efficiency 
representations for non-tested combinations by adopting this 
alternative test procedure as described above is reasonable because 
the outdoor unit is the principal efficiency driver.'' S&L Class 
Waiver at 66317. See also WR2 and WY Series Waiver at 66313.
---------------------------------------------------------------------------

    It should be noted that these CITY MULTI products employ advanced 
technologies and their marketing will advance the goals of the Energy 
Policy and Conservation Act (EPCA) to promote energy efficiency. 
Testing procedures should not inhibit the commercial success of these 
products in the United States. Without a waiver of the test procedures, 
MEUS will be at a competitive disadvantage in the market. Consumers 
have come to expect the availability of the CITY MULTI products in the 
U.S. marketplace, and a significant number of engineers and contractors 
are currently requesting these WR2 and WY and S&L Class products for 
their projects because of the great advantages they offer. Thus, MEUS 
respectfully requests that DOE grant a waiver from the applicable test 
procedures.

Alternative Test Procedures

    Both the WR2 and WY Series Waiver and the S&L Class Waiver include 
alternate test procedures pursuant to which MEUS tests and rates its 
water source and S&L class products.\13\ No changes to those alternate 
test procedures are needed to cover the additional indoor units that 
are the subject of this petition. Therefore, MEUS requests that the 
products listed herein be subject to the same alternate test procedures 
as in the WR2 and WY Series Waiver and the S&L Class Waiver, as 
applicable.
---------------------------------------------------------------------------

    \13\ WR2 and WY Series Waiver at 66313; S&L Class Waiver at 
66317.
---------------------------------------------------------------------------

    For DOE's convenience, MEUS is reproducing the alternate test 
procedures included in the WR2 and WY Series Waiver and the S&L Class 
Waiver as Attachment C and Attachment D to this petition.

Similar Products

    To the best of our knowledge, water-source VRFZ products or 
products similar to MEUS's S&L Class products are also offered in the 
United States by Daikin AC (Americas), LG Electronics U.S.A., Inc., 
Fujitsu Gen America Inc, Samsung Electronics Company, LTD., and Sanyo 
Fisher (USA) Corp.

Application for Interim Waiver

    Pursuant to 10 CFR Sec.  431.401(a)(2), MEUS also submits an 
application for interim waiver of the applicable test procedures for 
the WR2 and WY CITY MULTI indoor models and the S&L Class indoor models 
listed above. DOE's regulations contain provisions allowing DOE to 
grant an interim waiver from the test procedure requirements to 
manufacturers that have petitioned the Department for a waiver of such 
prescribed test procedures.\14\ As DOE has stated, ``an Interim Waiver 
will be granted if it is determined that the applicant will experience 
economic hardship if the Application for Interim Waiver is denied, if 
it appears likely that the Petition for Waiver will be granted, and/or 
the Assistant Secretary determines that it would be desirable for 
public policy reasons to grant immediate relief pending a determination 
for the Petition for Waiver.'' \15\ MEUS will experience economic 
hardship if the application for interim waiver is denied. Additionally, 
precedent indicates that DOE will likely grant MEUS's petition for 
waiver. Finally, it is in the public interest to grant an interim 
waiver. Therefore, MEUS respectfully requests DOE to grant the 
application for interim waiver.

28, 2005). See 10 CFR Sec.  431.201(e)(3) (2005).
---------------------------------------------------------------------------

    MEUS plans to introduce the additional WR2 and WY Series and the 
S&L Class indoor models into the U.S. market soon. The procedure for 
granting a waiver is a time-consuming process--DOE must publish the 
request in the Federal Register, allow time for public comment, and 
then consider any comments before it makes a decision. Thus, the 
process typically takes a number of months. If an interim waiver is not 
granted, MEUS will suffer economic hardship because MEUS will be 
required to delay its introduction of these products to U.S. customers.
    In addition, DOE will likely grant MEUS's request to update the 
previously-granted waivers to include the products covered by this 
request. As described above, DOE has already granted a waiver for the 
WR2 and WY Series and S&L Class products. The indoor models that are 
the subject of this request include the same design characteristics 
that prevented testing of the basic model of the products listed in the 
WR2 and WY Series Waiver and the S&L Class Waiver. The best evidence 
that DOE is likely to grant this request is the fact that it previously 
granted similar waivers to MEUS and other manufacturers.\16\

    Finally, DOE's regulations state that the Assistant Secretary may 
grant an interim waiver if he determines that it would be desirable for 
public policy reasons to grant immediate relief pending a determination 
for the Petition for Waiver. In response to MEUS's Application for 
Interim Waiver for its WR2 and WY products, DOE stated that ``in those 
instances where the likely success of the Petition for Waiver has been 
demonstrated, based upon DOE having granted a waiver for a similar 
product design, it is in the public interest to have similar products 
tested and rated for energy consumption on a comparable basis.'' \17\ 
The same conclusion should be reached with respect to the additional 
indoor models listed in this petition. These products will suffer the 
same testing obstacles as the products covered by the earlier waivers. 
Therefore, since it is in the public interest to have similar products 
tested and rated on a comparable basis, DOE should grant MEUS's 
Application for Interim Waiver.

---------------------------------------------------------------------------

Conclusion

    MEUS respectfully requests that DOE update the list of models 
covered by WR2 and WY Series Waiver and the S&L Class Waiver to cover 
the additional indoor models listed in this request. DOE should grant 
this request because the list of covered products, as updated, 
``contain[] one or more design characteristics which * * * prevent 
testing of the basic model according to the prescribed test 
procedures.'' \18\ MEUS further requests DOE to grant its request for 
an interim waiver while this request is pending.

Attachment C

Alternate Test Procedure for the WR2 and WY Series (Established in the 
WR2 and WY Waiver, Dec. 15, 2009)

    (A) Mitsubishi shall be required to test its water-source WR2 
and WY series models of its CITY MULTI VRFZ equipment according to 
those test procedures for commercial package air conditioners and 
heat pumps prescribed at 10 CFR Part 431.96, except that:
    (i) Mitsubishi shall test a ``tested combination'' selected in 
accordance with the provisions of subparagraph (B) of this 
paragraph. For every other system combination using the same outdoor 
unit as the tested combination, Mitsubishi shall make 
representations concerning the WR2 and WY CITY MULTI equipment 
covered in this waiver according to the provisions of subparagraph 
(C) below.
    (B) Tested combination. The term ``tested combination'' means a 
sample basic model comprised of units that are production units, or 
are representative of production units, of the basic model being 
tested. For the purposes of this waiver, the tested combination 
shall have the following features:
    (1) The basic model of a variable refrigerant flow system used 
as a tested combination shall consist of an outdoor unit that is 
matched with between two and five indoor units.
    (2) The indoor units shall--
    (i) Represent the highest sales model family, or another indoor 
model family if the highest sales model family does not provide 
sufficient capacity (see ii);
    (ii) Together, have a nominal cooling capacity between 95 
percent and 105 percent of the nominal cooling capacity of the 
outdoor unit;
    (iii) Not, individually, have a nominal cooling capacity that is 
greater than 50 percent of the nominal cooling capacity of the 
outdoor unit;
    (iv) Operate at fan speeds that are consistent with the 
manufacturer's specifications; and
    (v) All be subject to the same minimum external static pressure 
requirement while being configurable to produce the same static 
pressure at the exit of each outlet plenum when manifolded as per 
section 2.4.1 of 10 CFR Part 430, Subpart B, Appendix M.
    (C) Representations. In making representations about the energy 
efficiency of its WR2 and WY CITY MULTI VRFZ equipment, for 
compliance, marketing, or other purposes, Mitsubishi must fairly 
disclose the results of testing under the DOE test procedure, doing 
so in a manner consistent with the provisions outlined below:
    (i) For WR2 and WY CITY MULTI VRFZ combinations tested in 
accordance with this alternate test procedure, Mitsubishi may make 
representations based on these test results.
    (ii) For WR2 and WY CITY MULTI VRFZ combinations that are not 
tested, Mitsubishi may make representations based on the testing 
results for the tested combination and which are consistent with 
either of the two following methods:
    (a) Representation of non-tested combinations according to an 
Alternative Rating Method (ARM) approved by DOE; or
    (b) Representation of non-tested combinations at the same energy 
efficiency level as the tested combination with the same outdoor 
unit.
    (5) This waiver shall remain in effect from the date of issuance 
of this Decision and Order consistent with the provisions of 10 CFR 
431.401(g).
    (6) This waiver is conditioned upon the presumed validity of 
statements, representations, and documentary materials provided by 
the petitioner. This waiver may be revoked or modified at any time 
upon a determination that the factual basis underlying the petition 
is incorrect, or DOE determines that the results from the alternate 
test procedure are unrepresentative of the basic models' true energy 
consumption characteristics.

Attachment D--Alternate Test Procedure for S&L Class Products 
(Established in S&L Class Waiver, Dec. 15, 2009)

    (A) MEUS shall be required to test the products listed in 
paragraph (2) above according to the test procedure for central air 
conditioners and heat pumps prescribed by DOE at 10 CFR Part 431 
(ARI 340/360-2004, incorporated by reference in 10 CFR 
431.95(b)(2)), except that MEUS shall test a ``tested combination'' 
selected in accordance with the provisions of subparagraph (B) of 
this paragraph. For every other system combination using the same 
outdoor unit as the tested combination, MEUS shall make 
representations concerning the S&L Class products covered in this 
waiver according to the provisions of subparagraph (C) below.
    (B) Tested combination. The term ``tested combination'' means a 
sample basic model comprised of units that are production units, or 
are representative of production units, of the basic model being 
tested. For the purposes of this waiver, the tested combination 
shall have the following features:
    (i) The basic model of a variable refrigerant flow system used 
as a tested combination shall consist an outdoor unit (an outdoor 
unit can include multiple outdoor units that have been manifolded 
into a single refrigeration system, with a specific model number) 
that is matched with between 2 and 8 indoor units in total; for 
multi-split systems, each of these indoor units shall be designed 
for individual operation.
    (ii) The indoor units shall--
    (a) Represent the highest sales model family, or another indoor 
model family if the highest sales model family does not provide 
sufficient capacity (see ii);
    (b) Together, have a nominal cooling capacity that is between 
95% and 105% of the nominal cooling capacity of the outdoor unit;
    (c) Not, individually, have a nominal cooling capacity that is 
greater than 50% of the nominal cooling capacity of the outdoor 
unit;
    (d) Operate at fan speeds that are consistent with the 
manufacturer's specifications; and
    (e) Be subject to the same mi
