Each water supply system in a facility, must maintain one part per million free residual chlorine at remote point-of-use fixtures in the facility or the facility may use another bacteriological control method that has been demonstrated to be equivalent in control of Legionella. Increasing the water temperature range from one hundred twenty-two degrees to one hundred twenty-five degrees Fahrenheit or fifty degrees to fifty-two degrees centigrade is acceptable for the control Legionella. The facility shall document water temperatures to verify the hot water temperature is being maintained within the acceptable range for the control Legionella. If hot water temperatures are outside the acceptable range, the facility must conduct chlorine testing using photocell and light source N, N, Diethyl-p-phenylenediamine test kits, and the facility shall log the test results. If testing demonstrates that consistent chlorine levels are maintained, the facility may conduct monthly testing.
