§ 46.675. Mechanical warewashing equipment.
(a) Manufacturers’ operating instructions.
(1) A warewashing machine and its auxiliary components shall be operated in accordance with the machine’s data plate and other manufacturer’s instructions.
(2) A warewashing machine’s conveyor speed or automatic cycle times shall be maintained accurately timed in accordance with manufacturer’s specifications.
(b) Wash solution temperature where hot water is used to sanitize. The temperature of the wash solution in spray type warewashers that use hot water to sanitize may not be less than the following temperature, as applicable:
(1) For a stationary rack, single temperature machine, 74°C (165°F).
(2) For a stationary rack, dual temperature machine, 66°C (150°F).
(3) For a single tank, conveyor, dual temperature machine, 71°C (160°F).
(4) For a multitank, conveyor, multitemperature machine, 66°C (150°F).
(c) Wash solution temperature where chemicals are used to sanitize. The temperature of the wash solution in spray-type warewashers that use chemicals to sanitize may not be less than 49°C (120°F).
(d) Sanitizing rinse temperature where hot water is used to sanitize.
(1) Except as specified in paragraph (2), in a mechanical operation, the temperature of the fresh hot water sanitizing rinse as it enters the manifold may not be more than 90°C (194°F), or less than the following, as applicable:
(i) For a stationary rack, single temperature machine, 74°C (165°F).
(ii) For all other machines, 82°C (180°F).
(2) The maximum temperature specified in paragraph (1) does not apply to the high pressure and temperature systems with wand-type, hand-held, spraying devices used for the in-place cleaning and sanitizing of equipment such as meat saws.
(e) Sanitization pressure. The flow pressure of the fresh hot water sanitizing rinse in a warewashing machine may not be less than 100 kilopascals (15 pounds per square inch) or more than 170 kilopascals (25 pounds per square inch) as measured in the water line immediately downstream or upstream from the fresh hot water sanitizing rinse control valve.
