§ 46.591. Warewashing machines.

 (a)  Data plate summarizing operating specifications. A warewashing machine shall be provided with an easily accessible and readable data plate affixed to the machine by the manufacturer that indicates the machine’s design and operating specifications, including the following:

   (1)  Temperatures required for washing, rinsing and sanitizing.

   (2)  Pressure required for the fresh water sanitizing rinse unless the machine is designed to use only a pumped sanitizing rinse.

   (3)  Conveyor speed for conveyor machines or cycle time for stationary rack machines.

 (b)  Internal baffles. Warewashing machine wash and rinse tanks shall be equipped with baffles, curtains or other means to minimize internal cross contamination of the solutions in wash and rinse tanks.

 (c)  Temperature measuring devices. A warewashing machine shall be equipped with a temperature measuring device that indicates the temperature in the following locations or instances:

   (1)  In each wash and rinse tank.

   (2)  As the water enters the hot water sanitizing final rinse manifold or in the chemical sanitizing solution tank.

 (d)  Detergent and sanitizer level indicator. A warewashing machine that is installed after December 13, 2003, shall be designed and equipped to automatically dispense detergents and sanitizers and incorporate a visual means to verify that detergents and sanitizers are delivered or a visual or audible alarm to signal if the detergents and sanitizers are not delivered to the respective washing and sanitizing cycles.

 (e)  Flow pressure device. Warewashing machines that provide a fresh hot water sanitizing rinse shall be equipped with a pressure gauge or similar device such as a transducer that measures and displays the water pressure in the supply line immediately before entering the warewashing machine. If the flow pressure measuring device is upstream of the fresh hot water sanitizing rinsecontrol valve, the device shall be mounted in a 6.4 millimeter or 1/4 inch Iron Pipe Size valve. This subsection does not apply to a machine that uses only a pumped or recirculated sanitizing rinse.
