Current through Register Vol. 56, No. 23, December 2, 2024

Section 8:24-4.9 - Mechanical warewashing equipment

(a) 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; and

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

(b) 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) A warewashing machine shall be equipped with a temperature measuring device that indicates the temperature of the water:

1. In each wash and rinse tank; and

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

(d) A warewashing machine that uses a chemical for sanitization and that is installed after January 2, 2007, shall be equipped with a device that indicates audibly or visually when more chemical sanitizer needs to be added.

(e) 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, and if the flow pressure-measuring device is upstream of the fresh hot water sanitizing rinse control valve, the device shall be mounted in a one-fourth inch iron pipe size (IPS) valve.

1. This subsection does not apply to a machine that uses only a pumped or recirculated sanitizing rinse.

(f) Sinks and drainboards of warewashing sinks and machines shall be self-draining.

(g) A warewashing machine; the compartments of sinks, basins, or other receptacles used for washing and rinsing equipment, utensils, or raw foods, or laundering wiping cloths; and drainboards or other equipment used to substitute for drainboards shall be cleaned:

1. Before use;

2. Throughout the day at a frequency necessary to prevent recontamination of equipment and utensils and to ensure that the equipment performs its intended function; and

3. If used, at least every 24 hours.

(h) A warewashing machine and its auxiliary components shall be operated in accordance with the machine's data plate and other manufacturer's instructions. A warewashing machine's conveyor speed or automatic cycle times shall be maintained accurately timed in accordance with manufacturer's specifications.

(i) The temperature of the wash solution in spray type warewashers that use hot water to sanitize shall not be less than:

1. For a stationary rack, single temperature machine, 165 degrees Fahrenheit;

2. For a stationary rack, dual temperature machine, 150 degrees Fahrenheit;

3. For a single tank, conveyor, dual temperature machine, 160 degrees Fahrenheit; or

4. multitemperature machine, 150 degrees Fahrenheit.

(j) The temperature of the wash solution in spray-type warewashers that use chemicals to sanitize shall not be less than 120 degrees Fahrenheit.

(k) In a mechanical operation, the temperature of the fresh hot water sanitizing rinse as it enters the manifold may not be more than 194 degrees Fahrenheit, or less than:

1. For a stationary rack, single temperature machine, 165 degrees Fahrenheit; or

2. For all other machines, 180 degrees Fahrenheit.

(l) The flow pressure of the fresh hot water sanitizing rinse in a warewashing machine may not be less than 15 pounds per square inch or more than 25 pounds per square inch as measured in the water line immediately downstream or upstream from the fresh hot water sanitizing rinse control valve.

(m) Pressure measuring devices that display the pressures in the water supply line for the fresh hot water sanitizing rinse shall have increments of one pound per square inch or smaller and shall be accurate to +/- two pounds per square inch in the 15 to 25 pounds per square inch range.
