CHAPTER 4: PREVENTIVE MAINTENANCE

4.1Daily Checks and Services

Inspect Rethermalizer and Accessories for Damage

Look for loose or frayed wires and cords, leaks, foreign material in cookpot or inside cabinet, and any other indications that the rethermalizer and accessories are not ready and safe for operation.

Clean Cabinet Inside and Out

Clean inside the cabinet with a dry, clean cloth. Wipe all accessible metal surfaces and components to remove accumulations of oil, dust, or cooking residue.

Clean the outside of the cabinet with a clean cloth dampened with dishwashing detergent, removing oil, dust, or cooking residue.

DANGER

Never attempt to clean rethermalizer during the rethermalizing process or when the cookpot is filled with hot water and/or food products.

Clean Water-Level Sensors, Temperature Probe, and Cookpot

Press the controller power switch to the OFF position.

FBRA18 Units: Remove the cap nut at the top of the shield (located on the left front of the cook- pot) and remove the shield by lifting up until it can be removed from the stud that holds it at the bottom. Clean the exposed screw heads with a solution of detergent and water. A Scotchbrite™ or equivalent nylon pad may be used to scrub away any accumulated mineral deposits.

FBR18 & FBRA18 Units: Clean the temperature probe, located on the lower front centerline of the cookpot, using a small bottlebrush wet with a solution of detergent and water.

Using a Scotchbrite™ or similar abrasive pad and a solution of detergent and water, clean the inside of the cookpot.

Rinse the cookpot thoroughly with clean water at least twice.

4.2Quarterly Checks and Services

Check Digital Controller Set Point Accuracy

1.Fill the cookpot with water. Press the controller power switch. When the Heat Mode indicator (decimal between the first and second digits of the display) goes out, insert a good-grade thermometer or pyrometer probe into the cookpot, with the end touching the temperature probe at the lower front centerline of the cookpot and wait one minute.
