Daily Checks and Services
Inspect Cooking System 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.
Never attempt to clean this equipment during the rethermalizing/cooking process or
when the cookpot is filled with hot water and/or food products.
Clean Float Switch Assemblies, Vat

similar abrasive pad and a solution of detergent and
warm water, clean the inside of the vat, paying
particular attention to the elements.
Rinse the vat thoroughly with clean water at least twice.
