Caster Maintenance
Wipe casters with a damp cloth monthly to prevent corrosion.
The power switch must be turned to OFF and the
unit disconnected from the power source whenever
performing service, maintenance functions or cleaning
the refrigerated area.
Stainless Steel Care and Cleaning
To prevent discoloration or rust on stainless steel several important
steps need to be taken. First, we need to understand the properties
of stainless steel. Stainless steel contains 70- 80% iron, which will
rust. It also contains 12-30% chromium, which forms an invisible
passive film over the steel’s surface, which acts as a shield against
corrosion. As long as the protective layer is intact, the metal is still
stainless. If the film is broken or contaminated, outside elements
can begin to breakdown the steel and begin to form discoloration or
rust. Proper cleaning of stainless steel requires soft cloths or plastic
scouring pads.
NEVER USE STEEL PADS, WIRE BRUSHES OR SCRAPERS!
Cleaning solutions need to be alkaline based or non-chloride
cleaners. Any cleaner containing chlorides will damage the protective
film of the stainless steel. Chlorides are also commonly found in
hard water, salts, and household and industrial cleaners. If cleaners
containing chlorides are used be sure to rinse repeatedly and dry
thoroughly. Routine cleaning of stainless steel can be done with
soap and water. Extreme stains or grease should be cleaned with
a non-abrasive cleaner and plastic scrub pad. Always rub with the
grain of the steel. There are stainless steel cleaners available which
can restore and preserve the finish of the steels protective layer.
Early signs of stainless steel breakdown are small pits and cracks.
If this has begun, clean thoroughly and start to apply stainless steel
cleaners in attempt to restore the passivity of the steel.
Never use an acid based cleaning solution! Many food
products have an acidic content, which can deteriorate the
finish. Be sure to clean the stainless steel surfaces of ALL
food products. Common items include, tomatoes, peppers
and other vegetables.
Units with pans should be operated with pans in place.
Operating the unit without all pans in place will lower
efficiency and may damage the unit.
Plexiglas Food Shield Cleaning
Wet a clean cloth with lukewarm water and dishwashing liquid.
Apply only light pressure, rinse with clear and blot dry with a damp
chamois. For excessively dirty surfaces, rinse surface dirt off before
washing. Fine scratches will disappear when you polish by hand with
a plastic cleaner polish.
Never use window sprays, kitchen scouring compounds
or solvents such as acetone, gasoline, benzene, alcohol,
carbon tetrachloride or lacquer thinner to clean plexiglas.
