Maintenance Section 4
REFRIGERATOR
n
Warning
Do not damage the refrigeration circuit when installing,
maintaining or servicing the unit.
The interior and exterior can be cleaned using soap and
warm water. If this isn’t sufficient, try ammonia and water
or a nonabrasive liquid cleaner. When cleaning the exterior,
always rub with the “grain” of the stainless steel to avoid
marring the finish. Do not use an abrasive cleaner because
it will scratch the stainless steel and can damage the
breaker strips and gaskets.
STAINLESS STEEL CARE & 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 break down the steel and begin to
form discoloration or rust. Proper cleaning of stainless steel
requires soft cloths or plastic scouring pads!
n
Warning
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 steel’s 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.

Caution
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.
DOORS/HINGES
Over time and with heavy use, doors and hinges may
become loose. If this happens, tighten the screws that
mount the hinge brackets to the frame of the unit. Loose
or sagging doors can cause the hinges to pull out of the
frame, which may damage both the doors and the hinges.
In some cases this may require qualified service agents or
maintenance personnel to perform repairs.
NOTE: Do not place hot pans on/against the blue ABS liner.
Do not throw items into the storage area. Failure to follow
these recommendations could result in damage to the
interior of the cabinet or to the blower coil. Overloading
the storage area, restricting the airflow, and continuous
opening and closing of the doors and drawers will hamper
the unit’s ability to maintain operational temperature.
PREVENTING BLOWER COIL CORROSION
Immediately wipe up all spills.
