MAINTENANCE
Stainless Steel Care and Cleaning
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 or non-chloride cleaners. Any cleaner containing chlorides
will damage the protective film of the stainless steel. Chlorides are commonly found in hard water,
salts, house hold and industrial cleaners. If a cleaner containing chloride is used, be sure to rinse
repeatedly and dry thoroughly up on completion.
Stainless steel m u s t b e c l e a n e d e v e r y d a y with soap and water. Extreme stains or grease
should be cleaned with a non-abrasive cleaner and plastic scrub pad. When using a stainless steel
chemical cleaner, make sure it is recommended for commercial applications.
Never use an acid based cleaning solution! Many food products have an acidic content which can
deteriorate the stainless steel finish. Be sure to clean ALL food products from any stainless steel
surface. Failure to do so, will result in spots and rust on the surface affected.

CLEANING THE CONDENSER COIL
DANGER: Power must be turned off and disconnected from the power source whenever
performing maintenance, repair or cleaning the condensing unit.
Disconnect machine. Remove front bottom panel and carefully slide out the condensing unit.
The condenser coil requires regular cleaning. I t i s recommended every 30-60 days, depending on
the accumulation of dust and grease.
If the build upon the coil consists of only light dust and debris, the condenser coil can be cleaned
with a simple brush. Heavier dust build up may require a vacuum or even compressed air to blow
though the condenser coil.
If heavy grease is present, there are de-greasing agents available for coils. The condenser
coil may require to be sprayed with de-greasing agent and then to be dried with
compressed air.
Be sure all electrical and mechanical parts are dry before turning ON the
power.
Never use high pressure water for cleaning t h e c o n d e n s e r c o i l . Water can damage the
electrical components located near or at the condenser coil. Do not place filter material in front of
condenser coil. This material blocks air-flow to the coil similar to having a dirty coil!
