3.1 General safety rules
Neglecting the condenser coil cleaning procedures WILL VOID YOUR WARRANTY
associated with the compressor or cost to replace the compressor!
To prevent corrosion and damage to stainless steel surfaces, use only products
formulated for use on stainless steel appliances. Do not use steel wool, abrasive
products, scrapers, or products containing sodium hypochlorite (chlorine bleach). Use a
clean, soft cloth for cleaning.
3.2 Machine cleaning and maintenance routine
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 also
commonly found in hard water, salts, and household and industrial cleaners.
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. There are
also stainless steel cleaners available which can restore and preserve the finish of the
steel
’s protective layer.
Never use an acid based cleaning solution! Many food products have an acidic content
which can deteriorate the finish. Be sure to clean ALL food products from any stainless
steel surface. Common items include peppers, tomatoes and other vegetables
.
3.2.1 Cleaning the Condenser Coil
Move the power switch to the “OFF” position, then unplug appliance, remove front
bottom panel and carefully slide out the condensing unit. The condenser coil requires
regular cleaning; recommended every 30-60 days, depending of the accumulation of
dust and grease. If the buildup on 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 refrigeration use and specifically for
the condenser coils. The condenser coil may require a spray with the de-greasing agent
and then blown through with compressed air.
Be sure all electrical and mechanical parts are dry before turning on the power. Never
use a high pressure water wash for this cleaning procedure as 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!
If you keep the Condenser clean you will minimize your service expense and lower your
electrical costs. Failure to maintain a clean condenser coil can initially cause high
temperatures and excessive run times. Continuous operation with dirty or clogged
condenser coils can result in compressor failure.
