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. If cleaner containing chlorides are used be sure to rinse
repeatedly and dry thoroughly upon completion.
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 steels protective layer.
Never use and acid based cleaning solution! Many food products have an acidic
content which can deteriorate the finish. Be sure to clean the ALL food products
from any stainless steel surface. Common items include peppers, tomatoes and
other vegetables.

Cleaning the Condenser Coil
Disconnect machine. 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
failures.
To put back the condensing unit in its place, slide in the unit carefully. BE
SURE DRAIN PIPE IS LOCATED OVER THE PAN. Replace front bottom panel
4.2.2
Cleaning the Gasket
Gaskets require regular cleaning to prevent mold and mildew build up and
also to keep the elasticity of the gasket. Gasket cleaning can be done with
the use of warm soapy water. Avoid full strength cleaning products on
gaskets as this can cause them to become brittle and prevent proper seals.
Also, never use sharp tools or knives to scrape or clean the gasket which
could possibly tear the gasket and rip the bellows.
Gaskets can easily be replaced and do not require the use of tools or
authorized service persons.
The gaskets can be pulled out of the grove in the door and new gaskets can
be “pressed” back into place.
