GENERAL MAINTENANCE
Stainless Steel Care and Cleaning
To prevent discoloration or rust on stainless steel 
several important steps need to be taken. First, the 
properties of stainless steel need to be understood. 
Stainless steel contains 70-80% iron that will rust. It 
also contains 12-30% chromium that forms an invisible 
passive film over the steel’s surface and acts as a 
shield against corrosion. As long as the protective 
layer is intact, the metal will not corrode, 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 rust or other discoloration.
Never use steel pads, wire brushes or scrapers!
Do not use an abrasive cleaner because it will scratch 
the stainless steel and plastic and can damage 
the breaker strips and gaskets. Proper cleaning of 
stainless steel requires soft cloths or plastic scouring 
pads.
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 upon completion.
Routine cleaning of the interior and exterior can be 
done with soap and warm water. Extreme stains or 
grease should be cleaned with a non-abrasive cleaner 
and plastic scrub pad. When cleaning the exterior, 
always rub with the grain of the stainless steel to 
avoid marring the finish. There are also stainless steel 
cleaners available which can restore and preserve the 
finish of the steels protective layer.
Early signs of stainless steel breakdown can consist 
of 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 that can deteriorate 
the finish. Be sure to clean ALL food products from 
any stainless steel surface. Common items include, 
tomatoes, peppers and other vegetables.
Cleaning the Condenser Coil
The condenser coil requires regular cleaning, 
recommended is every 90 days. In some instances 
you may find that there is a large amount of debris and 
dust or grease accumulated prior to the 90-day time 
frame. In these cases the condenser coil should be 
cleaned as needed.
If the build up 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 
compressed air to blow through 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.
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. Neglecting 
condenser coil cleaning procedures will void any 
warranties associated with the compressor or cost to 
replace the compressor.
 
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.
If your freezer seems to vibrate excessively when the 
compressor is running, loosen (but do not remove) the 
bolts on the compressor. Semi hermetic models should 
be loosened before operating.
