MAINTENANCE

The power switch must be turned to OFF and the unit disconnected 

from the power source whenever performing service, maintenance 

functions or cleaning the refrigerated area.

REFRIGERATORS AND FREEZERS

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 plastic and can damage 
the breaker strips and gaskets 

CLEANING THE CONDENSER COIL

The condenser coil requires regular cleaning at least 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 every 30 days 

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 even 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 the 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.

In  order  to  maintain  proper  refrigeration  performance,  the  condenser  fins  must  be  cleaned  of 
dust, dirt and grease regularly  It is recommended that this be done at least every three months  If 
conditions are such that the condenser is totally blocked in three months, the frequency of cleaning 
should be increased  Clean the condenser with a vacuum cleaner or stiff brush  If extremely dirty, a 
commercially available condenser cleaner may be required 

STAINLESS STEEL CARE AND CLEANING

To prevent discoloration of rust on stainless steel, several important steps need to be taken  First, it is 
important 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 breakdown the steel 
and begin to form rust or discoloration 

Proper cleaning of stainless steel requires soft cloths or plastic 

scouring pads. NEVER USE STEEL PADS, WIRE BRUSHES OR SCRAPERS!
