MAINTENANCE
DANGER:
THE UNIT MUST BE TURNED OFF AND DISCONNECTED FROM THE POWER
SOURCE WHENEVER PERFORMING SERVICE, MAINTENANCE FUNCTIONS OR
CLEANING THE REFRIGERATED AREA.
DANGER:
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.
DANGER:
NEVER USE STEEL PADS, WIRE BRUSHES OR SCRAPERS!
CAUTION: NEVER USE AN ACID BASED CLEANING SOLUTION！MANY FOOD PRODUCTS
HAVE AN ACIDIC CONTENT WHICH CAN DETERIORATE THE FINISH. BE SURE
TO CLEAN THE STAINLESS STEEL SURFACES OF ALL FOOD PRODUCTS.
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 and it is recommended 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
cleaning 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.
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
