MAINTENANCE
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.
NEVER USE STEEL PADS, WIRE BRUSHES OR SCRAPERS!
DANGER!
DANGER!
Cleaning the Condenser Coil:
The condenser coil requires regular cleaning, and 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.
Stainless Steel Care and Cleaning:
To prevent discoloration of rust on stainless steel, several important steps need to be taken. First,
we need 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
steels 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 of discoloration.
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
commercial-grade condenser cleaner may be required.
Proper cleaning of stainless steel requires soft cloths or plastic scouring pads.
