CLEANING THE CONDENSER COIL
WARNING
THE POWER MUST BE TURNED OFF
AND DISCONNECTED AT ALL TIMES
DURING MAINTENANCE OR REPAIR
FUNCTIONS.
Failure to maintain a clean condenser coil can
cause high temperatures and excessive run
times. Continuous operation with dirty or clogged
condenser coils can result in compressor failure.
Neglecting the condenser coil cleaning procedures
will void the compressor warranty.
CAUTION: Never use high-pressure water
to clean the condenser. High-
pressure water can damage
electrical components located at
or near the condenser coil.
Condenser Coil Vent Cover Removed
The condenser coil is located in and accessed
to the front of the unit. A vent cover protects the
condenser from damage. The condenser coil
requires regular cleaning and should be done
every 60 days. However, if large amounts of dust
and grease accumulate more often, clean the
condenser coil every 30 days. For light dust, use
a soft, non-wire brush. For heavier dust, use a
vacuum cleaner or blow with compressed air.
For heavy grease, use a degreasing agent made
specifi cally for condenser coils on refrigeration
units. Spray the degreasing agent on the coil and
then blow with compressed air. Never wash the
condenser with high-pressure water. High pressure
water can damage or bend the cooling fi ns on the
condenser, reducing its effi ciency.
Water can also damage the electrical components
located near the condenser coil.
