PREVENTIVE MAINTENANCE
Cleaning the Condenser Coil
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 compres-
sor failure. Neglecting the condenser coil
cleaning procedures will void all warranties and
repair or replacement costs associated with the
compressor.
CAUTION: To clean the condenser, never use
a high-pressure water wash, which
can damage electrical components
located at or near the condenser
coil.
Figure 2
Location of Condensing Coil
and Air Filter
The condenser coil is located and accessed at
the rear of the unit (see Figure 2). The condenser
coil requires regular cleaning and should be done
every 60 days. However, if large amounts of
dust and grease accumulate sooner, clean the
condenser coil every 30 days.
For light dust, use a soft, non-wire brush.
For heavier dust, use a vacuum or blow with
compressed air.
For heavy grease, use a degreasing agent made
specifically for condenser coils on refrigeration
units. Spray the degreasing agent on the coil
and then blow with compressed air. Never wash
with high-pressure water, which can damage
the electrical components located at or near the
condenser coil.
Door Gasket Maintenance
Door gaskets require regular cleaning to prevent
mold and mildew build up and to maintain
elasticity for proper seal function. Warm soapy
water is adequate for cleaning the gasket. Avoid
using full strength cleaning products, which can
cause the gasket to become brittle and result in
improper seal function. Never scrape or clean the
gasket with sharp tools or knives.
