MAINTENANCE – Cleaning the Condenser Coil – cont.
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 condensor coil.
If heavy grease is present degreasing agents are available for refrigeration use and specifically
for the condenser coils. The condenser coil may require a spray with the degreasing 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.
CAUTION:
NEVER USE A HIGH-PRESSURE WATER WASH FOR THIS CLEANING PROCEDURE AS WATER CAN
DAMAGE ELECTRICAL COMPONENTS LOCATED NEAR OR AT THE CONDENSER COIL.
MAINTENANCE – Door Care
The door track needs to remain clear of debris to enable doors to close freely. If the doors can’t
seal properly, internal temperatures are at risk of not being properly controlled. Debris in tracks
can be wiped or vacuumed out. Warm soapy water can be used for cleaning.
MAINTENANCE – Drain
Each unit has a drain tube located in the rear the unit which removes condensation from the
evaporator coil and deposits it onto a drain pan where it can evaporate. If you notice excessive
water accumulation on the inside of the unit be sure that the drain tube is connected from the
evaporator housing to the condensate evaporator drain pan. If water is collecting underneath
the unit you may want to check the condensate evaporator drain tube to be sure it is still
located above the drain pan. The leveling of the unit is also important as the units are designed
to drain properly when on a level surface, if your floor is not level this can also cause drain
problems. Be sure the drain pan is kept free of dirt, dust and other debris as excessive amounts
will cause water to back up and overflow from the drain pan.
MAINTENANCE – Drain Pan Access
The drain pan and drain tube can be accessed from the top, rear area of the unit. Remove the
top rear cover. The drain pan is located behind this cover.
