Disconnect unit from power supply. Open access door to expose condensing unit. The condenser
coil requires regular cleaning; recommended is every 30 – 60 days, depending on the accumulation
of dust and grease.
If the buildup 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
though 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 a spray with the de-greasing
agent and then blown through with compressed air. Be sure all electrical and mechanical parts are
dry before turning on the power. 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! Do not
place filter material in front of condenser coil. This material blocks air-flow to the coil similar to
having a dirty coil!
If you keep the condenser clean you will minimize your service expense and lower your electrical
costs. 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 YOUR WARRANTY associated with
the compressor or cost to replace the compressor!
6.3 DRAIN MAINTENANCE
Each unit has a drain located inside the unit which removes the condensation from the evaporator
coil and evaporates it at an external condensate evaporator pan. Each drain can become
loose or disconnected from moving or bumping the drain. IF YOU NOTICE EXCESSIVE WATER
ACCUMULATION ON THE INSIDE OF THE UNIT be sure the drain tube is connected from the
evaporator housing to the condensate evaporator drain pan.
IF WATER IS COLLECTED UNDERNEATH THE UNIT you may want to check the condensate
evaporator drain tube to be sure it is still located inside the drain pan. The leveling of the unit is
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 all drain lines are free of obstructions; typically
food products are found blocking drain lines causing water to back up and overflow the drain pan.
6.2 CLEANING THE CONDENSOR COILS
DANGER
Power must be turned off and disconnected from the power source whenever performing
maintenance, repair or cleaning the condensing unit.
