PREVENTIVE MAINTENANCE
2OACH Heat Pumps are designed to last a long time and to give maximum performance
and reliability with minimum maintenance. To prolong the life of the unit, regular
maintenance must be performed as specified below:
BLOWER MOTORS
The motors on all units have permanently lubricated bearings. No oiling is
necessary
FILTERS
A clogged filter will cause the unit to operate at greatly reduced efficiencies. We
recommend that the filter be inspected on a regular basis every six weeks or less,
depending on the environment. The evaporator filter is located behind the return air grille
and can be easily removed and cleaned. The condenser filter is located on the backside
of the unit. The filters must be washed periodically as needed by placing them in a
dishwasher or soaking them in a solution of warm water and detergent for 10 minutes.
Then rinsing them clean with hot water and shaking excess moisture from filter.
CONDENSATE PUMP
Condensate pumps come standard on all Size 60 models, and may be installed as
options on size 12, 18, 24 and 36 models. When servicing pump follow these steps;
1. Make certain that the unit is disconnected from the power source before attempting to
service or remove any component.
2. Be sure the floats move freely. Clean as necessary.
3. Remove the pump housing and check for obstructions.
4. Clean the housing with warm water and mild soap when mineral deposits are visible.
5. Check the inlet and outlet piping. Clean as necessary. Be sure there are no kinks in the
lines that would restrict flow.
GENERAL
When necessary maintenance steps outlined above are followed, the air conditioner will
provide long and reliable service. The refrigeration and electrical circuits of the system
should only be serviced by a fully qualified service technician.
