Preventive Maintenance - OCEANAIRE 2OACH Series Engineering, Installation And Service Manual

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.
