Preventive Maintenance - OCEANAIRE OWC Series Engineering, Installation And Service Manual

PREVENTIVE MAINTENANCE

OWCs 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:
OFF SEASON STORAGE—WINTERIZATION
Before placing the unit into storage for the off-season, it is recommended to thoroughly
clean the unit, and remove all water in the CONDENSER COIL, WATER LINES, DRAIN PAN
and CONDENSATE PUMP to avoid damage to the unit from freezing water or
contamination.
DRAINING THE CONDENSER COIL, AND INTERIOR WATER LINES
To drain the condenser coil, detach the WATER IN and WATER OUT lines. Using a
Shop-Vac or similar devise, vacuum the WATER OUT line and start the unit. The water
valve will open, allowing you to vacuum the water out of the condenser coil. Eventually,
the High Pressure Cut-Out will shut down the compressor. Wait 15 minutes, depress the
HI PRESSURE RESET and repeat this process until ALL of the water is out of the system.
When completed, depress the HIGH PRESSURE RESET one final time to make sure that it
is reset.
BLOWER MOTOR
The evaporator motor on all units have permanently lubricated bearings. No oiling is
necessary
FILTER
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 filter must be washed periodically as needed
by placing it in a dishwasher or soaking in a solution of warm water and detergent for 10
minutes. Then rinsing clean with hot water and shaking excess moisture from filter.
DRAINING THE HOSE KIT
To drain the hose kit, disconnect all hoses, and allow the hoses to gravity drain.
EVACUATING THE CONDENSATE PUMP
Using a Shop-Vac or similar device, vacuum all water out of the condensate pump
reservoir. Condensate pumps come standard on all OWC 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. Clean as needed.
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 inhibit flow.
GENERAL
Oceanaire products are NOT approved for outdoor use. Therefore, off-season storage
should be indoor, protected from weather conditions.
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.
