PREVENTIVE MAINTENANCE
OWC2412QC is 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 CON-
DENSATE 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.
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 assembly and check for obstructions. Clean as needed.
4. Clean the reservoir 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.
CLEANING THE UNIT
Wash all coils and filters and allow the unit to dry completely.
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.
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.
