PREVENTIVE MAINTENANCE
PWC’s 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 com-
pleted, depress the HIGH PRESSURE RESET one final time to make sure that
it is reset.
DRAINING THE HOSE KIT
To drain, disconnect all three 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 PWC 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.
