MOTOR PRE-FILTER CLEANING AND MAINTENANCE
1. Make sure the filter pump is switched off, then disconnect the power cord from the electrical
outlet.
2. Turn both plunger valve handles fully clockwise until they stop. This closes the valve, prevents
the water from flowing out of the pool.
3. Release the pressure first by opening the sediment
release valve (19) located on the lower side of the
pre-filter housing (see drawing 34).
4. In a counter-clockwise motion unscrew the leaf trap
cover (14), then remove the basket (16) and leaf trap
o-ring (15) from the pre-filter housing (see drawing 35).
5. Empty and flush the basket using a garden hose, may
use a plastic brush to remove deposits from the basket.
Do not use metal brush.
6. Clean and rinse the inside of the pre-filter housing and
the leaf trap O-ring with a garden hose.
7. Reinstall the leaf trap O-ring, basket and leaf trap cover
to the pre-filter housing.
8. Close the sediment release valve (19) back.
FLOW SENSOR CLEANING
1. In a counter-clockwise motion unscrew the collar of the flow sensor (21) and remove it from
the electrolytic cell conduit (22). See "Part Reference".
2. If deposits and debris are seen on the surface of the flow sensor, then use a garden hose
to wash it off.
3. If flushing with water does not remove the deposits, use a plastic brush to clean the surface
and the hinge if necessary. Do not use a metal brush.
4. After the flow sensor has been inspected and cleaned, align the locator notch on the flow
sensor to the connection ridge in the conduit. Now turn the collar in a clockwise motion,
tightening the sensor back into its position. Do not overtighten.
