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. Grasp a plunger valve handle. Turn the handle counter-clockwise, push down
until it stops and then turn it clockwise until the plastic protruding notch anchors
in the "0/1" position. Repeat for the second plunger valve. This prevents the
water from flowing out of the pool.
3. Release the pressure first by opening the sediment release valve (22) located
on the lower side of the pre-filter housing (see drawing 38).
4. In a counter-clockwise motion unscrew the leaf trap cover (17), then remove the
basket (19) and leaf trap o-ring (18) from the pre-filter housing (see drawing 39).
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 (22) back.
If the pool water is hard (high mineral content) the cell may require periodic manual
cleaning. To maintain maximum performance, we recommend that you open and
visually inspect the electrolytic cell (10) once every month.
The following steps are some instructions on how to clean your cell.
1. Switch off the unit, unplug the power cord from the electrical socket.
2. Disconnect the hose (25) from the electrolytic cell (10) outlet and cover the
outlet with the drain outlet cover (3) from the 6-way valve (see drawings 40
and 41).
3. Remove the electrolytic cell from the 6-way valve outlet by unscrewing the
electrolytic cell (10) collar (see drawing 42).
4. Pour kitchen grade vinegar into the cell to immerse the titanium plates (see
drawing 43). Soak for about 1 hour and then flush with a high-pressure
garden hose.
5. Reverse steps 2 to 4 to reconnect the electrolytic cell.
