Depress top mount valve handle and rotate to BACKWASH position.

Prime and start pump according to pump instructions.

NOTE: ALL SUCTION AND DISCHARGE VALVES MUST BE OPENING WHEN

STARTING THE SYSTEM. FAILURE TO DO SO COULD CAUSE SEVERE PERSONAL

INJURY.

MAKE SURE THE FILTER VESSEL ARE FULL FILL THE WATER BEFORE START

UP THE PUMP. OR IT WILL CAUSE THE PUMP DAMAGED.

Once water flow is steady out the waste line, run the pump for at least 2 minutes. The initial

back-washing of the filer is recommended to remove any impurities of fine sand particles in the

sand media.

Turn pump off and set valve to RINSE position. Start pump and operate until water in sight

glass is clear----about 1/2 to 1 minute. Turn pump off, set valve to FILTER position and restart

pump. Your filter is now operating in the normal filter mode, filtering particles from the pool

water.

NOTES:

Note the initial pressure gauge reading when the filter is clean. (It will vary from pool

depending upon the pump and general piping system). As the filter removes dirt and impurities

from the pool water, the accumulation in the filter will cause the pressure to rise and flow to

diminish. When the pressure gauge reading is 8-10 PSI(0.55-0.69 BAR) higher than the initial

!clean" pressure you noted, it is the time to backwash (clean) the filter.

IMPORTANT: To prevent unnecessary strain on piping system and valving, always shut off

pump before switching filter control valve position.

To prevent damage to the pump and filter and for proper operation of the system, clean pump

strainer and skimmer baskets regularly.

FILTER CONTROL VALVE FUNCTIONS

Filter-

FILTER - Set valve to FILTER for normal filtering. Also use for regular vacuuming.

Backwash-

BACKWASH $ For cleaning filter. When filter pressure gauge rises 8-10 PSI (0.55-0.69 BAR)

above start-up (clean pressure):

Stop the pump, set valve to BACKWASH. Start pump and backwash until water in sight glass is

clear. Approximately 2 minutes or less depending on dirt accumulation. Proceed to RINSE.

Rinse-

RINSE $ After backwashing, with pump off, set valve to RINSE. Start pump and operate for about

1/2 to 1 minute. This ensures that all dirty water from backwashing is rinsed out of the filter to waste,

preventing possible return to the pool. Stop pump, set valve to FILTER and start pump for normal

filtering.

Waste-

WASTE $ To bypass filter for draining or lowering water level and for vacuuming heavy debris

directly to waste.

Re circulate-

RECIRCULATE: Water is recirculated through the pool system, bypassing the filter.

Closed-

CLOSED $ Shuts off flow from pump to filter.
