HOW TO USE
1． Inspect all the connections have been made correct and are secure.
2． Depress top mount valve handle and rotate to BACKWASH position.
3． 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.
FILTER VESSEL ARE FULLY FILLED THE WATER BEFORE STARTING UP THE PUMP OR IT WILL
CAUSE THE PUMP DAMAGED.
4． 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.
5． 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:
1． 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 higher than the initial "clean" pressure you noted, it is the time to backwash (clean) the
filter.
2． IMPORTANT: To prevent unnecessary strain on piping system and valving, always shut off pump before
switching filter control valve position.
3． 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 - Set valve to FILTER for normal filtering. Also use for regular vacuuming.
BACKWASH – For cleaning filter. When filter pressure gauge rises 8-10 PSI 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 – 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 – To bypass filter for draining or lowering water level and for vacuuming heavy debris directly to waste.
