3. Replace filter coping (with O'ring in place).
a. Carefully screw pressure gauge (with O'ring in place) into tapped hole in the filter coping. Do not over-tighten.
b. Ensure air relief valve (with O'ring in place) is tight fit to filter coping and turn it easily.
4. Connect pump to control valve opening marked PUMP.
5. Make return to pool pipe connection to control valve opening marked RETURN and complete other necessary plumbing
connections, suction lines to pump, waste, etc.
6. Make electrical connections to pump per pump instructions.
7. To prevent water leakage, be sure all pipe connections are tight.

1. Be sure correct amount of filter media sand is in tank and that all connections have been made and are secure.
2. Depress control valve handle and rotate to BACKWASH position. (To prevent damage to control valve seal,always depress
handle before turning.)
3. Prime and start pump according to pump instructions (be sure all suction and return lines are open), allowing the filter tank to
fill with water. Once water is flowing out of the waste line, run the pump for at least 1 minute. The initial back-washing of the
filter is recommended to remove any impurities or fine sand particles in the sand media.
4. 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 and set valve to FILTER position and restart pump.The filter is now operating in the normal filter mode,
filtering dirt particles from the pool water.
5. Adjust pool suction and return valves to achieve desired flow. Check system and filter for water leaks and tighten
connections, bolts, nuts, as required.
6. Note the initial pressure gauge reading when the filter is clean. (It will vary from pool to 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 1.5 bar, higher than the initial "clean" pressure
you noted, it is time to backwash the filter (see BACKWASH under filter and control valve functions).
NOTE: During initial clean-up of the pool water it may be necessary to backwash frequently due to the unusually

heavy initial dirt load in the water.
