OPERATION
Be sure lter drain plug is closed.
1. Open manual air relief valve a few turns and open the suction and return valves (when
used). CAUTION: All suction and discharge valves must be open when starting the system.
Failure to do so could cause severe personal injury and/or property damage. Be sure locking knob is secure
(hand tighten--only slight preissure is required).
2. Stand clear of the lter and prime and start the pump, following the manufacturer’s instructions. Air trapped
in the system will automatically vent to the pool and out air relief valve. Close air relief valve as soon as air
is vented.
CLEAN/REPLACE FILTER BALLS
Filtration starts as soon as ow is steady through the lter.
As the lter cartridge removes dirt from the pool water, the
accumulated dirt causes a resistance to ow. As a result,
the gauge pressure will rise and the ow will decrease.
When the pressure rises 7-10 psi (.49-.70 Bar) above the
starting pressure, or when ow decreases below desired
rate, clean or replace the lter cartridge.
