Hazardous pressure. To avoid explosion and possible
severe or fatal injury, filter system pressure must not exceed stated
filter system with compressed air; never operate system with water
temperature above 95°(35° C).
To prevent equipment damage and possible injury, turn
pump OFF before changing valve position.
NOTICE:
Do not add chemicals directly into the pool skimmer. Adding
undiluted chemicals may damage equipment and void warranty.
1. Open system valves and make sure pump is filled with water. Make
sure pool water level is 2” (51mm) above bottom of skimmer open-
ing.
2. With pump OFF, set valve to ‘BACKWASH’ position.
3. Start pump, circulating water backwards through filter to waste. Do
not install pressure gauge until a steady stream of water runs out of
gauge port; then stop pump and install gauge.
NOTICE:
T
o prevent pump from running dry, be sure water level
never drops below bottom of skimmer inlet. Add water to pool if
necessary to keep skimmer flooded while backwashing and rinsing.
