Initial startup and operation:
Before operating, be sure that:
• All the hoses have been connected and tightened securely, and correct amount of filter sand
have been loaded.
• The entire system is connected to a grounding type receptacle protected by a ground-fault
circuit interrupter (GFCI) or residual current device (RCD).
OPERATING INSTRUCTIONS (continued
)
CAUTION
The filter control valve has a closed position. The pump should never be on when the
valve is in the closed position. If the pump is operated with the valve closed, explosive
situation could exist.
1.
Turn both plunger valve handles fully counter-clockwise until they stop. This opens the valves
to allow water to flow into the sand filter pump.
NOTE:
The plunger valve is equipped with a vacuum release valve that will automatically
activate to minimize the suction at the pool outlet if the outlet is blocked. This is an additional
safety feature to prevent suction entrapment. The vacuum release valve will reset once the
blockage is removed and the pump is switched off. To restart the system the air must be
removed from the filter pump per previous step.
2.
Ensure the drain/waste outlet on the 6-way valve is not covered and directed to a proper
draining receptacle.
3.
Ensure the pump is off, depress the 6-way valve and turn it
to the “
BACKWASH
” position
(see drawings 24 & 29)
.
IMPORTANT: To prevent damage to the 6-way valve,
always depress the valve handle before turning. Always
switch off pump before changing the 6-way valve
position.
4.
Switch on the pump
(see drawing 30)
. Water is circulating
backward through the sand media and to waste/drain outlet.
Backwash until a clear flow of water is observed in the waste/
drain outlet or through the transparent outlet adaptor.
NOTE:
The initial backwash of the filter is recommended to
remove any impurities or fine sand particles in the sand
media.
