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
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.
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 drain sediment
window.
NOTE:
The initial backwash of the filter is
recommended to remove any impurities or fine
sand particles in the sand media.
