Initial startup and operation:
Before operating, be sure that:
• All the hoses have been connected and tightened securely, and correct amount
of filter sand has 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).
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, an explosive situation could exist.
1. Grasp a plunger valve handle. Turn the handle counter-clockwise, pull up until it
stops, and then turn it clockwise until the metal protruding notch anchor is in
the "0/1" position. Repeat for the second plunger valve. 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 is 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 31 & 36).
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 37). 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.
