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, and 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 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 28 & 33).
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 34). 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.
