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. Release air from the system -
Ensure the drain/waste outlet
on the 6-way valve is not covered and directed to a proper
draining receptacle, and the pump is off. Turn the 6-way
valve to the “N” position and unscrew the air release valve
(36)
from the motor housing
(see drawing 29)
. When water
starts flowing out of the air release valve hole, close the air
release valve back.

to the “

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.
