Make yourself familiar with your filter system’s valve settings and functions.
Filter Valve Settings & Functions
Setting Complete Water Flow/Function
Filtration Regular pool filter action. This is the setting the filter will be set to most of the time. In this position, water is directed
through the top of the filter where it compresses and flattens the sand. Contaminants are trapped by the sand as water
makes it way to the bottom strainer, out of the filter and back to the pool.
Rinse Rinse for no longer than 60 seconds right after backwashing to clean and resettle filter bed. This should always be done
immediately after backwashing, new sand addition or filter start-up. In this position, water is directed to the top of the
tank where it reseats the sand and flushes the valve while sending water out of the waste line. This reduces the chance
of contaminant blow back to the pool when the valve is switched back to the filtration setting after backwashing. Run.
Backwash Clean filter of captured debris. This is the position needed to clean the filter and sand. You’ll know it is time to backwash
when the pressure gauge rises (5 - 10 psi) above its normal readings (2 - 10 psi) when the filter is clean. In this position,
water is directed through the bottom strainer, reversing the flow through the tank. This causes the sand to separate
and lift while releasing trapped debris out the waste line.
Winterize/
Drain
Bypass the filter. In this position, water bypasses the filter and sends all the water and contaminants out of the waste
line.
CAUTION: Running the pump in this position will drain water from your pool. Observe water level to prevent
running the pump dry.
IMPORTANT: ALWAYS unplug power source to
pump before changing valve positions. Chang-
ing valve positions while the pump is running
could result in irreparable damage to the valve
and its inner workings.
CAUTION: NEVER USE THE VALVE LEVER AS A
HANDLE TO CARRY OR LIFT THE FILTER.
Changing Valve Positions
The 4 way valve is designed to provide the required
flow rate for each action described above. Always
make sure the power source
to the filter is unplugged before changing valve
positions. In other words, the pump should not be
running when you change valve
settings (i.e. moving from FILTRATION position to
the BACKWASH position). Changing valve positions
while the pump is running
could result in irreparable damage to the valve and
its inner workings. To change valve positions, press
down firmly on the valve
lever and rotate to the desired setting.
