OPERATIONS
Make yourself familiar with your filter system’s valve settings and functions.
Filter Valve Settings & Functions
Setting
Complete Water Flow/Function
Filtration
Vacuum, 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 30 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 reading s(5 - 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. This position is ideal for vacuuming pools with large amounts of debris or after an algae treatment. 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.
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.
IMPORTANT: ALWAYS unplug power source to pump before changing valve positions. Changing 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.
