VALVE OPERATIONS

Make yourself familiar with your filter system's valve settings and functions.
Filter Valve Settings & Functions
Setting
Complete Water Flow/Function
Filtration
Function: 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
Function: Use after backwashing to clean and resettle filter bed. This should always be done immediately after back-
washing, 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.
Circulation
Function: Circulate water after chemical treatment. This position is used during certain pool cleanups and chemical
treatments when you don't want the water contaminating the sand. In this position, water is only directed through
the valve back to the pool and does not filter through the sand.
Backwash
Function: 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 to 10 psi above its normal reading 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.
Closed
Function: Cleaning the hair and lint strainer. This position stops the flow of water into the pump and filter.
CAUTION: Do not run pump with valve in this position.
Purge/
Function: Bypass the filter. This position is ideal for vacuuming pools with large amounts of debris or after an algae
Drain
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 6 position multi-port 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.
Changing valve positions while the pump is running could result in irreparable damage to the valve and its inner workings.
SAVE THESE INSTRUCTIONS
IMPORTANT
ALWAYS unplug power source to pump before changing valve positions.
NEVER use the valve lever as a handle to carry or lift the filter.
