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.
