6. Carefully note the pressure reading at that time and the position of the needle on the pressure gauge. As the filter

operates, impurities are retained and the pressure increases in the tank.

When it exceeds the initial pressure (clean filter) by 10 PSI (0.7 bars or kg/cm 2 ), the filter must be backwashed.

Note 1: When your pool water is cleaned for the first time, it may be necessary to backwash the filter frequently: it is likely

to contain a significant quantity of impurities.

Note 2: Clean the strainers of the pump and skimmers regularly to ensure trouble-free operation of your filtration system.

Note 3: Installations including heaters or cleaning systems with nozzles or tentacles protruding from the walls are highly

sensitive to pressure surges because they operate at high pressure. The installer must do everything necessary to prevent

pressure surges in the installation.

FILTER

Set the valve to ''Filter'' for normal filtration (10 to 14 hours a day).

BACKWASH

For cleaning the filter when the filter pressure gauge rises 10 PSI (0.7 bars or kg/cm 2 ) above start-up (clean) pressure.

Stop the pump, set the valve to "Backwash". Run the pump until the water in the sight glass is clear. Stop the pump about

2 minutes later and set the valve to ''Rinse''.

RINSE

With the valve set to ''Rinse'', run the pump for about one minute. This evacuates the dirty backwash water to a drain, not

the pool. Stop the pump, set back to ''Filter'', and restart.

WASTE

The water is discharged directly into the sewer without passing through the filter: to lower the pool water level and directly

eliminate very dirty water when using the vacuum.

RECIRCULATE

The water bypasses the filter, for rapid dispersion of chemicals or for massive chlorination.

CLOSED

Cuts off circulation between the filter and the pump.

NEVER USE THIS POSITION WITH THE PUMP RUNNING.

1. Completely drain tank by unscrewing drain cap at base of filter tank. Leave cap off during winter.

2. Rotate and leave the valve handle set between any positions.

3. Drain and winterize pump according to pump instructions.
