Note 3 : Installations including heaters or cleaning systems with nozzles or tenta-
cles protruding from the walls are highly sensitive to hydraulic rams because they
operate at high pressure. The installer must do everything necessary to prevent
hydraulic rams in the installation.
FUNCTIONS OF VALVE AND FILTER
Your system may have a four- or six-way valve (fig. 3).
FILTER
Set the valve to "Filter" for normal filtration (6 to 8 hours a day).
BACKWASH
For cleaning filter. When filter pressure gauge rises 10 PSI (0.7 bars or kg/cm2)
above start-up (clean pressure)
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", when this position exists.
RINSE (6-way valve only)
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 to the sewer without going 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 (6-way valve only)
Cuts off circulation between the filter and the pump.
NEVER USE THIS POSITION WITH THE PUMP RUNNING.
WINTERIZING
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 between any position or on "WINTER" posi-
tion if existing.
3. Drain and winterize pump according to pump instructions.
