3.1 I Operati ng principle
The fi lter is essenti al for a swimming pool since it contributes to water treatment and ensures its clarity.
Water passes through the fi lter cartridge in the fi lter vessel and impuriti es are removed.
The greater the accumulati on of impuriti es, the more the pressure in the fi lter will increase. When switching on the
system, mark the normal operati ng pressure with the "CLEAN-DIRTY" ring on the pressure gauge. when the pressure
r0.7 bar (10 psi) above normal operati ng pressure, the cartridge must be cleaned.
3.2 I Operati on
•
To prevent any risk of explosion that might cause damage to equipment, serious injury or
even death, make sure that the hydraulic circuit is free of any debris or blockage and is not
subject to excessive pressure and that the fi lter lid locking ring is properly installed.
•
Ensure that all valves are open and/or that the power of the fi lter pump is suitable for the size
of the fi lter if the initi al pressure is greater than 1.2 bar (17 psi).
•
The fi lter cover must be correctly ti ghtened and its seal clean and in place (on the clamping ring inside the cover). If
necessary, apply a silicone based lubricant to facilitate installati on.
•
Check that the hydraulic connectors, ground fi xing screws, etc. are correctly ti ghtened,
•
Ensure that the fi lter is properly stable; it should be level.
• The hydraulic circuit must be bled and not contain any foreign bodies.
•
Open the valves.
•
Open the air release on the fi lter cover.
•
Stand clear of the fi lter and start the pump.
•
When the water level in the fi lter is at maximum, water escapes through the air release, which should then be closed.
•
Check that there are no leaks on the hydraulic circuit.
•
Place the "CLEAN" arrow on the pressure gauge "CLEAN-DIRTY" ring on the value for the initi al pressure in the fi lter.
The pressure should not exceed 1.2 bar (17 psi).
The "CLEAN" arrow positi on indicates the fi lter's initi al operati ng pressure and that the fi lter cartridge is clean.
Tip: installati on with a variable speed pump
•
For an installati on with a variable speed pump, it is normal to have low initi al pressure if the fi ltering
speed is low, and vice versa. In such a case, always use the same fi ltering speed as a comparison reference
for the "CLEAN-DIRTY" indicati on.
