START UP PROCEDURE
The Opal Cartridge Filter is a simple and effective unit which will provide years of trouble free service if the
following maintenance procedures are maintained.
To start up the filtration system either from new or after cleaning is exactly the same.
1. Ensure that all valves installed before or after the filter are open.
2. Ensure that the filter is plumbed correctly. Pipe from pump outlet must be attached to the filter inlet port.
3. Loosen the air bleed screw on top of the filter lid.
4. Prime the swimming pool pump.
(Refer to the pump installation and operation manual).
5. Turn on the swimming pool pump and allow the pump to run until all the air has been expelled from the filter
vessel. Water will run from the air bleed screw.
6. Tighten the air bleed screw.
7. The filter is primed and ready for operation.
In some cases this may be required to be done a few times before the unit will remain primed and be
fully operational.
Do not stand over the lid whilst adjusting the air bleed to purge the system of air.
Injury may occur if air bleed valve comes loose.

CAUTION
MAINTENANCE
To ensure that you get maximum life from your Opal Cartridge Filter you will need to maintain the filter regularly.
When the filter is first started and has been purged of air, note the pressure on the pressure gauge. This is what is
known as the filter operation pressure and it is important that you be aware of this figure.
All filtration systems will operate at different pressures depending on the pool hydraulics.
You will need to clean the filter cartridge (element) once the pressure gauge has reached 50 kPa above the
operating pressure.
The Opal Cartridge Filter has a maximum operating pressure of 250 kPa.
EXAMPLE: Filter operates normally at 60 kPa needs to be cleaned at 110 kPa.
