FILTER CARTRIDGE MAINTENANCE
To ensure maximum life from your MultiCyclone Plus/Ultra’s filter cartridge you need to maintain
the filter cartridge 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 operating 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 once the pressure gauge has reached 50kPa (7.2psi)
above the operating pressure.
Example: Filter operates normally at 60kPa (8.2psi) needs to be cleaned at
110kPa (16psi).
Cartridge Cleaning
Prior to removing the MultiCyclone Plus/Ultra cartridge filter’s lid, you will need to release the
pressure from the filter cartridge housing. With the pump off, loosen the air release valve on top
of the MultiCyclone Plus/Ultra filter lid to release pressure from the filter housing.
1. Undo and remove the clamp around the cartridge filter’s lid by unscrewing the tightening
nuts, this can be either by hand or using a 25mm (1”) open end spanner/adjustable wrench
on the moulded hexagon section and remove the lid off the filter tank.
2. Remove the filter cartridge from the filter housing.
3. Using a garden type hose clean the surface of the pleated element. Make sure to clean
between the pleats.
4. Place the filter cartridge back into the filter housing ensuring that it is seated correctly.
5. Ensure the lid “o”-ring is clean of any debris and is correctly seated into filter body “o”-ring
groove prior to lid being refitted.
6. Place the lid onto the filter housing and refit retaining clamp band and tightening nuts using
a 25mm (1”) open end spanner/adjustable wrench ensuring lid is correctly fitted.
7. Refer to the start up procedure to recommence operation.
