1. Install Cartridge filter on a clean, stable and level base
on which the circulation pump is located.
2. The CL Cartridge Filter has two 50mm water
connections. The 2 inlet ports (from pump) are
located at the bottom of the filter. The 2 outlet port are
located on the opposite side of the filter. The inlets and
outlets are marked on the tank. The un-used inlet and
outlet ports should be capped using the caps provided.
For installations where the flow rate is above 350 litres
per minute, both Inlet and outet ports may be used.
The PVC pipe can be manifolded together to achieve a
maximum flow rate of 700 litres per minute.
3. Allow a minimum on one hour for glue to dry.
4. Using Teflon tape, screw pressure gauge into lid.
5. If filter is installed below water level, isolation valves must be installed on the inlet and outlet to enable
the filter to be dismantled for cleaning without the loss of water from the pool or spa.
6. It is also recommended that a three way valve be installed on the return line to allow draining of water
from the pool or spa when necessary.
1. Before start up make sure the cartridge is in the filter and the lid lock ring is tightened until the safety
catch locks – do not over tighten.
2. Open the suction and return line valves (where fitted).
3. Loosen the air release valve on the filter lid, start pump until water escapes the air release valve.
Tighten air release valve and check there is a good flow of water back in the pool.
4. Clean the cartridges when the flow to the pool reduces or the pressure gauge increases by 20 kPa.
1. With the pump OFF, remove the lid from the pump strainer and pour in approximately 4 litres of water.
2. Replace lid.
3. If valve has been installed on the pump suction line, close before filling strainer. Open again after lid has
been securely fastened in place. Any valves on the return lines should be open. The pump should not
need to be re-primed unless the pump has been drained for servicing, or winterizing (refer to complete
pump operations manual provided with pump).
