8.   Ensure the closure o-ring is clean and in the correct position. If necessary, apply 

a thin film of oring lubricant to the o-rings. Assemble the multiport valve to the 

tank aligning the ports to the appropriate plumbing.

9.   Connect barrel unions utilising O-Rings supplied on fittings and screw into the 

multiport valve body.

10. Connect the pressure gauge to the air bleed port utilising the supplied O-ring on 

the air bleed plug. Do not apply Telfon tape to the pressure gauge thread as it 

may damage the valve.

CAUTION

•   A non return valve is required between pump and pool on the inlet side.

•   On installations where the waste line is more than 3 metres below pool 

water level and more than 12 metres in length, a vacuum break valve 

must be fitted in the waste line close to the filter.

•   If an auxiliary pump is installed in line downstream of the filter, it should 

be protected against causing negative pressure in the filter tank.  A flow 

or pressure switch which only enables the auxiliary pump to run when 

the main filter pump is running will achieve this.

•   If the pump and filter are located below pool water level, it is necessary 

to fit isolating valves in the pipe between the pump and the skimmer 

box and in the return pipe from the multiport valve to the pool.  This 

prevents water draining from the pool during maintenance.

FAILURE TO COMPLY WITH THE ABOVE CAUTIONS MAY RESULT IN FILTER 

DAMAGE NOT COVERED BY THE GUARANTEE.

Pipe Connections

Use Teflon tape on all male threads.  Piping should be independently supported and 

not impose heavy loads on the filter or pump.  Use 40mm or 50mm (1

” or 2”) pipe 

from the pump to the skimmer box, return pipe for the multiport valve to the pool and 

from the multiport valve to the drain.

DO NOT OVERTIGHTEN

The fittings and multiport valve on this product are constructed of 

ABS.  Some PVC jointing compounds are incompatible with ABS.  

Check compound suitability before use.

For models that use the 40mm (1.5”) valves, i.e. DEP2140, DEP2540

If the pipe length in the installation, is less than 15m, use the supplied 40mm barrel 

unions as provided with 40mm PVC pipe.
If the pipe length in the installation is greater than 15m, 50mm PVC pipe is 

recommended and the supplied unions should be adapted to suit. 50-40 reducing 

adapters will need to be purchased at your local building/plumbing supplier.

For models that use the 50mm (2”) valves, i.e. DEP2850, DEP3250, DEP3650, DEP4050

 

It is recommended to use 50mm PVC pipe, regardless of the length of the pipe.  

50mm barrel unions are provided with the multiport valve for connection of PVC pipe 

to “pump”, “pool return” and “waste”

NOTE:

Ensure pipework is connected to appropriately labelled multiport 

valve connections.
