7. Remove the sand guide and all traces of media from the tank flange.
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. Apply Teflon tape to the thread on the pressure gauge and barrel unions and
screw into the multiport valve body. 7 turns of tape is required.
CAUTION
• A non return valve is required in between the pump and filter.
• 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
1
/
2
” 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.
