INSTALLATION OF MULTIPORT VALVE
Side Mount Fibreglass Filters are supplied with the option of a Side Mount Multiport Valve with a
plumbing kit designed to be connected to the side ports of the filter.
1.
Align the Multiport Valve’s plumbing kit with the filter’s threaded connection ports. Screw the
plumbing kit’s barrel unions onto the filter connection ports and hand tighten. Do not over
tighten the barrel unions as this can lead to damage and void warranty.
2. Screw the Multiport Valve barrel unions onto the threaded connection ports of Multiport Valve
and hand tighten. The barrel union should be firmly threaded into the Multiport Valve and there
should be no play between the thread. Do not over tighten the barrel unions as this can lead to
damage and void warranty.
3. Glue the PVC pipe to the barrel unions and Allow 24 hours for glue (solvent) to set before
starting the filter.
4. Test the filter and check for leaks around the threads.
MULTIPORT VALVE OPERATION
1.
Filter - Position for filtration
Incoming water from the piping system is automatically directed by the Multiport Valve to the
top of the filter bed. As the water is pumped through the filter bed, dirt and debris are trapped
by the filter bed. The filtered water is returned from the bottom of the filter vessel, through the
Multiport Valve and back through the piping system
2. Backwash - Position for cleaning the filter media
Water flow is reversed by the Multiport Valve through the filter bed so that water flow is
directed to the bottom of the filter vessel and up through the filter bed, flushing the previously
trapped dirt and debris out the waste line
3. Rinse - Position for flushing the filter system
The water flow is directed by the Multiport Valve through the filter bed and out. This process
settles the filter media bed into place and ensures any dirt or debris is rinsed out of the filter,
preventing dirt or debris returning to the system
NOTE: This position is not available on 4-Way Multiport Valves
4. Waste - Position for bypassing the filter bed to waste
The water flow is directed by the Multiport Valve straight to the backwash outlet, bypassing
the entire filter bed. This Multiport Valve position is used lower the water level or for vacuuming
water with high dirt loads
5. Re-circulate - Position for bypassing the filter bed
The Mulitport valve recirculates water flow directly back to the system, bypassing the filter
6. Closed – Position for closing all flow to the filter
The Multiport Valve can be closed to enable servicing of pump without draining the water from
the filter. This position is not to be used with the pump operating
NOTE: Operation of the Multiport Valve or mode selection is to be always done with the pump
switched off
