MULTIPORT (4 & 6 Way) 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 lter bed. As the water is pumped through the lter bed, dirt and debris are trapped by the lter
bed. The ltered water is returned from the bottom of the lter vessel, through the Multiport Valve and
back through the piping system.
2. Backwash - Position for cleaning the filter media.
Water ow is reversed by the Multiport Valve through the lter bed so that water ow is directed to
the bottom of the lter vessel and up through the lter bed, ushing the previously trapped dirt and
debris out the waste line.
3. Rinse - Position for flushing the filter system.
The water ow is directed by the Multiport Valve through the lter bed and out. This process settles
the lter media bed into place and ensures any dirt or debris is rinsed out of the lter, preventing dirt
or debris returning to the Swimming Pool / Spa.
NOTE: This position is not available on 4-Way Multiport Valves.
4. Waste - Position for bypassing the filter bed to waste.
The water ow is directed by the Multiport Valve straight to the backwash outlet, bypassing the entire
lter 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 to the Swimming Pool / Spa.
The Mulitport valve recirculates water ow directly back to the Swimming Pool / Spa,
bypassing the lter.
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
lter. This position is not to be used with the pump operating.
NOTE: This position is not available on 4-Way Multiport Valves.
!
Operation of the Multiport Valve or mode selection is to be always done with the pump switched off.
