Chapter 4: Initial Startup of Filter

Chapter 5: Multiport Valve Operation

Filter: Position for filtering the body of water. 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 sand, dirt and debris are trapped by the filter bed, and filtered out. The filtered water is returned from the bottom of the filter tank, through the Multiport Valve and back through the piping system.

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 tank and up through the filter bed, flushing the previously trapped dirt and debris out the waste line.

Rinse: Position for flushing the filter system. The water flow is directed by the Multiport Valve through the filter bed and out the waste line. This process settles the filter media bed into place and ensures any dirt or debris is rinsed out of the filter, preventing possible return to the Swimming Pool or Spa.

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 to lower the water level or for vacuuming water with high dirt loads.

Re-circulate: Position for bypassing the filter bed to the Swimming Pool or Spa. The Mulitport Valve recirculates water flow directly back to the Pool or Spa, bypassing the filter.

Closed: Position for closing all flow to the filter. This position is not to be used with the pump operating. CAUTION: Operation of the Multiport Valve or mode selection is to be always done with the pump switched off.
