FILTER CONTROL VALVE FUNCTIONS
Filter-
FILTER – Set valve to FILTER for normal filtering. Also use for regular vacuuming.
Backwash-
BACKWASH – For cleaning filter sand. When filter pressure gauge rises 4-6 PSI above start-up (clean
pressure): Stop the pump, set valve to BACKWASH. Start pump and backwash until water in sight
glass is clear. Approximately 2 minutes or less depending on dirt accumulation. Proceed to RINSE.
Rinse-
RINSE – After backwashing, and with pump
OFF
, set valve to RINSE. Start pump and operate for
about ½ to 1 minute. This ensures that all dirty water from backwashing is rinsed out of the filter to
waste, preventing possible return to the pool. Stop pump, set valve to FILTER and start pump for
normal filtering.
Waste-
WASTE – To bypass the sand filter for draining or lowering water level and for vacuuming heavy
debris or very fine dusty particles directly to waste.
Re-circulate-
RE-CIRCULATE: Water is re-circulated through the pool system, bypassing the sand filter.
Closed-
CLOSED – Shuts off flow from pump to filter.
