Valve Positions
BACKWASH – water flows through the sand in the opposite direction, washing away
impurities; instead of flowing back to the pool, it is drained through the "WASTE" port
– remove the cap!
BYPASS – water flows though the appliance, bypassing the sand filling.
WASTE – water bypasses the sand filling and flows into the "WASTE" port – remove the
cap! This position is used to reduce water level in the pool or extraction of rough
impurities.
VENTING/WINTERIZING – in this position, the valve is permeable in all directions; the
escaping air causes watering of the pump chamber. The position is also used for
winterizing or long-term filtering equipment shutdowns.
RINSE – this position is used when running for the first time with a new sand filling or
after BACKWASHING; the stirred sand sets down and remaining impurities are flushed
through the "WASTE" port – remove the cap!
FILTERING – primary position of the valve, the water is filtered through the sand filling
and returned to the pool.
CLOSED – do not turn the appliance on!
