Valve Position Function
FILTER
This is the standard normal operation position of your ltration system. The water ows in from your pool
and is distributed across the top of the sand bed in the lter. Through pressure, this water then ows down
through the sand allowing debris to be removed from the water and collected in the sand bed. Water is then
routed up through the laterals and the center stem pipe and is returned to the pool, usually via some form
of sanitation and/or heating. The FILTER position can also be used for manual vacuuming and cleaning.
BACKWASH
This position is used when your sand lter’s sand bed needs cleaning. Use the pressure gauge to monitor
when this is required, usually 8-10 PSI above the operation of a clean lter. When BACKWASH is selected,
the water ow is reversed and goes down the stem pipe and out through the laterals. This lifts the sand
bed and allows debris to be taken out of the lter and through the waste pipe. The sight glass will show the
quality of the water. Continue BACKWASH until the water visually clears.
RINSE
This setting is used after completing the BACKWASH cycle. In the RINSE setting, water is taken
from the pool and distributed on the sand bed. This downward ow settles the sand bed, disturbed
from backwashing, and carries any remaining loose dirt through the waste line. By using RINSE after
backwashing, you will eliminate any debris from returning to the pool water. Rinse until you see clear water
through the transparent sight glass. Time needed is about half the time of a BACKWASH cycle.
WASTE
The WASTE position allows you to pump excess water from the pool directly down through the waste pipe.
This position is useful after heavy rains when the water level is too high. Water is directed straight through
the multiport control valve and bypasses the lter, going directly to waste. You can also use this position to
vacuum heavy concentration of debris from the pool.
RECIRCULATE
Similar to the WASTE setting, RECIRCULATE allows the water to bypass the lter but go straight back
to the pool. This is a useful setting if you have applied some chemicals that need to be circulated, but not
removed by the lter. In addition, if a leak develops in the lter, use recirculate to continue circulating water
until leaks are located for xing.
CLOSED
The CLOSED setting acts like a valve and prevents the ow of water through the tank, and is particularly
useful when doing any maintenance on the ltration system.
