Your sand filter is equipped with a 4 position or 6 position multiport valve. The 4 position valve
has Filter, Backwash, Recirculate and Waste positions. The 6 position includes these
positions and also offers a Rinse and Closed setting- see details on each setting, below. Each
multiport valve is equipped with an external air bleeder device.
Always
open this air bleeder
and stand clear of filter and valve before starting the system pump and leave open until a
steady stream of water is expelled.
CAUTION
: To prevent equipment damage and possible
injury, always turn pump off before changing valve position.
The valve has a closed
position. The pump should never be on when the valve is in the closed position. If the pump is
operated with the valve closed, the air relief system becomes inoperative and an explosive
situation could exist. Additionally, running the system with no flow will seriously damage the
equipment.

1.
FILTER POSITION
- This is the process by which the
water from the pool passes through the filter tank and
the sand. As the water trickles down through the sand,
the dirt and debris are trapped by the sand, thus
filtering the water. The filter should be operated a
minimum of 8 hours a day.
2. BACKWASH POSITION
- This process is used to
clean the debris that has accumulated, out of the
sand. The water is essentially moving in a reverse
fashion. This should not be done for more than one
minute at a time, and should be done when the flow of
water back to the pool has slowed considerably and
the pressure gauge has doubled the original normal
starting pressure.
3. RINSE POSITION
- This is done after backwashing to
settle the sand and cloudy water inside the tank
caused by backwashing, so sediment will not pass
back into the pool.
4.
RECIRCULATE POSITION
- Water is passed from the skimmer to the pump and then up to
the valve; however, instead of passing through the sand, it passes through the valve head
and then back into the pool. Re-circulate is used to circulate chemicals without filtering; this
will simply circulate the water throughout the pool.
5.
WASTE POSITION
- this function is used when one desires to draw water or vacuum debris
from the pool directly onto the ground (bypassing the tank). For example, if there is a lot of
debris accumulated on the floor of the pool, one would use this process to vacuum it from
the pool onto the ground; bypassing the filter tank.
6.
CLOSED POSITION
- this position is used when one wishes to shut off water flow through
the valve. The valve is left in this position for winter closeup, since it shuts off all of the
passageways through the valve.
REMEMBER NEVER CHANGE VALVE POSITIONS WHEN PUMP & MOTOR IS RUNNING
