BACKWASHING THE FILTER
can be done by turning the multi-position valve to
the backwash position. This reverses the flow of water through the filter, raises the
sand bed, and cleans it. The reversed flow carries the dirt and debris out through the
waste line.
Always turn the pump off before turning the multi-position valve
.
•
With the valve in the
backwash
position, open the valve on the waste line
and turn on the pump. Allow it to run for 2 to 4 minutes until the waste-
water is clear. (You can watch the water through a sight glass in the filter
housing.)
•
Shut off the pump and turn the valve to the
rinse
position, allowing the
water to flow through the filter bed in the normal direction and into the
waste line.
•
Turn the pump back on and run for about 15 to 20 seconds. This resets the
sand bed and prevents any dirt from reentering the pool when you start
filtering again.
•
Shut the pump off and turn the valve to
filter
position, the normal
position for routing the water through the filter and back to the pool. Turn
the pump back on. Close the valve on the waste line.
•
The valve has other positions as well: The
recirculate
position by-passes
the filter and can be used until the filter is serviced. The
waste
position
discharges water from the pool directly into the waste line. Use this
position to lower the water level or to get rid of a lot of dirt when
vacuuming. (Remember to open the valve on the waste line). The
closed
position is used when the system is not running.
Never run the pump
with the valve in the closed position.

Hose the coping and deck
. Keep the spray directed away from the pool to prevent
silt from being washed into the clean water.
