6) CLOSED
Closed setting acts like a Valve and prevents flow of water through the Tank, particularly useful
if doing any maintenance on the filtration system.
BACKWASHING YOUR FILTER
Cleaning your Filter will give you the best quality swimming water that is clean, clear and safe
for swimming. It is highly recommended to clean on a regular basis and to monitor the pressure
gauge and BACKWASH when an increase of 5 PSI or 35 kPa is indicated from your clean filter.
TO PERFORM THE BACKWASH OPERATION, YOU MUST FOLLOWING THESE
STEPS:
1.
Turn off Pump
2.
Change the position of the Multiport Control Valve handle from FILTER to BACKWASH
3.
Turn Pump back on. The water flow is automatically reversed through the Filter so the
water is directed from the bottom of the tank, up through the sand, flushing the trapped
dirt and debris out of the waste line.
4.
Check Sight Glass. The duration of the backwash operation will depend on how dirty your
filter is. Continuously check the sight glass to see when the water becomes clear, then
5.
Turn off Pump
6.
Change the position of the Multiport Control Valve handle from BACKWASH to RINSE
7.
Turn Pump back on. The water flow will now be directed back through the Sand bed and
then out through the waste line. This will settle the sand bed back for normal operation.
8.
Check Sight Glass. Continue until water in Sight Glass is clear, usually about half the
time of the backwash cycle.
9.
Turn off Pump
10.
Change the position of the Multiport Control Valve handle from RINSE to FILTER.
11.
Turn on Pump
WARNING
Turn off the pump before switching the control
valve handle.
