BACKWASHING
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 10 PSI or 70 kPa is indicated from your clean filter.
TO PERFORM THE BACKWASH OPERATION, YOU MUST FOLLOWING THESE STEPS:
1. Turn off filter pump
2. Change the position of the Multiport Control Valve handle from FILTER to BACKWASH
3. Turn filter 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 media, 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 until the water becomes clear.
5. Turn off filter pump
6. Change the position of the Multiport Control Valve handle from BACKWASH to RINSE
7. Turn filter pump back on. The water flow will now be directed back through the Media bed and
then out through the waste line. This will settle the media bed back for normal operation
8. Check sight glass. Continue until water is running clear
9. Turn off filter pump
10. Change the position of the Multiport Control Valve handle from RINSE to FILTER.
11. Turn on filter pump
