Filter Backwash Procedure
To prevent equipment damage and possible injury, always turn off pump before changing valve positions.
1. Stop the pump.
2. Ensure that the suction and backwash lines are open so that water is free to come from the pool and ow out
the backwash line. Set control valve position as follows:
a. If using a Multiport Valve, set valve to backwash position.
b. If using a Two Position Slide Valve, push handle down to backwash position and engage lock by twisting
handle.
3. Stand clear of the lter and start pump.
4. Backwash lter for approximately 3 to 5 minutes or until backwash water is clean.
5. Stop the pump.
a. If using a Multiport Valve, set valve to rinse position and continue with remaining steps.
b. If using a Two Position Slide Valve, skip to step 8.
6. Stand clear of the lter and start pump.
7. Rinse lter for approximately 30 seconds.
8. Stop the pump and set valve as follows:
a. If using a Multiport Valve, set valve to lter position.
b. If using a Two Position Slide Valve, raise handle to lter position and engage valve lock by twisting
handle.
9. Ensure that pool return line is open so that water may freely ow from the pool back to the pool.
10. Open manual air bleeder on Triton closure. Stand clear of lter and start pump.
11. Close manual air bleeder of the closure when all the air is removed and a steady stream of water emerges
from the bleeder.
12. The lter has now started its ltering cycle. You should ensure that water is returning to the pool and take
note of the lter pressure.
13. The lter pressure, in the above Step 12, should not exceed the pressure originally observed on the lter
when it was initially started. If after backwashing, the pressure is 4 to 6 PSI above the start condition, it will
be necessary to chemically clean the sand bed.
