Filter Backwash Procedure
WARNING —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 flow out
the backwash line. Set control valve to backwash position.
3. Stand clear of the filter and start the pump.
4. Backwash filter for approximately 3 to 5 minutes or until backwash water is clean.
5. Stop the pump and set valve to rinse position.
6. Stand clear of the filter and start the pump.
7. Rinse filter for approximately 30 seconds.
8. Stop the pump and set valve to filter position.
9. Ensure that pool return line is open so that water may flow freely from the pool back to the pool.
10. Open manual air bleeder on 6-Way Valve, (except TA 100D) . Stand clear of filter and start the pump.
11. Close manual air bleeder on the 6-Way Valve, (except TA 100D), when all the air is removed and a steady stream
of water emerges from the bleeder.
12. The filter has now started its filtering cycle. You should ensure that water is returning to the pool and take note
of the filter pressure.
13. The filter pressure, in the above Step 12, should not exceed the pressure originally observed on the filter 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.

Chemical Cleaning Procedure

1. It is recommended that one of the following cleaners be used:
a. FILTER-CLEANSE – Great Lakes Biochemical
b. FITLER-FREE – Hydrotech Chemical Corp.
c. KLEEN-IT – Bio Lab, Inc.
These cleaners will remove oils, scale and rust from the sand bed in one cleaning operation.
2. Mix a solution following the manufacturers instructions on the label.
3. Backwash the filter with the Multiport Valve as outlined above.
4. If the filter is below pool level, shut off the pump and close appropriate valving to prevent draining the pool.
5. Shut off pump, open filter drain and let filter drain. Place valve in backwash position.
6. After filter has drained, close filter drain and remove the pump strainer pot lid.
7. Ensure that the backwash lines are open.
8. Turn the pump on and slowly, pour the cleaning solution into the pump strainer with the pump running. If the
filter is below pool, open shut-off valve slightly to allow pump to run.
9. Continue adding solution until the sand bed is saturated with cleaning solution.
10. Shut off the pump and leave filter in backwash position. Allow filter to stand overnight (12 hours).
11. Replace the pump lid and follow backwash procedures as outlined above.
12. Do not allow the cleaning solution to get into the pool.
