Pentair filter - Manual (Page 5)

1. Turn off pump.
2. Ensure that suction and backwash lines are open so that water is free to come from the pool and flow out the backwash
line. Set the control valve to backwash position.
3. Stand clear of the filter and start pump.
4. Backwash filter for approximately 3-5 minutes or until backwash water is clean.
5. Turn off pump. Set control valve back to rinse position.
6. Stand clear of the filter and start pump.
7. Rinse filter for approximately 3-5 minutes.
8. Turn off pump. Set control valve back to filter position.
9. Stand clear of the filter and start pump.
10. The filter has now started its filtering cycle. Check that water is returning to the pool and take note of the filter pressure.
11. The filter pressure in step 10 above should not exceed the pressure originally observed on the filter when it was initially
started. If after backwashing the pressure is 4-6 PSI above the start condition, it may be necessary to change the sand in the
filter.
To prevent damage to the pump and filter and for proper operation of the system, clean pump strainer and skimmer baskets
regularly.
CAUTION
Section V. Cleaning Frequency.
1. Cleaning frequency will vary from pool to pool and with other factors such as weather condition, heavy rains, dust, pollen,
bather load, and water chemistry. Check the pressure gauge reading on a regular basis and when the pressure gauge reading
increases 5 to 7 PSI over the initial clean filter reading, it is time to backwash your filter.
2. It is important NOT to backwash the filter solely on a timed basis such as every two days. It is also important to note that
backwashing too frequently actually causes poor filtration.
Section VI. Filter and Control Valve Functions.
FILTER - From pump, through valve, downward through filter sand bed, up through center pipe to valve return port, and
back to the pool for normal filter action and vacuuming pool through filter.
BACKWASH - From pump, through valve down through center pipe, up through filter sand to valve, and out waste port. This
position is used for cleaning filter by reversing flow.
RINSE - From pump through valve downward through filter sand, up through center pipe to valve and out waste port. This
position is used for start up cleaning and resettling filter bed after backwashing.
WASTE - From pump, through valve (bypasses filter) and goes to waste port. This position is for vacuuming directly to
waste, lowering pool level, or draining pool.
CLOSED - NO FLOW IN THIS POSITION - DO NOT USE THIS SETTING WITH PUMP OPERATING.
RECIRCULATE - From pump, through valve, bypasses filter and goes to return port and back to pool. This position is for circulating
water without going through filter.
WINTERIZING - Valve position for a winterized filter, see page 10.
Section VII. Filter Backwash Procedures.
Failure to operate your filter system or inadequate filtration can cause poor water clarity obstructing visibility in your pool. Poor
water clarity may obscure objects in the water which while swimming and diving could cause severe personal injury or death.
Never swim in a pool with poor water clarity.
