Pentair filter - Manual (Page 4)

P/N 99223000 4 Rev. D 5-11-01
11. Connect black hoses to the equipment and the pool with the clamps provided.
a. Connect skimmer suction port from pool to pump inlet.
b. Connect filter valve return port to return fitting of pool,
see Figure 4.
12. Never install a pump in this system that exceeds the maximum pressure of this filter (see data label).
Section IV. Initial Start Up.
1. Be sure the correct amount of Silica filter sand is in the tank and that all connections have been made and are secure.
2. Check that the backwash is open so that water is free to flow from the pool and out the backwash line. Set the control valve to Backwash
position.
3. Stand clear of the filter. Prime and start pump according to the pump instructions allowing the filter tank to fill with
water. Once the water flow is steady out of the waste line, run the pump for at least two minutes. This initial backwashing
of the filter is recommended to remove any impurities of fine sand particles in the Silica sand media.
10. Assemble all piping to the pump and valve. The pump to
filter hose must be connected to the port marked pump on the
control valve first, then it can be connected to the pump.
Make sure the O-ring is in place on the pump swivel union
connection before attaching the hose to the pump.
CAUTION
Figure 1. Use Teflon Tape
Use O-ring
Figure 2. Backwash Fitting
Figure 3. Use O-ring
Figure 4.
Use only teflon tape (3 layers) on all threaded male connections,
see Figure 1. Do not use Teflon tape on fittings with an O-ring seal,
see Figures 2 and 3. Use of petroleum based pipe joint compounds
can damage components of this system causing leaks.
This filter operates under pressure. With the valve clamped properly and operated without air in the system, this filter
will operate in a safe manner. Air entering the filter and the valve not clamped correctly can cause the valve to be
blown off, which could cause severe personal injury and/or property damage.
WARNING
4. Turn the pump off and set valve to rinse position. Ensure that all pool suction and return lines are open so that water is free
to flow from the pool to waste. Stand clear of filter and start the pump.
5. Run the pump for at least two minutes.
6. Turn the pump off and set valve to filter position. Ensure that all pool suction and return lines are open so that water is free
to flow from and to the pool. Stand clear of filter and start the pump.
7. Your filter has now started its filtering cycle. You should check that water is returning to the pool and take note of the
operating pressure. My original starting pressure is ____________ PSI with the filter clean.
8. Check the system for water leaks. If a leak is found, shut pump off before correcting the leak.
9. As the filter removes dirt and impurities from the pool water, the accumulation will cause the filter pressure to rise and
flow to diminish. When the pressure gauge reading is 5 to 7 PSI higher than the clean filter reading noted above, it is time
to backwash the filter.
Always turn pump off before changing valve positions. Changing valve positions while the pump is running can damage the
control valve, which may cause personal injury or property damage.
