SECTION III.

START-UP PROCEDURE

1. Be sure the correct amount of silica filter sand is in the tank, see Table 1, 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.
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.
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.
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.
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.
To prevent damage to the pump and filter and for proper operation of the system, clean pump strainer and skimmer baskets
regularly.
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.
SECTION IV.

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 V.

FILTER BACKWASH PROCEDURES.

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.
