5. Run the pump for at least two minutes.
6. Turn the pump off and set valve to filter posi-
tion. 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 pres-
sure to rise and flow to diminish. When the pressure
gauge reading is 10 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 chem-
istry. Check the pressure gauge reading on a regular
basis and when the pressure gauge reading increases
10 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 frequent-
ly actually causes poor filtration.
Section V. Filter and Control Valve Functions.
FILTER -
From pump, through valve, down-
ward through filter sand bed, up
through center pipe to valve return
port, and back to the pool for nor-
mal filter action and vacuuming
pool through filter.
BACKWASH -
From pump, through valve down
through center pipe, up through fil-
ter sand to valve, and out waste
port. This position is used for
cleaning filter by reversing flow.
RINSE -
From pump through valve down-
ward 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 back-
washing.
WASTE -
From pump,
through valve
(bypasses filter) and goes to waste
port. This position is for vacuum-
ing 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 posi-
tion is for circulating water with-
out going through filter.
WINTERIZING - Valve position for a winterized fil-
ter, see page 10.
Section VI. 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.
CAUTION
To prevent damage to the pump and filter and for proper
operation of the system, clean pump strainer and skimmer
baskets regularly.

WARNING
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 per-
sonal injury or death. Never swim in a pool with poor water
clarity.

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.
Section VII. Winterizing the Filter.
1. In areas that have freezing winter tempera-
tures, the pool equipment must be winterized to pro-
tect it from damage.
2. Backwash the filter. Shut off the pump and set
the control valve to the winterize position.
3. Remove the drain port cap at the bottom of the
filter.
IMPORTANT NOTE
Remove drain port cap only for draining water from filter. Removing
the entire fitting will allow sand to drain also. The filter will drain slow-
ly. Leave the drain port cap off and store it during the time the system
is shut down.
4. Drain all appropriate system piping.
5. It is recommended that the pump and filter be
covered with a tarpaulin or plastic sheet to inhibit
deterioration from the weather. DO NOT wrap pump
motor with plastic.
CAUTION
The control valve should be left in the winterize position dur-
ing the shutdown season so that the rubber seal of the valve
diverter has no pressure on it. Failure to do so can damage
the valve diverter seal which can cause property damage
from leaking water.
