FILTER OVERVIEW
Your high-rate sand filter is designed to produce clear,sparkling water and
operate for years with a minimum of maintenance when installed,operated
and maintained in accordance with these instructions.
Your filter uses special filter sand to remove dirt particles from pool water.
Filter sand is loaded into the filter tank and functions as the dirt-removing
media.The pool water,which contains suspended dirt particles,is pumped
through your piping system and is automatically directed by the filter
control valve to the top of the filter tank.As the pool water is pumped
through the filter sand,dirt particles are trapped by the sand bed and
filtered out.The cleaned pool water flows from the bottom of the filter
tank,up through the standpipe,and back to the valve on top of the filter
where the clean water is returned to the pool through the piping or hoses.
After a period of time,the accumulated dirt in the filter causes a resistance
to flow,and the flow diminishes.This means it is time to clean(backwash)
your filter.With the control valve in the backwash position,the water flow is
automatically reversed through the filter So that it is directed to the bottom
of the tank,up through the sand flushing the previously trapped dirt and
debris out of the waste line.Once the filter is back washed(cleaned)of
dirt,the control valve is manually resequenced to Rinse and then Filter to
resume normal filtering.

INSTALLING THE FILTER
Read and understand all instructions before attempting to
install,operate or maintain your pump and sand filter system.
1.Carefully remove all individual components from the carton and inspect
for any visible damage.If the carton or parts are damaged,contact the seller
or freight company.

- 9 -
2.The filter system should be installed not more than 50cm above pool
water level,on a level concrete slab,very firm ground,or equivalent,as
recommended by your pool dealer.When the filter is filled with sand and
water,it can weigh several hundred pounds.Position the filter so that the
piping connections,control valve and winter drain is
accessible for operation,service,and winterizing.
3.Assemble the drain to the lower outlet at the bottom of the filter
tank.Make sure that the o-rings are correctly assembled to prevent water
leakage.See the figure below.
Blockage of suction fittings can cause serious or fatal injury due to
drowning.To reduce the risk of injury,do not permit children to use
Never work on the pump while it is running or power is still
connected.High voltage can cause serious or fatal injury.A suitable
ground fault interrupter(GFCI)should always be installed at the power
supply source of this unit.Be sure to ground the motor before
connecting it to the electrical AC power supply.Failure to ground the
motor can cause a serious or fatal electrical shock hazard.DO NOT
ground to a gas supply pipeline.

- 10 -
4.Place the filter tank on the system base and rotate clockwise a little
bit.Position the filter tank,so the winter drain faces the opposite direction of
the pump.
5.Assemble the pump to the system base.
6.Place the standpipe and underdrain assembly in the center of the
tank.Cap the standpipe with a sand shield to prevent sand from entering
it.Fill the tank with about half-full water.(Be sure the winter drain cap is
securely in place).Carefully pour in the correct amount and grade of filter
sand(Be sure the standpipe remains centered in the opening).
You must use only No.20 standard silica sand having a uniformity
coefficient of 1.75 or less.No.20 silica sand has a particle size of.018-.022
inches(.45 to.55 mm).
Note:Sand is not included.
7.Remove the sand shield from the standpipe.Wash away all sand around
the opening at the top of the tank.Be sure the top of the filter is free of any
sand or debris and valve o-ring is in place on the valve body.Insert Filter
Control Valve into the tank neck,taking care that the standpipe slips into the
hole in the bottom of the valve.
8.Position the valve so that the port locations are in the desired final
position.Valve ports are marked with the location of where they should be
connected,i.e.,the pump port must go to pump discharge,the waste port
must go to the waste line,and the return port must go to the pool return.
9.Wipe the filter flange clean.Place the flange clamp around the tank and
valve flange and assemble the screws and nuts with the hex key.Tighten
clamp screws firmly and visually check the valve tank and clamp assembly
to ensure that the joint is correctly assembled.

- 11 -
10.Wrap some Teflon pipe manufactured for the plastic pipe on the 14"NPT male
end of the gauge.Carefully screw the pressure gauge into the 1/4"NPT tapped hole
in the valve body.Do not over-tighten.
11.Screw the hose adaptors into the control valve port marked PUMP and pump
discharge port.Wrap five turns of Teflon pipe on each hose adaptor.Connect the
hose adaptors with a 1.5”hose and use a hose clamp to fix them.
12.Make a return to the pool pipe connection to the control valve opening marked
RETURN and complete other necessary plumbing connections,waste lines,suction
lines to pump,etc.
13.To prevent water leakage,be sure the winter drain cap is securely in place and
all pipe connections are tight.
FILTER CONTROL VALVE FUNCTIONS
FILTER:From the pump,through the valve,downward through the filter
sand bed,up through the center pipe to the valve return port,and back to
the pool for normal filter action and vacuuming the pool through the filter.
BACKWASH:From the pump,through the valve,down through the center
pipe,up through filter sand to the valve,and out waste port.This position is
used for cleaning the filter by reversing flow.
RINSE:From the pump,through the valve,downward through filter sand,up
through the center pipe to the valve,and out waste port.This position is
High Pressure:
Improper tank valve assembly could cause the valve to separate and
cause serious injury and/or major property damage.
KEEP SAFETY LABELS IN GOOD CONDITION AND REPLACE IF
MISSING OR DAMAGED.

used for start-up cleaning and resettling the filter bed after backwashing.
WASTE:From the pump,through the valve,bypasses the filter and goes to
the waste port.This position is for vacuuming directly to waste,lowering the
pool level,or
draining the pool.
CLOSE:NO FLOWIN THIS POSITION-DO NOT USE THIS SETTING
WHILE THE PUMP IS OPERATING.
WINTER:Valve position for a winterized filter.
INITIAL START-UP
1.On a new pool,clean the pool before filling the pool with water.
Excessive dirt and large particles can cause damage to the pump and
filter.
2.Ensure that all pool suction and WASTE lines are open so that water is
free to flow from the pool to the WASTE line.Set the control valve to
the BACKWASH position.
3.Check the valve clamp for tightness.
4.Check the pump strainer pot to be sure it is full of water(Ensure the hose
is full of water if there is no strainer basket).Tighten the pump lid.
Prime and start the pump,allowing the filter tank to fill with water.
5.Once the water flow is steady out the WASTE line,run the pump for at
least 2 minutes or until the backwash water is clean.This initial
backwashing of the filter is recommended to remove any impurities of fine
sand particles in the silica sand media.
6.Turn the pump off and set the valve to the“RINSE”position.Ensure that all
pool suction and WASTE lines are open so that the water is free to flow
DO NOT DRY RUN THE SAND FILTER.

- 13 -
from the pool to the WASTE line.STAND CLEAR OF FILTER and start the
pump.
7.Run the pump for at least two minutes.
8.Turn the pump off and set the valve to the“FILTER”position.Be sure that
all pool suction and RETURN lines are open so that water is free to flow
from and back to the pool.STAND CLEAR OF FILTER and start the
pump.
9.The filter has now started its filtering cycle.You should ensure that
water is returning to the pool and take note of the operating pressure when
the filter is clean.
10.Check the system for water leaks.If a leak is found,shut the pump off
before correcting the leak.
11.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 5-10 psi higher than the
clean filter reading noted above,it is time to backwash the filter.
CLEANING
1.The filter on a new pool should be back-washed,and cleaned after
approximately 48 hours of operation to clean out plaster dust and/or
construction debris.
2.There are three different ways to identify when the filter needs
backwashing.
·The most accurate indicator on pool systems with a flow meter is to
backwash when the flow decreases 30%from the original(clean
filter)flow.For example,if the original flow was 60 GPM,the filter should be
back-washed when the flow is reduced by about 20 GPM(or 30%)to 40
GPM.

- 14 -
·A more subjective and less accurate indicator is to observe the amount
of water flowing from the flow directionals located in the wall of the
pool.The filter should be back-washed once it is detected that the flow
has been reduced.
·The most commonly used but less accurate indicator is to backwash
when the filter gauge reading increases by 10 PSI over the initial(clean
filter)reading.
3.It is important not to backwash the filter solely on a timed basis,such as
every three days.It is also important to note that backwashing too
frequently actually causes poor filtration.Factors like weather conditions,
heavy rains,dust or pollen,and water temperatures all affect the frequency
of backwash.As you use your pool,you will become aware of these
influences.
4.To prevent damage to the pump and filter and for proper operation of the
system,clean the pump strainer and skimmer baskets regularly.
5.If,at any time,the starting pressure after backwashing the filter indicates 4
to 6 PSI higher than the normal starting pressure,it is time to perform a
chemical cleaning procedure.
FILTER BACKWASH PROCEDURE
1.Stop the pump.
2.Ensure that the suction and WASTE lines are open so that water is free
to come from the pool and flow out the WASTE line.Set the control valve to
Always turn the pump off before changing valve positions.
Changing valve positions while the pump is running can damage the
control valve,which may cause serious injury or property damage.

the“BACKWASH”position.
3.STAND CLEAR OF 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 the valve to the“RINSE”position.
6.STAND CLEAR OF FILTER and start the pump.
7.Rinse the filter for approximately 30 seconds.
8.Stop the pump and set the valve to the“FILTER”position.
9.Ensure the pool RETURN line is open so that water may flow freely from
the filter back to the pool.
10.STAND CLEAR OF FILTER and start the pump.
11.The filter has now started its filtering cycle.Verify the water is returning
to the pool,and take note of the filter pressure when the filter is clean.
12.The filter pressure in Step 11 above 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.
WINTERIZING YOUR FILTER
In areas that have freezing winter temperatures,pool equipment must be
winterized to protect against damage.
1.Backwash the sand filter.
2.After back washing,shut the pump off and move the handle of the valve
to the WINTER position.
Allowing water to freeze in the system will damage the system and
cause potential water damage/flooding and potential property damage

- 16 -
3.Remove the drain cap on the bottom of the filter tank and leave the cap
off during winter.Completely drain the filter tank.
4.Drain and winterize the pump.
5.Drain all appropriate system piping.
WINTERIZING YOUR FILTER TROUBLESHOOTING
Pool water is not
sufficiently clean.
1.Pool chemistry is not
adequate to inhibit algae
growth.
2.Improper amount or
wrong sand size.
3.Inadequate turnover rate.
1.Maintain pool chemistry
or consult a service
technician.
2.Check sand bed depth
and sand size or consult
a pool service technician.
3.Run the system for a
longer time or consult a
dealer or pool service
technician.
Control Valve leakage
1.Control Valve is set
between two functions.
2.The gasket is broken.
1.Set the valve to the
correct function.
2.Replace the gasket.
