INSTALL SAND
Gently pour 100 lbs. of filter sand into tank and level
surface with palm of hand. Remove any sand from
plastic bag and tank flange sealing surface. Remove
rubber band and plastic bag.
REINSTALL COVER
Position large O-Ring on tank flange sealing surface and
place cover on top, aligning O-Ring into cover groove.
Install V-Clamp, sandwiching cover and tank flanges.
Tighten knob until ends of clamp are approximately 3/8"
apart.
FINISH FILLING POOL
Finish filling your pool, referring to skimmer installation
and pool assembly instructions for proper water level.
WASTE LINE HOOK-UP
The discharge waste water will contain pool water
treatment chemicals that may harm certain plants and
vegetation. Therefore, position the discharge end of the
waste line in a safe, out-of-sight area capable of accept-
ing 150 to 200 gallons of waste water. Install a 1-1/2"
inside diameter waste discharge hose (not supplied) on
the waste port, located on the valve. Slip a 1-1/2" hose
clamp (not supplied) over one end of the hose. Then,
push hose onto the port fully and tighten clamp firmly.
INSTALL FILTER SAND
Your filter is designed to provide peak performance
using #20 grade filter (.4/.5 mm) sand. The sand should
be uniform in size and appear as crushed sand with
sharp edges. Rounded river bed sand will impair
filtering performance. Consult your local pool store.
REMOVE COVER CLAMP
Unscrew V-Clamp knob counter-clockwise to loosen and
remove clamp.
REMOVE COVER
Lift cover off tank. Remove large O-Ring.
COVER DISTRIBUTOR
Slip a plastic bag over the distributor and secure with
rubber band .
VALVE OPERATION
Your new filter has two positions of operation, which are
explained below. To change positions of the valve,
make sure the pump is off.
FILTERING: Pull handle to the full up position for
filtering or vacuuming pool.
BACKWASH: Push handle to the full down position for
backwashing (cleaning) filter. Water is discharged to
waste through the top valve port. Use for two minutes
or until water runs clear.
INITIAL START UP
Before you begin filtering your pool, the filter sand must
be backwashed thoroughly to remove the extra fine
sand grains normally found in new filter sand.
1. Loosen the pump strainer pot lid to allow air to
escape. Tighten lid when water begins to flow
between strainer pot lid and strainer body. Do not
overtighten.
2. Plug in your pump to the GFCI protected receptacle.
Refer to WARNINGS.
3. Push valve handle down against the valve cover in
the BACKWASH position.
4. Start pump. During this initial start-up allow 4-5
minutes to flush out the super-fine sand grains to
prevent them plugging the underdrain slots. Be-
cause pool water is lost during this operation (100 to
150 gallons) keep a close check on pool water level.
Never let water level get so low that no water flows
to pump. Refill pool as required.
5. Stop pump. Pull valve handle up into the full up
position to the FILTER position and start pump.
Note the pressure reading on your pressure gauge
for future reference of when to backwash.
6. Check all fittings and hoses for leaks and correct if
necessary.
FILTER OPERATION
A newly filled pool is normally filled with unfiltered water
and usually requires continuous filtering for 24 to 48
hours along with chemical treatment of the pool water.
Because all pool installations vary in environmental
conditions (wind, rain, airborne debris, heat and pool
use, etc.), it is impossible to provide an accurate filtering
time for normal usage. Use a trial and error method to
determine how long your filter must operate each day.
Generally, 6 to 8 hours of filtering each day is sufficient
to maintain pool clarity if the pool chemical treatment is
correct.
As the water clears, less backwashing will be required.
Consult your local pool store for helpful advice in
keeping your pool clean and sanitary.
When possible, avoid operating your filter during peak
electricity demands in your community. Check with your
local electric utility company for the best times they
recommend for operating your filter pump.
WHEN TO BACKWASH
As your filter removes debris from the pool water during
the filtering process, the return flow will gradually
reduce. Backwash when the pressure gauge increases
5 to 7 pounds above the clean filter starting pressure.
