BEFORE YOU BEGIN
The pool must be properly erected per your pool assem-
bly and installation instructions before installing the filter.
Install the surface skimmer and return fitting.
Before completing the filling of the pool to the water
level indicator marks on the skimmer face plate, the filter
and pump should be installed with all connections
secured tightly.
TOOLS REQUIRED
• Flat head screwdriver
• Flat shovel
• Measuring tape
• Carpenter level
MATERIALS REQUIRED
• Nine 12" x 12" patio blocks
• Waste hose - 1-1/2" inside diameter
• Medium sized rubber band (3" long)
• Ordinary plastic bag
• 100 lbs. #20 grade filter sand
• 1-1/2" hose clamp
• Silicone lubricant (available at pool dealer)
INSTALLATION
INSTALLATION LOCATION
Install your filter and pump and any other related
components at least 4 feet from the pool to prevent their
being used as a means of access to the pool by young
children. Patio blocks provide firm support and keeps
standing water and weeds away from electrical parts.
DO NOT install your filter and pump directly on the
ground surface. Settling and stressing circulation lines
may occur during wet seasons. Position patio blocks as
illustrated, use a shovel and carpenter’s level to level
ground before placing the blocks.
POSITIONING FILTER/PUMP
Position the filter and pump as shown in FIG. 1.
INSTALL HOSES
(See Fig. 1 and Exploded Parts Illustration)
FIG. 1
Suction and return lines should be partially buried to
prevent accidental tripping that could cause personal
injury or damage to the filter system.
Be sure the hoses are routed so that water flow through
them is not restricted.
Starting at least 12" from the pool wall, make two 3-4"
deep trenches, one from the pool skimmer to the front
of the pump and the other from the pool return fitting to
the filter valve return port (located at the bottom of
valve).
The two 8 ft. long hoses (Items 29) are interchangable
and used for the suction and return lines. Slip a hose
clamp over the ends of each hose prior to installing.
Connect one long hose (suction line) between the pool
skimmer and front port of the pump. Connect the other
long hose (return line) between the pool return fitting
and valve return port (located on the lower end of valve).
Connect the short hose (Item 28) between the pump
discharge port (located at top of pump) and the filter
valve pump port (located on the center left side of the
valve). Tighten clamps firmly using a flathead
screwdriver or 5/16" nutdriver. Cover the trenches with
a firm board when finished.
NOTE: Do not completely bury the hoses with dirt.
ELECTRICAL OUTLET
Refer to your pump owners guide for detailed informa-
tion pertaining to the requirements and regulations for
safe electrical installation of the power supply, recep-
tacle outlet, switching and ground fault interrupter.
IMPORTANT: Incorrect hose hook-up could cause
damage to your filter system. Follow the instructions
below carefully.

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.

5
VACUUMING YOUR POOL
When vacuuming your pool, depris is caught in the filter
at a very rapid rate. Consequently, the filter must work
harder, causing a rapid increase in filter pressure as will
be indicated on the pressure gauge. Frequent back-
washing could be necessary during this process de-
pending on the amount of dirt being vacuumed off the
pool floor. Keep a check on the pool water level and
refill as required.
MAINTENANCE
Preventative maintenance will provide continued smooth
performance and extend the life of your filter for many
years. Neglect will cause parts to wear or bind, leaks to
occur and result in costly repairs. Keep moving parts
lubricated and a clean environment around your filter
and related components.
LUBRICATION
There are various types of lubricants available.
However, most are intended for moving metal parts.
Unfortunately, these lubricants will harm or degrade the
plastics. DO NOT use petroleum base lubricants. Many
people consider “PETROLEUM JELLY” safe for babies
and can be applied to anything. But, it will DESTROY
most plastics. Silicone lubricants, available at your pool
dealer, are safe for use on plastics.
LUBE VALVE SHAFT AND O-RING
Periodically lubricate the valve shaft and internal
o-rings in your filter valve to maintain smooth
operations.
1. Stuff a rag in the return fitting and into the bottom
inside outlet of your skimmer to reduce water back-
flow exiting the valve body when the piston assem-
bly is removed.
2. Unscrew valve cover and pull piston assembly up
and out of valve body.
3. Lightly lubricate the piston o-rings and valve shaft
with silicone lubricant.
4. Reinstall piston assembly and remove rags from
skimmer and return fitting.
5. Actuate piston assembly up and down to distribute
the lubricant, then resume normal operations.
REPAIRS
Servicing should be performed by a qualified dealer. If
disassembly is attempted, mark each of the parts
assembled position as it relates to its mating parts. This
assures proper alignment when reassembled.
Malfunction will occur if not properly assembled. See
your dealer for original replacement parts.
CAUTION
BEFORE removing filter or pump from pool for servic-
ing, prevent the backflow of water from your skimmer
and return inlet from flowing out of disconnected hoses.
1. Remove skimmer cover and basket and plug inside
bottom hole with rag.
2. Referring to the instructions for your return inlet,
remove the inlet cover and eye ball. Insert the
winterizing disc and reinstall the cover.
3. Disconnect hoses on filter or pump as necessary
when removing for service or repairs.
DRAIN TANK
See Caution Above
1. Remove V-Clamp from filter and remove cover and
o-ring.
2. Remove tank drain cap to drain.
3. Place plastic bag over distributor in tank and secure
with a rubber band. Scoop out sand with a medium
size can and place in plastic bag.
4. After servicing, reassemble and install in reverse.
Make sure tank o-ring and sealing areas are free of
any sand and that the o-ring is properly seated in
the cover groove before replacing cover.
WINTERIZING FILTER
In areas subject to freezing damage, it is mandatory that
the filter, pump and any related components be re-
moved from the pool and stored indoors. (Refer to
individual components owner's guide such as pump,
skimmer, chlorinator, etc., for specific winterizing
instructions.)
1. Backwash the filter.
2. Siphon pool water level down below skimmer
opening by using your vacuum hose and allow
water to flow to an area that can accept a couple of
thousand gallons or more.
3. Remove V-Clamp from filter and remove cover and
o-ring.
4. Remove tank drain cap and allow tank to drain fully.
5. Disconnect all hoses.
6. Place plastic bag over distributor in tank and secure
with a rubber band. Scoop sand out with a medium
size can and place in plastic bag. If sand is not
badly contaminated, save for next season.
7. Store all components in a warm dry area indoors.
