“READ ALL INSTRUCTIONS” Failure to follow these important
safety instructions and other basic safety precautions may result
in serious personal injury.
Before you begin installing your filter, refer to your pump
owners guide for very important installation and electri-
cal information related to your filter.
ELECTRICAL/BUILDING PERMIT
Local building codes may require obtaining an electrical
or building permit and may have regulations on set
backs and barriers that must be followed.
ELECTRICAL
We recommend you have a qualified electrical contrac-
tor install the electrical power supply as specified in your
pump instructions.
INSTALLED LOCATION
Position filter, pump and any other related components
a minimum of 5 feet from pool to prevent their being
used as a means to climb into the pool by young chil-
dren. DO NOT store toys, chairs, tables, containers or
other objects within 5 feet of the pool for the same
reason.
WARNING
SEVERE ELECTRICAL SHOCK could result if you
install your filter and pump on a deck or above pool
water level. They could fall into the water, causing
severe shock or electrocution. DO NOT install on a
deck or other surface at, above or slightly below the top
rail of the pool.
PROPERLY SUPPORTED
Filter, pump and any other related components should
be properly supported to prevent damage from misalign-
ment, settlement, vibration and mounted so as to
minimize the potential for the accumulation of debris and
moisture.
ACCESSIBILITY
The circulation system components should be installed
to allow accessibility for inspection, repair or replace-
ment.
DO NOT alter the pump electrical cord in any way or
change the plug end to any style.
DO NOT use an extension cord(s). Severe electrical
shock may occur.
PREVENT SEVERE SHOCK
To prevent the risk of severe electrical shock, plug your
pump cord end into a grounding type receptacle pro-
tected by a ground fault circuit interrupter (GFCI).
Contact a qualified electrician if you cannot verify that
the receptacle is protected by a GFCI.
IMPORTANT SAFETY INSTRUCTIONS
DO NOT allow children to operate or play around this
product unless they are closely supervised by adults at
all times.
Replace damaged cord immediately to reduce the risk of
electrical shock.
DO NOT BURY CORD
An exposed cord may accidentally become damaged or
severed by a sharp object or shovel resulting in severe
electrical shock. Position cord to prevent accidental
damage from lawn mowers, hedge trimmers or other
equipment.
BARE FEET/WET GROUND
This is a dangerous combination around electrical
equipment. Always be sure the ground under your feet
and body is dry before you touch electrical equipment.
Failure to heed this warning may cause severe personal
injury or electrocution due to severe electrical shock.
WARNING
Avoid direct water spraying with a garden hose around
electrical outlets, pump or any other electrical devices.
Severe electrical shock or electrocution may occur.
SERVICING YOUR PUMP
Always unplug your pump from the receptacle before
servicing, adjusting or repairing.
HAZARDOUS PRESSURE
Pumps, filters and other equipment/components of a
swimming pool filtration system operate under pressure.
Incorrectly installed and/or improperly tested filtration
equipment and/or components may fail resulting in injury
and/or property damage. A qualified pool professional
MUST conduct all pressure tests. This product is
intended for above-ground/on-ground swimming pool
applications only. DO NOT connect to a high pressure
system such as a municipal water main. To prevent
explosion caused by entrapped air in the filtration
system, bleed all air from the system. Confirm that ALL
filtration system component clamps, bolts and covers
have been properly tightened.
SAVE THESE INSTRUCTIONS

injury or damage to the filter system. Starting at least
12" from the pool wall, make two 3-4" deep trenches,
one from the pool's skimmer toward the front of the
pump and the other from the pool's return fitting toward
the filter port located on the tank cover, marked "TO
POOL". Be sure the hoses are routed so that water flow
through them is not restricted.
POSITION FILTER ON TANK BASE
Position filter in the tank base with the tank port labeled
“TO PUMP” oriented to the pump discharge as shown
in Fig.s 1 or 2.
IMPORTANT: After orienting the filter on the pad, and
prior to filter start-up, you must install the tank o-ring.
Loosen the v-clamp and remove it and the cover. Install
the o-ring onto the tank flange. Reinstall the cover,
being sure that the o-ring is seated into the cover
groove. Reinstall the v-clamp and tighten.
Did you read the IMPORTANT SAFETY INSTRUC-
TIONS? If not, READ THEM NOW. They contain very
important safety information related to the installation of
your filter.
Familiarize yourself with the installation sequences by
reading these instructions first. AVOID SHORTCUTS
that may result in reworking the installation.
BEFORE YOU BEGIN
The pool must be properly erected per your pool
assembly 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
securely tightened.
TOOLS REQUIRED
• Flat head screwdriver
• Crescent wrench
• Measuring tape
• Carpenters level
• Flat nose shovel
• Rags
• 5/16" Nutdriver (optional)
The following tools are required for hard plumbing:
• Hack saw
• File
MATERIALS REQUIRED
• Nine 12" x 12" patio blocks (All filters)
The following materials are required for hard plumbing.
• 1-1/2" Schedule 40 PVC pipe
NOTE: Quantity depends on length of pipe
runs desired.
• 10 to 12 1-1/2" 90 degree socket PVC elbows
• PVC pipe primer
• ABS to PVC solvent cement with applicator
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 of the circulation
lines may occur during wet seasons. Position patio
blocks as shown in the following illlustrations, using a
shovel and carpenter’s level to level ground before
placing the blocks.
POSITIONING FILTER/PUMP
Position filter and pump on pad as shown in Fig. 1 for
hose installation, hoses not included, or Fig. 2 when

2. Plug in your pump to the GFCI protected receptacle.
Refer to “WARNINGS”.
3. Start pump. Check all fittings and hose connections
for leaks and correct if necessary. Note the pres-
sure reading on the pressure gauge. Clean the
cartridges when the pressure has increased 5
pounds over the clean cartridge filter pressure.
FILTER OPERATION
Because all pool installation environmental conditions
are so variable (wind, rain, airborne debris, heat, and
pool use, etc.), it is difficult to provide an accurate
normal filtering time for normal usage. You must
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. Consult your local pool store for helpful advice
in keeping your pool clean and sanitary.
HARD PLUMB INSTALLATIONS
Use 1-1/2" Schedule 40 PVC pipe. Cut pipe to length as
required between the joints. With ends cut square,
remove any burrs and loosely assemble for proper fit
prior to solvent welding. Slip the union nut (25) onto the
pipe with the female threads facing the union adaptor
(3). Then, solvent weld the union socket (24) onto the
pipe using primer and PVC/ABS solvent cement. DO
NOT Allow solvent cement to contact the sealing
surface of the union socket. When dry, assemble the
threaded connections and tighten firmly by hand.
Insert the o-ring (27) into the union adaptor groove, then
secure the cemented pipe assembly onto the union
adaptor (3) with the union nut (25).
SOLVENT WELDING
Contact your pool dealer for ABS to PVC Solvent, PVC
Cement, and PVC Primer. Follow directions on the
labels.
Typical Hard plumb return installation
INITIAL START UP
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.
Excessively contaminated water with suspended
particles and algae, may require you to clean the
cartridges once or twice during this initial stage of
filtering the new raw water. After this initial filtering
stage, the cartridge cleaning process will be less
frequent and will allow longer time periods between
cartridge cleanings.
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
over tighten.
When possible, avoid operating your filter during peak
times for electricity demands in your community. Check
with your local electric utility company for their recom-
mendation on the best times for operating your filter and
pump.
WHEN TO CLEAN CARTRIDGES
When to clean the cartridges largely depends on local
environmental conditions and sudden changes in the
weather. Windy areas or a sudden high windy day,
spring time pollen releases, excessive pool use or
neglect in pool chemical treatment can cause your filter
to work harder to remove excess amounts of airborne
particulates. Check the pressure gauge reading
frequently and clean the cartridges when the pres-
sure gauge increases 5-7 PSI above the clean filter
starting pressure.
CLEANING CARTRIDGES
As the cartridges become saturated with dirt and debris,
the return flow back to the pool will slow. To clean the
cartridges, follow the steps below:
1. STOP PUMP and unplug from receptacle.
2. PLUG SKIMMER AND RETURN
To prevent the backflow of pool water from exiting
the filter tank when the cover is removed, stuff a rag
into the following openings:
A - Inside skimmer, bottom hole.
B - Return inlet fitting opening (from inside of pool).
3. DRAIN TANK
Remove the tank drain cap. Allow the tank to start
draining. The drainage flow will increase when the
tank cover is removed.
4. DISCONNECT HOSE/PIPING
Loosen the return line hose clamp at the the tank
cover connection. Remove end of hose from fitting.
5. REMOVE TANK COVER
Loosen the v-clamp knob counterclockwise and
remove the clamp. Lift cover straight up until clear.
Note: Hard plumbed lines (if used) may have to be
shifted to one side in order to clear cover from tank.
Set aside, taking care not to scratch or dent the o-
ring sealing surface on cover. Remove tank o-ring
from tank flange. Allow tank to drain completely.
6. REMOVE CARTRIDGE LOCATOR
Grip the center pipe coupling and unscrew counterclock-
wise. Lift it and cartridge collector out of the tank.

5
7. LIFT OUT CARTRIDGES
Carefully rotate and lift out each cartridge, taking
care not to damage the cartridge's pleated material.
CAUTION: Never lay the side of a cartridge on a
rough textured surface such as concrete, asphalt,
gravel, etc.. Damage to the pleated filtering material
may occur. THIS WILL SERIOUSLY REDUCE
FILTERING PERFORMANCE.
8. FLUSH OUT TANK
With a garden hose, flush out tank through the drain
and remove any large debris that may have passed
through the skimmer and/or pump strainer baskets
into the filter.
9. CLEAN CARTRIDGES
Attach the BLASTER NOZZLE to a garden hose.
Position cartridge in an upright position, supporting
with one hand when cleaning. Hold the blaster
nozzle away from the cartridge about 18". Starting
at the top of the cartridge, spray between each
pleat, working downward.
10. SOLUTION CLEAN CARTRIDGES
NOTE: Before solution cleaning the cartridges, be
aware that chlorine and acids kill lawns and plant
life. Clean the cartridges in a suitable area.
Always wear protective clothing such as gloves
and goggles.
If the cartridge becomes impregnated with algae,
pour a mild chlorine solution (1 part chlorine to 4
parts water) over all pleated surfaces and let soak
for 10 minutes. Hose off thoroughly. Then, mix a
solution of warm water and detergent (1 cup per 5
gallons of water). Then add one cup of chlorine or
household bleach to the solution.
Totally submerge and soak the cartridges for 15-30
minutes. Agitate the cartridges vigorously to
dislodge trapped particles.
11. RINSE
Rinse cartridges thoroughly before reinstalling in the
filter. Soapy bubbles will appear on the pool surface
near the return fitting if the cartridges are not rinsed
clean,.
12. HARD WATER
Hard water will eventually coat the cartridges with
calcium deposits that cut off good filtering perfor-
mance. To correct, mix a solution (1 part muriatic
acid to 4 parts water). With the cartridges fully
submerged, soak them for about 15 minutes. Rinse
thoroughly with clean water.
NOTE: Muriatic acid solution will kill lawns and
plant life. Perform this service in a suitable
area.
13. Reverse procedure for re-assembly.
14. RESUME NORMAL OPERATION
Start pump and check for any leaks around cover,
tank drain, and all connections. Correct if neces-
sary.
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. Always keep moving
parts lubricated and maintain 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
plastics. DO NOT use petroleum based lubricants.
Many people consider “PETROLEUM JELLY” safe for
babies and can be applied to anything. But, it will
DESTROY most plastics and o-rings. Silicone lubri-
cants available at your pool dealer are safe for use on
plastics and o-ring seals.
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 the filter is not properly as-
sembled. See your dealer for original replacement
parts.
CAUTION
BEFORE removing the filter or pump from pool area for
servicing, always disconnect the pump from its electrical
source and prevent the backflow of water from your
skimmer and return fitting ports from flowing out of the
disconnected hoses.
1. Remove skimmer cover and basket and plug the
port at the bottom of the skimmer with a rag.
2. Referring to the instructions for your return fitting,
install the Shutoff disc. Option: stuff a rag into the
return fitting opening.
3. Disconnect hoses on the filter or pump as neces-
sary when removing for service or repairs.
DRAIN TANK
See Caution Above
1. Remove tank drain cap to drain.
2. Remove v-clamp, cover, and large o-ring from tank.
3. After servicing, reassemble and install in reverse.
Make sure tank's o-ring and sealing areas are free
of any dirt or grit, and that the o-ring is lubricated
with silicone lubricant. Be sure that the o-ring is
evenly seated in the cover groove before replacing
the cover and v-clamp.
WINTERIZING FILTER
In areas subject to freezing damage, it is mandatory
that the filter, pump and any related components be
removed from the pool area and stored indoors. (Refer
to the individual components owner's guide such as
pump, skimmer, chlorinator, etc., for specific winterizing
instructions.)
1. Siphon water level down below skimmer opening by
using your vacuum hose and allow the water to flow
to an area that can accept a thousand gallons or
more.
2. Drain the tank completely.
3. Disconnect all line connections.
4. Remove v-clamp from the filter and remove the
cover and gasket.
5. Remove cartridges, flush out tank, clean the car-
tridges thoroughly and allow to dry completely. Turn
the tank upside down to allow the water to drain
out of the manifold assembly.
6. Reinstall the cartridges only after they have dried
completely. Replace the cover and drain cap.
7. Store all components in a warm dry area indoors.
