THIS SYSTEM OPERATES UNDER HIGH PRESSURE
When any part of the circulating system, (e.g., closure, pump, lter, valve(s), etc.), is serviced, air can enter the system
and become pressurized. Pressurized air can cause the top closure to separate which can result in severe injury, death,
or property damage. To avoid this potential hazard, follow these instructions:
1. Let air and pressure out of system before and after servicing.
a. Shut off pump and RELIEVE PRESSURE by opening the manual air/pressure relief valve before
servicing, including before tightening the clamp bolt. Follow the Opening the Filter, page 4
instructions exactly.
b. Follow the start-up instructions given Start-Up Instructions on page 6 exactly after completing
service. The air/pressure relief valve must remain open until water comes out, allowing all air out
of the system.
2. Install lid and clamp ring properly.
a. Follow the Installing the Filter Lid and Clamp Ring on page 5 instructions exactly. The nut must
be tightened until the spring is compressed when clamp is installed. Tap the clamp with a rubber
mallet or similar tool after clamp installation to ensure proper seating.
3. Maintain circulation system properly to help prevent air entering the system.
a. Replace worn or damaged parts immediately, (e.g., closure, pressure gauge, valve(s), O-rings, etc.).
b. Maintain proper water level in the pool or spa.
4. Verify that the return line to the pool is unobstructed. Ensure return valves are open and any winterizing
plugs are removed.
Your lter is a piece of machinery, do not tamper with it, attempt to disassemble it or otherwise adjust it unless you fully
understand it's operation. Serious injury or death can occur if the equipment is improperly handled. Consult a pool
service professional for maintenance and service assistance.
Always disconnect power to the pool circulating system at the circuit breaker before servicing the lter. Ensure that
the disconnected circuit is locked out or properly tagged so that it cannot be switched on while you are working on the
lter. Failure to do so could result in serious injury or death to serviceman, pool users or others due to electric shock.

When to Clean Your Filter
A lter's operating pressure increases as dirt is ltered from your pool. This buildup of pressure will vary due to di󰀨erent
bathing loads, temperature, environmental conditions, etc.
Clean your lter when the lter's pressure gauge reads approximately 10 psi higher than the Original Starting Pressure
or when signicant reduction in ow is noticed. When using a variable speed pump the Original Starting Pressure will
be dependent on the pump speed (RPM) when recording the original operating pressure.
Opening the Filter
Follow these instructions exactly to prevent the lid from separating during system start-up, operation or servicing.
This lter operates under high pressure. Air can also enter the system and become pressurized.
If there is air in the system, there will be positive pressure that could cause the lid to separate from the lter when you
release the clamp or during system start-up or operation.
If there is no air in the system, there may be negative pressure, which would make the system hard to open.
Follow these instructions exactly. Opening the relief valve equalizes the pressure and releases any trapped air within
the system, making it safe and easy to open.
RECOMMENDED EQUIPMENT:
• Socket Wrench
• 7/8-inch Socket
• Socket Extender (if needed)
PROCEDURE:
1. Shut o󰀨 pump and relieve all pressure from the
ltration system.
a. Turn the pump OFF, shut OFF any automatic
controls (e.g., timers), and disconnect power at
the circuit breaker to ensure that the system is
not inadvertently started during maintenance.
b. Open the Manual Air Relief Valve by turning the
top of the valve 1/4 turn counterclockwise until it
snaps into the full open position.
c. Stand clear of the lter and wait until all pressure
is relieved. Pressure gauge must read zero (0)
psi.
2. Open the drain plug at the bottom of the lter and
allow all water to drain from the lter.
3. Using a 7/8-inch wrench, loosen the clamp barrel nut,
allowing the spring coils to decompress. See FIGURE
2.
4. Remove the barrel nut, spring and two washers from
the T-bolt and place them aside.
5. Remove the clamp ring from the lter and place it
aside.
6. Carefully lift the lter lid away from the tank bottom.
DO NOT lift the lter lid by the air relief valve. This can damage the valve.
Note: If the lid is tightly sealed to the tank bottom you may have to gently wiggle the lter lid side to side to
separate the tank halves. DO NOT use a screwdriver or pry-bar to lift the lid. This can damage the O-ring.
7. Place the tank lid and O-ring in a safe place where it will not be damaged while performing maintenance.
Note: Minimize the amount of debris that comes in contact with the tank O-ring while it is exposed.

Cleaning the Filter Cartridges
1. Follow Opening the Filter on page 2 exactly.
2. Remove the pump strainer pot lid and clean the pump strainer
basket. Reinstall the strainer basket and lid.
3. Remove the Compression Spring and Spring Adapter from the
Top Manifold.
4. Remove the Top Manifold from the lter cartridges and lay the
manifold aside. See FIGURE 3.
5. Carefully remove each cartridge separately.
6. Using a garden hose with a straight ow nozzle, hold the nozzle
at a 45-degree angle to the cartridge and wash the entire
cartridge from top to bottom (see FIGURE 4).
Note: Pay special attention to the area between pleats.
7. For cartridges used in pools where high levels of perspiration,
suntan lotions or other oils are present:
a. Soak the cartridge for at least one hour in one of the
following:
• A commercial lter cleaner
Heed all manufacturers' instructions and warnings when using
polyhexamethylene biguanide sanitizers or other cartridge lter cleaner
solutions.
• 1 cup trisodium phosphate (TSP) to 5 gallons of water
• 1 cup dishwasher detergent to 5 gallons of water
b. Thoroughly rinse each cartridge to remove oils and cleaning solution.
Failure to remove all oils and cleaning solutions before acid soaking will result in
permanent restriction of water ow through the lter and will cause premature
cartridge failure.
8. Wash out the inside of the lter tank and bottom manifold. Water and debris will drain
out through the open drain plug.
9. Inspect the gasket around the outer lip of the bottom plate. The gasket must be rmly
and evenly seated around the entirety of the outer lip.
10. Place the bottom manifold, cartridges and top manifold into the tank, ensuring the
spring and standpipe assembly are retained on the top manifold.
11. Ensure the O-ring is clean and seat it onto the tank bottom.
12. To acid soak the cartridges, continue to Acid Soaking the Filter Cartridges, page 9 or to close the lter, refer to
Reinstalling the Filter Lid and Clamp Ring, page 5.

Acid Soaking the Filter Cartridges
After an extended period of operation, it may be necessary to soak the cartridges in an acid solution. Acid soaking will
remove algae, calcium carbonate, iron and other mineral build-ups from the cartridges. If not removed, these mineral
deposits can lead to the restriction of water ow through the lter and can impede e󰀩cient operation of the equipment.
Muriatic acid is corrosive and can lead to inammation or burns to body tissue.
ALWAYS wear rubber gloves, safety glasses and an N-95 dust mask when handling acid to prevent serious bodily injury.
To prevent degradation of the acid by UV light, store muriatic acid in an opaque container and away from direct sunlight.
RECOMMENDED EQUIPMENT:
• Large Plastic Container
• Garden Hose with a Straight Flow Nozzle
• Muriatic Acid (stored in opaque container)
• Rubber Gloves
• Safety Glasses
• N-95 Dust Mask
PROCEDURE:
1. Remove all oils and cleaning solutions from the cartridges.
Acid soaking without performing this step will result in permanent restriction of water ow through the lter and
premature cartridge failure.
2. Put on protective equipment - rubber gloves, safety glasses and
N-95 dust mask.
3. In a large plastic container, create a solution of one part muriatic
acid to twenty parts water. See FIGURE 5.
Always introduce the muriatic acid as close to the water's
surface as possible. This will minimize splash and reduce
the risk of user contact with the acid.
4. Gently place the bottom of the cartridges into the acid solution.
Allow the cartridges to soak in the solution for 10 minutes, or
until bubbling stops.
5. Turn the cartridges over, placing the top halves into the solution.
Allow the top halves of the cartridges to soak for 10 minutes, or
until bubbling stops.
6. Remove the cartridges from the acid solution.
7. Using a garden hose with a straight ow nozzle, thoroughly
wash down the entire lter element. Wash from the top down,
holding the nozzle at a 45-degree angle to the cartridge. See
FIGURE 4, page 4.
8. Reinstall the cartridges and dispose of the acid solution in
accordance with local regulations.
9. Follow Reinstalling the Filter Lid and Clamp Ring on page 5 exactly.

month to ensure proper tension. If spring coils
do not touch then shut o󰀨 pump and relieve
pressure and tighten the nut and tap lter clamp
until the coils touch.
Reinstalling the Filter Lid and Clamp Ring
RECOMMENDED EQUIPMENT:
• Socket Wrench
• 7/8-inch Socket
• Socket Extender (if needed)
• Rubber Mallet
PROCEDURE:
1. Ensure the O-ring is clean and properly seated on the
tank bottom. Seat the lter lid onto the tank bottom so
the O-ring ts in between the tank halves.
2. Hold the ends of the clamp ring apart and place over
both upper and lower tank anges. Bring the ends of
the lter clamp together.
3. Insert the T-bolt through the other side of the clamp and
hold together.
4. Place the small washer onto the T-bolt.
5. Place the spring, large washer and barrel nut onto the
T-bolt and tighten the nut by hand. Ensure the clamp
ring ts easily on the tank anges.
6. After tightening by hand:
a. Use a 7/8-inch socket wrench to tighten further.
b. Tap around the entire clamp ring with a rubber
mallet (or similar tool) multiple times to t the
clamp properly.
c. Continue to tighten until the spring coils touch.
d. Tap around the entire clamp again and verify the
spring coils remain touching. If not, continue to
tighten the nut.
Note: The clamp is installed correctly only when the
spring coils remain touching after tapping the clamp. See
FIGURE 6.
7. Close the drain plug at the bottom of the lter.
8. Follow Start-Up Instructions, page 6 exactly.
Follow these instructions exactly to prevent the lid from separating from the lter during system start-up or operation.
DO NOT tighten the nut or attempt to adjust the clamp ring or lid while the system is turned on or under pressure. This could
cause the lid to separate from the lter.
