reliable service when installed, operated and maintained according to the
information in this manual and the installation codes referred to in later
sections. Throughout the manual, safety warnings and cautions are identified
by the “ ” symbol. Be sure to read and comply with all of the warnings and
cautions.
Do not operate the filter until you have read and understand clearly all the
operating instructions and warning messages for all equipment that is a part
of the pool circulating system. The following instructions are intended as a
guide for initially operating the filter in a general pool installation,
however each installation may have unique conditions where the starting
procedure could be different. Failure to follow all operating instructions and
warning messages can result in severe injury, death, or property damage.
Do not permit children to use or operate this filter.
Use only a PTFE or silicone based lubricant when lubricating the O-rings on the union and bulkhead couplings. Use of petroleum based products will damage the equipment.
FILTER OPERATES UNDER HIGH PRESSURE.
When any part of the circulating system, (e.g., clamp, pump, filter, valve(s),
etc.), is serviced, air can enter the system and become pressurized.
Pressurized air can cause the lid to separate which can result in severe
injury, death, or property damage.
To avoid this potential hazard, follow these instructions:
- Before repositioning valve(s) and before beginning the assembly, disassembly, or adjustment of the clamp or any other service of the circulating system: (A) Turn the pump OFF and shut OFF any automatic controls to ensure the system is NOT inadvertently started during the servicing; (B) open the manual air relief valve; (C) stand clear of the filter; (D) wait until all pressure is relieved.
- Whenever installing the filter clamp FOLLOW THE FILTER CLAMP INSTALLATION INSTRUCTIONS EXACTLY.
- Once service on the circulating system is complete FOLLOW SYSTEM RESTART INSTRUCTIONS EXACTLY.
- Maintain circulation system properly. Replace worn or damaged parts immediately, (e.g., clamp, pressure gauge, valve(s), o-rings, etc).
- Be sure that the filter is properly mounted and positioned according to instructions provided.
Due to the potential risk that can be involved it is recommended that the pressure test be kept to the minimum time required by the local code. Do not allow people to work around the system when the circulation system is under pressure test. Post appropriate warning signs and establish a barrier around the pressurized equipment. If the equipment is located in an equipment room, lock the door and post a warning sign.
Never attempt to adjust any closures or lids or attempt to remove or tighten bolts when the system is pressurized. These actions can result in a separation or failure of system components. This instantaneous release of energy can cause components to be accelerated to high velocities and to travel far distances. These components could cause severe personal injury or death if they were to strike a person.
Never exceed the maximum operating pressure of the system components. Exceeding these limits could result in a component failing under pressure. This instantaneous release of energy can cause the closure to separate and could cause severe personal injury or death if they were to strike a person.
RISK OF ELECTRICAL SHOCK OR ELECTROCUTION.
This filter must be installed by a qualified service professional in
accordance with the National Electrical Code and all applicable local codes
and ordinances. Always disconnect power to the equipment at the circuit
breaker before servicing any of the equipment. Ensure that the disconnected
circuit is locked out or properly tagged so that it cannot be switched on
while you are working on the pool equipment. Failure to do so could result in
serious injury or death to serviceman, pool users or others due to electric
shock.
Position the filter and the air relief valve to safely direct water drainage and purged air or water. Water discharged from an improperly positioned filter or valve can create an electrical hazard that can cause severe personal injury as well as damage property.
This filter is intended for use in swimming pool applications. Most states and local codes regulate the construction, installation, and operation of public pools and spas, and the construction of residential pools and spas. It is important to comply with these codes, many of which directly regulate the installation and use of this product. Consult your local building and health codes for more information.
SERIOUS BODILY INJURY OR DEATH CAN RESULT IF THIS FILTER IS NOT INSTALLED AND USED CORRECTLY.
INSTALLERS, POOL OPERATORS AND POOL OWNERS MUST READ THESE WARNINGS AND ALL INSTRUCTIONS BEFORE USING THIS FILTER.
HAZARDOUS PRESSURE: STAND CLEAR OF PUMP AND FILTER DURING START UP Circulation systems operate under high pressure. When any part of the circulating system (i.e. clamp ring, pump, filter, valves, etc.) is serviced, air can enter the system and become pressurized. Pressurized air can cause the pump housing cover filter lid and valves to violently separate which can result in severe personal injury or death. Filter tank lid and strainer cover must be properly secured to prevent violent separation. Stand clear of all circulation system equipment when turning on or starting up pump.
Before servicing equipment, make note of the filter pressure. Be sure that all controls are set to ensure the system cannot inadvertently start during service. Turn off all power to the pump.
IMPORTANT : Place filter manual air relief valve in the open position and wait for all pressure in the system to be relieved.
Before starting the system, fully open the manual air relief valve and place all system valves in the “open” position to allow water to flow freely from the tank and back to the tank. Stand clear of all equipment and start the pump.
IMPORTANT : Do not close filter manual air relief valve until all pressure has been discharged from the valve and a steady stream of water appears. Observe filter pressure gauge and be sure it is not higher than the pre-service condition.
For Installation of Electrical Controls at Equipment Pad (ON/OFF Switches,
Timers and Automation Load Center)
Install all electrical controls at equipment pad, such as on/off switches,
timers, and control systems, etc. to allow the operation (startup, shut-down,
or servicing) of any pump or filter so the user does not place any portion of
his/her body over or near the pump strainer lid, filter lid or valve closures.
This installation should allow the user enough space to stand clear of the filter and pump during system start-up, shut down or servicing of the system filter.
The following information should be read carefully since it outlines the proper manner of care and operation for your filter system. As a result of following these instructions and taking the necessary preventative care, you can expect maximum efficiency and life from your filtration system.

General Operation Information
Read and follow all instructions and warnings before installing or servicing your filter. Proper installation and operation can prevent unnecessary repairs and maintenance.
Your filter 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.
1. The FullFloXF® C-Series Cartridge Filter operates under pressure and operates in a safe manner if clamped properly and without air in the circulating system.
2. The maximum working pressure of this filter is 50 psi. Never subject this filter to pressure in excess of this amount, even when conducting hydrostatic pressure tests.
3. Be sure the maximum pressure of the filter system does not exceed the maximum pressure of any components within the system during hydrostatic or external leak tests. Consult the maximum pressure stated on each component of the system.
4. The pressure gauge is the primary indicator of how the filter is operating. Maintain your pressure gauge in good working order (refer to Maintaining the Pressure Gauge).
Maintaining the Pressure Gauge
The pressure gauge is the primary indicator of how the system operates. It is critical to keep the pressure gauge in good condition.
Replace pressure gauge (P/N 190058) if any of the requirements below are not met:
1. Pressure gauge at zero (0) when pressure is relieved and system is turned
off.
2. Pressure gauge reads correctly while system is in operation.
3. The pressure gauge is readable and not damaged in any way.
Pressure Tests
When performing hydrostatic pressure tests or when testing for external leaks of the completed filtration and plumbing system, ensure that the Maximum Pressure that the filtration system will be subjected to DOES NOT EXCEED THE MAXIMUM WORKING PRESSURE OF ANY OF THE COMPONENTS CONTAINED WITHIN THE SYSTEM. In most cases, the maximum pressure will be stated on each component of the system.
If you do not know the pool or spa system operating pressure, install an ASME approved automatic Pressure Relief or Pressure Regulator in the circulation system set to the lowest working pressure of any of the components in the system.
INSTALLATION
This filter must be installed by a qualified pool technician in accordance with all applicable local codes and ordinances. Improper installation could result in death or serious injury to pool users, installers, servicers, or others and may also cause damage to property.

Anchor clamps hold the FullFloXF® C-Series Cartridge Filter to the equipment pad in order to withstand high winds caused during extreme weather, such as hurricanes.
To install the anchor clamps:
-
Ensure the filter is in its permanent location on the equipment pad.
-
Place the clamps into the base of the filter in the four (4) anchor slots shown in Figure 3.
Note: Bolts and bolt anchors are not included with the filter. The installer must provide 1/4″ x 1-3/8″ stainless steel anchor bolts and the appropriate size concrete anchor to mount the clamp to the equipment pad. Be sure to check local codes. -
Fit the hook of each clamp into the anchor slots on the base panel of the filter. See Figure 3.
-
Mark the position of the hole in each clamp on the equipment pad.
-
Use a masonry drill bit and drill a hole in the cement with a diameter as determined by the concrete anchor, at each of the marks on the equipment pad. The hole should be approximately 1.5 inches deep. See Figure 4.
-
Insert a bolt anchor into each of the holes. Be sure the anchors are set completely into the holes.
-
Position the anchor clamps so that the holes in the clamps are over the bolt anchors. Ensure the clamp hooks are over the lip of the filter base.
-
Insert an anchor bolt through each clamp into the bolt anchor and tighten to secure the clamp and filter to the equipment pad.
SYSTEM START-UP AND OPERATION
The following information should be read carefully since it outlines the proper manner of care and operation for your filter system. As a result of following these instructions and taking the necessary preventative care, you can expect maximum efficiency and life from your filtration system.
Opening the Filter
Follow these instructions exactly to prevent the lid from separating during system start-up, operation or servicing.
This filter 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 filter when you release the clamp or during system start-up or operation (see Important Warnings and Safety Instructions, page i-ii). 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.
REQUIRED TOOLS :
· Ratchet Wrench
· 7/8″ Socket
· Socket Extender (if needed)
PROCEDURE :
1. Shut off pump and relieve pressure.
- a. Turn the pump OFF, shut OFF any automatic controls (e.g., timers), and disconnect power to ensure that the system is not inadvertently started during maintenance.
- b. Open the HiFlow™ Manual Air Relief Valve by turning the valve cover assembly counterclockwise until it snaps into the full open position.
- c. Stand clear of the filter and wait until all pressure is relieved. Pressure gauge must read zero (0 psi).
2. Open the waste drain plug on the bottom of the FullFloXF® C-Series Cartridge Filter. Allow all water to drain from the bottom of the filter tank.
3. Loosen the clamp’s barrel nut with a 7/8″ wrench, allowing the spring coils to decompress. See Figure 6. Remove the barrel nut, spring and two washers from the T-bolt and place them in a safe place where they will not be lost.
4. Once the spring has fully decompressed the clamp assembly will rest in the open position. Carefully lift the filter lid straight up from the lower body of the filter. If the lid is tightly sealed to the filter body you may have to gently push the filter lid from side to side in order to separate the lid from the tank bottom.
DO NOT use the relief valve as a handle or lever since this may damage the valve.
5. Place the tank lid in a safe place where it will not be damaged while
performing any maintenance.
Note: Attempt to minimize the amount of debris that comes in contact with the
tank O-ring while it is exposed. This will help prolong the life of the
O-ring.
Installing the Filter Lid and Clamp Ring
Follow these instructions exactly to prevent the lid from separating from the filter during system start-up or operation. (See Important Warnings and Safety Instructions, page i-ii).
REQUIRED TOOLS :

b. Tap around the outside of the clamp ring with a rubber mallet (or similar tool) multiple times around the entire clamp to fit 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 7. -
Close the waste drain plug at the bottom of the filter.
-
Follow Start-Up Instructions exactly (see page 7).
Note : Check the spring coils at least once a month to ensure proper tension. If spring coils do not touch then shut off pump and relieve pressure and tighten the nut and tap filter clamp until the coils touch.
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 filter
Start-Up Instructions
THIS FILTER OPERATES UNDER HIGH PRESSURE.
When any part of the circulating system, (e.g., clamp, pump, filter, valve(s),
etc.), is serviced, air can enter the system and become pressurized.
Pressurized air can cause the lid to separate which can result in severe
injury, death, or property damage. To avoid this potential hazard, follow
these instructions:
1. Ensure the spring on the clamp ring is fully compressed, with coils touching.
2. Open the HiFlowTM Manual Air Relief Valve by turning the valve cover assembly a quarter turn counter-clockwise, until it snaps into the full open position. See Figure 8.
3. Stand clear of the filter tank, then start the pump.
4. Watch for proper operation. The system is not working properly if:
- a. The pressure gauge indicates pressure before water out-flow appears.
- b. A solid stream of water does not appear within 30 seconds after the pump’s inlet basket fills with water.
- c. Water leaks from where the two halves of the filter come together.
If any of these conditions exist, shut off the pump immediately. Open the manual air relief valve to relieve pressure and clean the valve (see Cleaning the Manual Air Relief Valve, page 8). If the problem persists, call Pentair Technical Service at 800-831-7133 for assistance.
5. After a steady stream of water appears, close the manual air relief valve by turning the valve cover assembly a quarter turn clockwise.
6. The first time the system is started up, fill out Table 2:
- a. Record the “Original Starting Pressure”
- b. Fill in the pressure at which to clean the filter (8-10 psi higher than the “Original Starting Pressure”).
- c. If the system includes a variable speed pump, record “Original Pump RPM”. “Original Starting Pressure” will be dependent on the pump speed (RPM).

FULLFLOXF® C-SERIES Cartridge Filter Installation and User’s Guide
When to Clean the Filter
Properly monitoring and cleaning the filter will prevent avoidable repairs and maintenance.
Clean your filter when pressure reads between 8-10 psi higher than the “Original Starting Pressure” recorded in Table 2 on page 7, or when significant reduction in flow is noticed. The pressure reading increases as it filters dirt from your pool. This build up of pressure will vary due to different bathing loads, temperature, environmental conditions, etc.
Cleaning the Filter Cartridges
1. Follow Opening the Filter (page 5) exactly.
2. Remove hair and lint strainer pot lid from the pump and clean basket. Replace strainer basket and secure strainer pot lid.
3. Remove the Air Bleed Screen Cap (1) from the Top Manifold (2). See Figure 10.
4. Clean all debris from the Air Bleed Screen Cap and reinstall onto the Top Manifold.
5. Separate the Top Manifold (2) from the filter cartridges and lay the manifold aside. See Figure 10.
6. Carefully remove each cartridge separately.
7. Using a garden hose with a straight flow nozzle, wash down the entire filter cartridge. Wash from the top down, holding the nozzle at a 45-degree angle to the cartridge (see Figure 11). Pay special attention to the area between pleats.
8. For cartridges used in pools or spas where high levels of perspiration, suntan lotions and other oils are present:
-
a. Soak the cartridge for at least one hour (overnight is most effective) in one of the following:
-
A commercial filter cleaner
Heed all manufacturers’ instructions and warnings when using polyhexamethylene biguanide sanitizers or other cartridge filter cleaner solutions. -
One cup trisodium phosphate (TSP) to five gallons of water
-
One cup dishwasher detergent to five gallons of water
-
-
b. Rinse the 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 flow through the filter and will cause premature cartridge failure.
9. If algae, calcium, iron or other mineral build-ups are present on the filter cartridges, acid soaking may be necessary. Refer to Acid Soaking the Filter Cartridges, on page 10, for specific instructions.
10. Direct the water spray to wash out the inside of the tank body. Water and debris will drain out through the open drain plug.
11. Place the four (4) cartridges back onto the support pipes in the bottom of the tank.
12. Reinstall the Top Manifold onto the cartridges and verify the Air Bleed Screen Cap (1) and O-Ring (3) are secured to the manifold. See Figure 10.
13. Follow Installing the Filter Lid and Clamp Ring exactly (page 6).
Acid Soaking the Filter Cartridges
After an extended period of operation, it may be necessary to soak the filter 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 flow through the FullFloXF® C-Series Cartridge Filter and can impede efficient operation of the equipment.
Muriatic acid is corrosive and can lead to inflammation 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.
REQUIRED TOOLS :
- 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 flow through the filter 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 12.
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 flow nozzle, thoroughly wash down the entire filter cartridge. Wash from the top down, holding the nozzle at a 45-degree angle to the cartridge. See Figure 11, on page 9.
8. Reinstall the cartridges and dispose of the acid solution in accordance with local regulations.
Replacing Filter Cartridges
Filter cartridge life will vary with pool conditions such as bather load, wind, dust, etc. You can expect an average cartridge life of three (3) years under normal conditions.
To replace filter cartridges :
1. Follow Opening the Filter exactly (page 5).
2. Separate the Top Manifold (1) from the filter cartridges and lay the manifold to the side. See Figure 13.
3. Carefully remove each cartridge separately.
4. Place the four replacement cartridges onto the support pipes in the bottom of the tank.
5. Reinstall the Top Manifold onto the cartridges and verify the O-Ring (2) is secured to the manifold. See Figure 13.
6. Follow Installing the Filter Lid and Clamp Ring exactly (page 6).
