Cleaning the Filter
1. Turn the pump off, shut off any automatic controls to ensure that the system is not inadvertently started during
servicing.
2. Open the filter High Flow™ manual air relief valve (and the waste drain valve, or cap, if your system has one).
3. Remove hair and lint strainer pot lid and clean basket. Replace basket and secure lid.
4. Disconnect air relief drain hose if installed.
5. Remove lock ring by depressing safety latches on both sides of ring and rotate counterclockwise, then remove
tank lid.
6. Remove the element assembly by placing hands in lifting handles and pulling straight up on the element
assembly.
7. Remove the cartridge element from the center support tube.
8. Using a garden hose with a nozzle, direct water spray at the cartridge element to dislodge and wash away
accumulated foreign matter. Water may be sprayed at the outside as well as the inside of the cartridge
element for thorough cleaning.
7. 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
• 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.
8. Direct the water spray to wash out the inside of the tank body and bottom manifold. Water and debris will drain
out through the open drain plug.
9. Check gasket around outer lip of bottom plate. Gasket must be firmly and evenly set around the entirety of the
outer lip.
9. Turn the cartridge element over several times during the washing operation to clean the media thoroughly.
10. Clean and remove debris from inside the filter tank and from the O-ring and O-ring groove on the tank body.
11. Replace clean cartridge element on support tube and install assembly into the filter tank body, aligning the
arrow on the support tube with the inlet port of the filter, making sure it is fully seated. Make sure the internal
air relief screen is attached to the top of the element support tube.
12. Replace the tank lid onto the tank body making sure it is fully and firmly seated on the tank body.
13. Place lock ring over tank lid, and centering the lock ring on the threads of the tank body, turn the lock ring
clockwise until the safety latches click and the lock ring hits the stops on the body. DO NOT ATTEMPT TO
OVER-TIGHTEN THE LOCK RING AFTER LOCK RING HAS HIT THE STOPS ON THE BODY.
Note
: Any time the filter tank is opened, and/or element assembly is removed, be sure to generously
coat the O-ring with silicone lubricant before reassembling the unit. DO NOT USE PETROLEUM BASED
LUBRICANTS BECAUSE THEY HAVE A DETERIORATING EFFECT ON RUBBER.
14. Replace drain cap and reinstall manual air relief valve drain hose if used.

Cartridge element life will vary with pool conditions such as bather load, wind, dust, etc. You can expect an
average media life of three (3) years under normal conditions.

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 filter system.
Heed all manufacturers' instructions and warnings when using polyhexamethylene biguanide sanitizers or other
cartridge filter cleaner solutions.
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.
