2. Open the filter High Flow™ manual air relief valve, (and the waste drain valve, or cap, if your system
has one).
NOTE
Special care must be taken when cleaning cartridge element used in a swimming pool or spa using Baquacil
®
as a sanitizer.
Because of the way Baquacil
®
works, the cartridge element must be cleaned more thoroughly and more frequently than in a
chlorine system. If extreme care is not taken to completely remove all residue from the cartridge element, a buildup will
occur. This buildup will significantly shorten the life of the cartridge element.
Baquacil
®
is a mild coagulant which combines bacterial cells as well as other small particles contributed by the environment,
bathers, etc. into particles large enough to be trapped by the filter. In comparison with all other trapped contaminants in a
typical pool or spa the amount of bacterial cells that are deposited on the filter is minimal. The resulting deposit is a gray
sticky film which can only be removed with Baqua
®
Clean. If TSP or any TSP type cleaner is used prior to stripping the film,
the cleaner and the gray film will combine to form a gum-like substance. Once this occurs, the substance cannot be removed
from the media and the cartridge element must be replaced.
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 locking 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.
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 High Flow™ manual air relief valve drain hose if used.
E. REPLACING CARTRIDGE ELEMENT
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.
1. To replace cartridge element follow steps in section D, Cleaning the Filter.
