Filter Cartridge Cleaning
Instructions
General
Chlorine Users
- Remove the filter cartridge from the housing as per
manufacturer’s instructions.
- Pressure wash with a garden hose with a straight flow
nozzle.
- Allow the filter cartridge to dry to remove the fine
particles.
- Remove the fine particles by gently dusting the filter.
- Algae, perspiration, suntan oil, and other oils present in
filter can be removed by soaking the cartridge in a solution of commercially available
filter cleaners.
- Excessive calcium carbonate or other mineral deposits on the
filter can be removed by treating it with a muriatic acid solution.
- Rinse the cartridge clean and re-install it in the housing.
Baquacil Users
It is important to follow manufacturer’s guidelines
and warnings when using Baquacil , Baqua Shock , and Baqua Clean.
Special precautions must be taken when cleaning filter
cartridges used in a spa or swimming pool using Baquacil as a sanitizer. The filter
cartridge must be cleaned more often and thoroughly when using Baquacil.
Chlorine oxidizes the bacteria in the water whereas active
ingredient in Baquacil -- polyhexamethylene biqunaide (PHMB) destroys the bacterial cells.
The active ingredient PHMB locates and binds to bacterial surfaces and attacks the outer
bacterial wall. After penetrating the outer wall, the inner cell membrane is destroyed.
This destruction allows the cell contents to disperse into their surroundings. They are
further broken down into their elemental parts by non-chlorine oxidizer Baquacil Shock.
Baquacil is a mild coagulant which combines bacterial cells
and other particles in the environment into particles large enough to be caught by the
filter. The resulting deposit is a gray sticky film on media, which can only be removed
with Baqua Clean.
If trisodium phosphate (TSP) or any TSP 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 filter
cartridge must be replaced.
