- Clean / Replace Cartridge:
  - Turn off the pump.
  - If the filter is located below water level, the valves (or block off suction and discharge lines) should be closed to prevent backflow of water from the pool.
  - Unscrew and remove drain plug to allow water drain from the filter then close drain plug afterwards.
  - Unscrew and remove the locking knob which is in a counterclockwise direction.
  - Carefully remove top cover to have access to filter cartridge.
  - Either pull out the cartridge and clean it or replace it with a clean, spare cartridge.

- Reinstalling Cartridge Element:
  - Take away any collected debris from the bottom of the filter body.
  - Carefully replace the cartridge element over the tie rod and into the filter body.
  - Ensure that the cartridge sits properly on the collector hub in the bottom of the filter body.
  - Hand tight the locking knob in counterclockwise direction.
  - Start the filter.

- Cleaning Cartridge:
  - To remove fine particles, wash it first with a garden hose then dry it before carefully brushing the pleated surface areas since it is easier to clean when dry.
  - Removing algae, suntan oil and body oils can form a coating on the cartridge pleats so the cartridge needs to be soaked first in a solution of filter element cleaner for an hour before reinstalling the filter.
  - The cartridge can look brand new by soaking it in 20% muriatic acid that is added to water in 1 to 1 ratio.
