Unicel Cartridge Cleaning Instructions

When should a cartridge element be cleaned?

For swimming pools, clean the cartridge when filter canister pressure reaches 8 PSI above the initial system or new cartridge starting pressure. For spas, establish a routine cartridge cleaning schedule based on the amount of spa usage (this should include rinsing the cartridge weekly, as well as using Filter Cleanse every 4-6 weeks)..

What is the procedure to clean my cartridge?

  • 1.

    Remove the cartridge from the filter housing following the manufacturer’s instructions.

  • 2.

    Use a garden hose with a straight flow nozzle to wash down the filter element. Work from the top down, holding the nozzle at a 45o angle, and wash all the pleats with emphasis between pleats.

  • 3.

    Rinse until all dirt and debris is gone.

  • 4.

    For all spa cartridges and elements used in swimming pools and spas where perspiration, suntan lotions, and other oils are present, soak the element for at least six hours (overnight is most effective) in a commercial filter cleaner (Filter Cleaner).

  • 5.

    For hot tub filters: Add 500ml of Filter Cleanse to at least 20L of water. Ensure that the entire filter is submersed in the solution and soak overnight.

  • 6.

    Rinse the cartridge again to remove oils and cleaning solution.

  • 7.

    Let the cartridge air dry completely before installing it back into the filter housing.
