Manually Cleaning the Filter Cartridges
1. Backwash the filter by following Backwashing the Filter on page 9.
2. Follow Opening the Filter (page 5) exactly.
Note: If the filtration system includes a separation tank, close all
other valves and remove the drain plug from the backwash line.
3. Remove hair and lint strainer pot lid from the pump and clean
basket. Replace strainer basket and secure strainer pot lid.
4. Remove the Air Bleed Screen Cap (1) from the Top Manifold (2).
See Figure 9.
5. Clean all debris from the Air Bleed Screen Cap and reinstall onto
the top manifold.
6. Separate the Top Manifold (2) from the filter cartridges and lay the
manifold to the side. See Figure 9.
7. Carefully remove each cartridge separately.
8. Using a garden hose with a straight flow nozzle, wash down the entire filter cartridge. Wash from the top down,
holding the nozzle at a 45-degree angle to the cartridge (see Figure 10). Pay special attention to the area between
pleats.
9. 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
• 1 cup trisodium phosphate (TSP) to 5 gallons of water
• 1 cup dishwasher detergent to 5 gallons of water
b. Rinse the cartridge to remove oils and cleaning solution.
10. 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.
Note: If the filtration system includes a separation tank, reinstall the drain plug into the backwash line.
11. Place the four cartridges back onto the support pipes in the bottom of the tank.
12. Reinstall the Top Manifold (2) onto the cartridges and verify the Air Bleed Screen Cap (1) and O-Ring (3) are
secured to the manifold. See Figure 9.
13. Follow Installing the Filter Lid and Clamp Ring exactly (page 7).

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.
