7. Maintenance
Regular maintenance of your POOLPURE PFT-AF100 filter tank is crucial for maintaining crystal-clear water and extending the life of your system. The filter is equipped with a 15um high-efficiency filter element and high-density pleated fiber, which requires periodic cleaning or replacement.
7.1. When to Clean or Replace the Filter Element
Monitor the pressure gauge. When the pressure rises 8-10 PSI above the initial clean filter pressure, or if you notice a decrease in water flow, it's time to clean or replace the filter element.
7.2. Cleaning the Filter Element
- Turn off Pump: Always turn off the pool pump and relieve any pressure in the system before opening the filter.
- Unscrew Lock Ring: Carefully unscrew the large lock ring at the top of the filter tank.
- Remove Lid: Remove the filter tank lid.
- Remove Filter Element: Gently lift and remove the dirty filter element from the tank.
- Rinse Element: Use a garden hose with a spray nozzle to thoroughly rinse the pleats of the filter element. Work from top to bottom, ensuring all debris is removed. For stubborn dirt or oils, a specialized filter cleaning solution may be used according to its instructions.
- Reinstall Element: Once clean, place the filter element back into the tank, ensuring the center pipe is properly installed and the element is seated correctly.
- Replace Lid and Lock Ring: Replace the lid and screw down the lock ring firmly. DO NOT OVERTIGHTEN.
- Restart Pump: Turn on the pool pump and check the pressure gauge. The pressure should return to near the initial clean filter reading.
