Installation & Usage Notes
Before servicing, shut off the pump and relieve system pressure. Remove the existing cartridge element, inspect the filter tank and manifold for debris.

If the pressure gauge rises significantly sooner than expected, clean or replace the cartridge ahead of schedule.

- Inspect for pleat collapse, media wear or end-cap damage—replace if any is found to protect the filtration system’s performance.
