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. Insert the new C-2302 cartridge ensuring it seats properly in the manifold or base plate. Re-assemble the filter lid, restore circulation and monitor pressure. 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.
