Installation & Compatibility Notes
Before installing, turn off the pump and relieve all system pressure. Remove the filter tank lid, remove the old cartridge element, and clean the tank interior of debris. Insert the CX225RE cartridge ensuring it is seated properly, re-mount the lid and restore circulation. Monitor pressure after startup to confirm return to baseline.
Maintenance Tips
- Track the clean-start pressure and note when pressure increases by 8-10 psi above baseline — at that point inspect/clean or replace the cartridge as needed.
- Rinse the cartridge media during maintenance intervals to extend life and maintain flow.
- Replace the cartridge when media is torn, collapsed, or when rinsing no longer restores proper pressure drop.
