Installation Notes
Turn off the pump and relieve system pressure. Open the filter housing, remove the old cartridge, inspect the housing and sealing surfaces. Insert the new C-7450 cartridge, ensuring full seating and correct orientation. Re-assemble the filter, restore flow, and monitor pressure to confirm return to normal operating range.
Maintenance Tip
Rinse the cartridge monthly to maintain performance. If cleaning no longer restores acceptable flow, pleats appear compressed or damaged, or pressure remains elevated, replace the cartridge with the C-7450 to maintain system efficiency and water clarity.
