Installation Notes
Turn off the pump and relieve system pressure. Open the filter housing, remove the old cartridge, clean the interior surfaces, inspect seals and housing, insert the new C-5374 cartridge ensuring full seating and correct orientation, close the tank, restore circulation and monitor pressure to confirm normal operating range.
Maintenance Tip
Rinse the cartridge monthly to maintain performance. If cleaning no longer restores acceptable flow, pleats appear collapsed or broken, or pressure remains elevated for extended time, replace the cartridge with the C-5374 to maintain water clarity and system efficiency.
