Installation Notes
Shut off the pump and relieve system pressure if applicable. Open the filter housing, remove the old cartridge element, and clean out debris and sludge. Insert the new C-5601 cartridge, ensuring proper orientation and full seating in the housing. Reassemble the filter, restore circulation, and check the system pressure for normal operating range.
Maintenance Tip
Rinse the cartridge at least monthly to maintain performance. If cleaning no longer restores flow, or pressure remains elevated for longer than usual after cleaning, replace the cartridge with the C-5601 to maintain water clarity and system efficiency.
