- Replace when your current filter displays elevated system pressure, flow reduction, frayed pleats or visible damage.

Installation Notes
Turn off pump and relieve system pressure. Drain water from the filter housing if required. Remove the filter tank lid, lift out the old cartridge, inspect the housing and seals for debris or damage. Insert the replacement C-8350 cartridge, align properly, reassemble the housing, restore circulation and verify pressure returns to normal operating range.
Maintenance Tip
Periodically rinse the cartridge during the season. When repeated cleaning no longer restores acceptable pressure or the media shows wear/tears, replace the cartridge to maintain system performance and clear water.
