- Ideal when the existing cartridge shows reduced flow, repeated cleaning is no longer restoring performance, or has collapsed pleats.
- Drop-in replacement for installations specifying part number C-8411.

- Outer diameter: approximately 8-15/16″.
- Length: approximately 17-3/8″.
- Top and bottom end: typically 4″ open.

Installation Notes
Shut off the filter pump and relieve system pressure. Open the filter tank, remove the old cartridge, clean the interior and sealing surfaces. Install the new C-8411 cartridge ensuring full seating and proper orientation, reassemble the filter, restore circulation and monitor pressure to confirm normal operating range.
Maintenance Tip
Rinse cartridges as part of routine service. If cleaning no longer restores flow or you observe high differential pressure, pleat collapse or visible damage to the cartridge, replace with the C-8411 to maintain water clarity and system efficiency.
