Installation Instructions
- Turn off the pump and relieve system pressure before opening the filter tank.
- Remove the old cartridge, inspect the tank for debris and confirm gasket or O-ring condition.
- Place the new CX1750RE cartridge into the tank, ensuring proper alignment and seating.
- Reinstall the lid/clamp, restore circulation and check pressure gauge for normal operating values.
Troubleshooting
-
High filter pressure after installation: Check for closed return/valve restrictions, verify correct cartridge size and ensure the lid is properly sealed.
-
Low flow or cloudy water: Confirm the cartridge is correctly seated, pleats are not collapsed and the filter housing is not leaking or bypassing unfiltered water.
-
Cartridge won’t fit or is too small: Double-check your filter model and old cartridge dimensions—ensure you’re replacing with the appropriate size and part number.
Maintenance Tip
Regularly rinse the cartridge to remove surface debris and conduct a deeper clean with a dedicated cartridge cleaner at least once per season. Replace the cartridge when pleats are damaged, flattened or if system pressure remains elevated after cleaning. Proper care of the CX1750RE helps maintain clear water and efficient pump operation.
