Applications & Compatibility
The C-7698 fits 7″ diameter by 29-7/16″ filter housings that use 100 sq ft cartridges. It is commonly found in Hayward Star-Clear Plus C1000 and equivalent cartridge filter systems. This replacement element restores optimal flow and filtration performance, ensuring clean, balanced water with minimal maintenance.
Installation Instructions
- Turn off the pump and relieve system pressure before opening the filter tank.
- Remove the old cartridge and rinse the filter housing thoroughly.
- Inspect the O-ring and tank seal; replace if worn or cracked.
- Insert the new C-7698 cartridge, ensuring it is properly seated in the lower and upper manifolds.
- Reassemble the tank, restart the system, and check for normal operating pressure and flow.
Troubleshooting
- High pressure after cleaning: Verify cartridge pleats are fully expanded and free of trapped debris.
- Low flow or cloudy water: Ensure correct cartridge size and inspect for torn or damaged pleats.
- Leaks around tank lid: Check and lubricate the lid O-ring for proper sealing.
Maintenance Tip
Rinse the cartridge monthly or more often in heavy debris conditions. Deep clean every few months using a cartridge cleaner to dissolve oils and scale buildup. Replace the cartridge annually or if pleats become permanently deformed or discolored. Keeping your C-7698 in good condition ensures your pool water remains clean, clear, and well-balanced year-round.
