Applications & Fitment
This closure plate is specifically designed for use in Hayward SwimClear® cartridge filter tanks where the original factory plate is damaged, warped or leaking. Replacing it restores proper internal flow paths and prevents misalignment or bypass of unfiltered water.
Installation Instructions
- Shut off system power and relieve filter pressure before opening the filter.
- Remove the filter lid, lift out the cartridge elements and unscrew the old top plate.
- Install the CX5020DA plate, properly seat the cartridge elements, secure bolts in a cross-pattern and reassemble the tank.
- Restore system pressure, inspect for leaks and confirm proper filter operation.
Troubleshooting & Maintenance Tip
-
Leak between lid and tank: Ensure bolts are evenly torqued, plate sits flat and gasket (if applicable) is in good condition.
-
Reduced flow or high differential pressure: Verify cartridges are seated correctly on the new plate and the plate’s ports are unobstructed.
-
Plate distortion: Replace immediately if the plate shows signs of warping, cracking or chemical degradation.
Replace the CX5020DA whenever filter service reveals a damaged or compromised top closure plate. Maintaining this part in good condition helps ensure the longevity and performance of the SwimClear® cartridge filter system.
