Installation & Compatibility Notes

Before installation, shut off the pump and relieve system pressure. Remove the clamp assembly, lift off the old top plate, and inspect the cartridge elements and seating surface for debris or damage.

After startup, monitor pressure and flow to confirm system integrity.

Maintenance Tips

Inspect the top plate at each service interval for cracks, warping or seal irregularities.
If you notice bypass flow, rising pressure or misalignment of cartridge elements, replacing the top plate is a recommended corrective step.
Ensure that the clamp assembly is properly torqued and the O-ring is intact to maintain full seal effectiveness.
