Installation & Compatibility Notes

Before installation, shut down the filtration pump and relieve pressure in the tank. Remove the old bulkhead fitting and clean all seal surfaces. Insert the new CX3035F fitting, ensure O-ring or gasket is properly seated, secure lock-nut or flange from the inside of the tank, and attach the plumbing side with appropriate sealant or slip connection. After assembly, refill and re-prime the system and inspect for leaks around the bulkhead.

Maintenance Tips

Inspect the bulkhead fitting annually for signs of leakage, cracking or movement.
If pressure rises excessively or bypass flow is observed, check the bulkhead fitting’s seal and torque.
Keep spare bulkhead fittings and O-rings in your service inventory to reduce downtime during maintenance or rebuild jobs.
