Installation Notes
Turn off the pump and relieve system pressure. Drain or backwash the filter as needed. Remove the old elbow assembly and inspect the filter tank flange, gasket surface, and threads. Confirm all sealing surfaces are clean. Install the new ECX4220A assembly, ensure proper torque on flange bolts, prime and restart the system. Check for proper flow and no leaks.
Maintenance Tip
Inspect the elbow assembly and check-valve annually during service. Replace if you observe cracks, leaks, difficulty in valve operation, or signs of back-flow to maintain optimal filter performance and longevity.
