Installation Notes

Installation is typically performed by licensed plumbers or HVAC technicians following applicable IPC and local mechanical code requirements. Before installing or removing any fitting, depressurize and isolate the line completely. Ensure tubing is cut cleanly and squarely, and that the tube end is free of burrs before insertion into the push-to-connect port. Verify thread engagement is complete and the O-ring is properly seated before returning the system to service.
