Installation Notes and Tips

Verify refrigerant type, port sizes, and mounting layout before installation. This valve uses female insert O-ring fittings and a block-style body, so the mating surfaces should be clean and the correct O-rings should be used during service. Confirm the system is properly evacuated and recharged after replacement, and inspect the surrounding A/C components for contamination or wear that could affect the new valve.
