Installation Notes

Installation is performed by a licensed HVAC technician or plumber. De-pressurize and evacuate the line completely before removing or installing any flare fitting to prevent injury or refrigerant release. Flare connections require proper flaring tools to ensure leak-free joints — inspect flare seats before assembly. Follow applicable local codes and manufacturer torque guidance for flare fittings.
