VALVE CORE REMOVAL
1. Turn Valve Lever in the direction of flow so the shaft can go through the body.
2. Connect the valve core to the service port of the system.
3. Push the shaft towards the service port. Slowly and carefully rotate the shaft until the tip of the shaft engages the body of the valve core.
4. Rotate the shaft counter-clockwise by turning the shaft knob.
WARNING: MAKE SURE THE SHAFT CONNECTION NUT DOES NOT START TO TURN AS YOU ARE TURNING THE SHAFT. THIS COULD CAUSE THE SHAFT CONNECTION NUT TO LOOSEN AND REFRIGERANT WOULD LEAK OUT!
5. Continue rotating the shaft knob until you cannot turn the shaft anymore. DO NOT FORCE!
6. With the shaft pulled out all the way, CLOSE THE VALVE. (Valve Lever perpendicular to the direction of FLOW)
WARNING: FAILURE TO CLOSE VALVE COULD CAUSE INJURY AND WOULD RESULT IN A LOSS OF REFRIGERANT!
7. Loosen and remove the shaft connection nut from the valve body.
8. Remove the damaged valve core.
