OPERATING INSTRUCTIONS
Select the correct tool configuration for the job:
Select the correct adapter. There are two different adapters, 13mm (Blue) and 16mm (Red)
VALVE CORE REMOVAL
1. Connect the correct adapter to the Valve Body. Make sure all connections are tight. Failure to do this can
cause refrigerant leakage.
2. Open the Valve Knob on the Valve Body, so the Shaft can pass through the Valve Body.
3. Connect the Adapter to the service port of the A/C system.
4. Push the Shaft toward the service port. Slowly and carefully rotate the Shaft until the tip of the Shaft engages
the body of the valve core.
5. Rotate the Shaft counterclockwise turning the Knob of the Shaft.
Make sure the Shaft Nut does not turn as you are turning the Shaft. This can cause the Shaft Nut to loosen and
refrigerant to leak out.
6. Continue rotating the Shaft until the valve core is backed out fully (Do Not Force!!!)
NOTE
If the valve core is correctly removed, the Shaft will travel outward due to the pressure of the system. If it does
not push outward, either the system is empty or the valve core was not fully removed.
7. Once the Shaft is pulled out all the way, close the valve.
8. Loosen and remove the Shaft Connection Nut from the Valve Body.
9. Remove the defective valve core.
VALVE CORE INSTALLATION
1. Insert the new valve core into the tip of the Shaft and insert the assembly into the Valve Body.
2. Tighten the Shaft Connection Nut to the Valve Body.
3. Open the Valve Knob.
4. Push the shaft inward and turn clockwise to insert the valve core, continue turning until valve core is fully
installed.
5. Once the new valve core is fully installed, pull the Shaft out and turn the Valve knob to the closed position
6. Slowly open the Valve Knob to relieve the pressure from the tool. If refrigerant continues to leak out, the
valve core is not correctly installed. Close the Valve and try again.
7. Once the valve core is correctly installed, remove the Adapter and the Valve Body from the system.
