Usage tips

1. Rotate the valve stem to align the shaft with the valve body so it can pass through smoothly
2. Attach the valve core to the service port and push the shaft toward the port
3. Rotate the shaft until the tip engages the valve core, then turn counterclockwise to secure
4. Pull the shaft completely to close the valve and position the stem perpendicular to flow
5. Loosen the nut, remove the old core, and install a new one

Safety note

• Keep the shaft coupling nut from turning independently to avoid loosening and leaks
• Always ensure the valve is closed before disassembly to prevent refrigerant loss
