)
- Close the high and low-pressure valve of the gauge manifold.
- Connect the charging hose (blue) to the low-pressure valve and connect the charging hose (red) to the high-pressure valve of the gauge manifold.
- Install the quick joint (for low-pressure) to the charging hose (blue), and connect the quick joint (for high-pressure) to the charging hose (red).
CAUTION- To connect the quick joint, press section A firmly against the service valve until a click is heard.
- When connecting, run your hand along the hose while pressing to ensure that there are no bends in the hose.
NOTE: The high-pressure service valve is on the A/C pipe and the low-pressure service valve is on the suction hose.
- Connect the quick joint (for low-pressure) to the low-pressure service valve and connect the quick joint (for high-pressure) to the high-pressure service valve.
- Start the engine.
- Set the A/C controls as follows:
- A/C switch: A/C - ON position
