Evacuation and Charging

SYSTEM CHARGING SET-UP
Ford Motor Company recommends using a charging station to perform evacuation and charging of the refrigerant system. Follow the instructions provided with the charging station.

If a charging station is not available, system charging may be accomplished using a separate vacuum pump, charging cylinder and manifold gauge set.

If the charging cylinder method is used, the center port of the manifold gauge set should have two refrigerant hoses with integral shut-off valves built into the manifold gauge set. If the gauge set is the type that does not have shut-off valves and two hoses at the center port, a tee fitting and two hoses should be installed at the center port. In addition, the hoses attached to the center port should have shut-off valves at the other ends of the two center hoses to prevent air from entering the hoses when not connected to the vacuum pump and charging cylinder.

CHARGING WITH A CHARGING CYLINDER
1. Connect the manifold gauge set.
2. Discharge the refrigerant system.
3. Evacuate the refrigerant system.
4. Connect the center hose of the manifold gauge set to a refrigerant cylinder. If a charging station is used, follow the instructions of the manufacturer.

NOTE: Keep the refrigerant cylinder in the upright position.

5. Open the high-pressure valve on the manifold gauge set to allow refrigerant to enter the system. Continue to add refrigerant until approximately 400 grams (14.12 oz) is drawn into the system.
6. Close the high-pressure valve.
7. Start the engine and turn on the air-conditioning.

CAUTION: Do not open the high-pressure valve while the engine is running.

8. Open the low-pressure valve on the manifold gauge set to allow refrigerant to enter the system. Continue to add refrigerant until approximately 400 grams (14.12 oz) is drawn into the system.
9. Close the low-pressure valve.
10. Check the air-conditioning system for proper operation.
11. Stop the engine.
12. Disconnect the manifold gauge set.
