NOTE: Ford Motor Company recommends use of an A/C service center to carry out recovery, evacuation, and charging of the refrigerant system. If an A/C service center is not available, refrigerant system recovery, evacuation, and charging may be accomplished using a separate recovery station, vacuum pump, charging cylinder, and manifold gauge set.
Prior to recovering the refrigerant system, you must verify the purity of the refrigerant.
Connect an R-134a A/C service center to the low- and high-pressure service gauge port valves.
NOTE: Some R-134a service centers require the use of an A/C manifold gauge set.
Recover the refrigerant from the system following the operating instructions provided by the equipment manufacturer.
Once the service center has recovered the vehicle A/C system refrigerant, close the service center inlet valve (if equipped). Then switch off the power supply.
Allow the vehicle A/C system to remain closed for about two minutes . Observe the system vacuum level as shown on the gauge. If the vacuum does not decrease, disconnect the refrigerant center hose(s).
If the system vacuum does decrease, repeat Steps 2 through 5 until the vacuum level remains stable for two minutes .
