Evacuating the System

Print

Using An R-134a Manifold Gauge Set




CAUTION
Refer to the applicable precautions for this system before performing the following operation. Failure to follow the warnings and cautions could result in possible personal injury or death.


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 meter and manifold gauge set.


NOTE
Leaks in refrigerant system service equipment, hoses or gauges can cause a leak in vacuum that may be misinterpreted as a problem with the vehicle's refrigerant system. It is necessary to leak-test all refrigerant system service equipment, hoses and gauges on a weekly basis to verify that no leaks are present.

  1. Connect the R-134a manifold gauge set to the low-side and high-side service gauge port valves.
  2.  
  3. Connect the center (yellow) hose from the manifold gauge set to the suction port on the vacuum pump.
  4.  
  5. Open all valves on the R-134a manifold gauge set and both service gauge port valves.
  6.  
  7. Turn on the vacuum pump and evacuate the system until the low-pressure gauge reads at least 29.5 in. Hg. (99.4 kPa) of vacuum and as close to 30 in. Hg (101.1 kPa) as possible. Continue to operate the vacuum pump for a minimum of 45 minutes.
  8.  
  9. Close the high-side and low-side valves on the manifold gauge set (not the service gauge port valves) and turn off the vacuum pump.
  10.  
  11. Observe the low-pressure gauge for 5 minutes to make sure that the system vacuum is held. If vacuum is not held for 5 minutes, leak test the system, repair the leak and evacuate the system again.
