Discharging the System


Only a MVAC-trained, EPA-certified, automotive technician should service the A/C system or its components.

The use of an A/C service center to carry out discharging, evacuation and charging of the refrigerant system is recommended. If an A/C service center is not available, refrigerant system discharging, evacuation and charging may be accomplished using a separate discharging station, vacuum pump, charging meter and manifold gauge set.

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. Prior to recovering, you must verify the purity of the refrigerant. Refer to the operating instructions on the A/C service center for details.
  3. Connect an R-134a refrigerant service center to the low- and high-pressure service gauge port valves following the operating instructions provided by the equipment manufacturer.
  5. Recover the refrigerant from the system following the operating instructions provided by the equipment manufacturer.
  7. Once the refrigerant service center has recovered the refrigerant, switch OFF the power supply.
  9. Allow the system to sit for about 2 minutes, and observe the system vacuum reading. If the vacuum is not lost, disconnect the discharging equipment.
  11. If the system does lose vacuum, repeat the discharging steps until the vacuum level remains stable for 2 minutes.
  13. Carry out the required repairs.
