CR-V 2007-2008

Evacuating the System


Specific to:

Honda CR-V 2007-2008

Before beginning this procedure, refer to the Precautions at the beginning of this section. Only a MVAC-trained, EPA-certified, automotive technician should service the A/C system or its components.

Air conditioning refrigerant or lubricant vapor can irritate your eyes, nose, or throat. Be careful when connecting/disconnecting service equipment. Do not breathe refrigerant or vapor.

If accidental system discharge occurs, ventilate work area before resuming service.

Additional health and safety information may be obtained from the refrigerant and lubricant manufacturers.

  1. When an A/C System has been opened to the atmosphere, such as during installation or repair, it must be evacuated using a R-134a refrigerant recover/recycling/charging station.
  3. If the system has been open for several days, the receiver/dryer should be replaced, and the system should be evacuated for several hours.
  5. Connect a R-134a refrigerant recovery/recycling/charging station to the high-pressure service port and the low-pressure service port, following the equipment manufacturer's instruction.
  7. Evacuate the system.
  9. If the low-pressure does not reach more than 27.6 inches Hg (93.3 kPa) in 15 minutes, there is probably a leak in the system. Repair as needed.
