WARNING
Before beginning this procedure, refer to the precautions at the beginning of this section. Use ONLY service equipment that is U.L. listed and certified to meet SAE J2210 requirements for removing HFC-134a (R-134A) from the A/C system.


CAUTION
A/C refrigerant or lubricant is an irritant and can irritate your eyes, nose and/or throat. Be very careful when connecting any service equipment. Do NOT breathe in any refrigerant or vapor. If accidental discharge occurs, thoroughly ventilate the work area before resuming service.

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 Recovery/Recycling/Charging System. (If the system has been open for several days, the receiver/dryer should be replaced, and the system should be evacuated for several hours).

  1. Connect an R-134a refrigerant Recovery/Recycling/Charging System to the high-pressure service port and the low-pressure service port as shown. Make sure to follow the equipment manufacturer's instructions.
