CAUTION
- Air conditioning refrigerant or lubricant vapor can irritate your eyes, nose, or throat.

- Be careful when connecting service equipment.

- Do not breathe refrigerant or vapor.


NOTE:

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

1. Connect an R-134a refrigerant recovery/recycling/charging station (A) to the high-pressure service port (B) and the low-pressure service port (C), as shown, following the equipment manufacturer's instructions.

2. Evacuate the system. A/C System Evacuation

3. Add the same amount of new refrigerant oil to the system that was removed during recovery. Use only SP-10 refrigerant oil.

4. Charge the system with the specified amount of R-134a refrigerant. Do not overcharge the system; the A/C compressor will be damaged.
