• 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.

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

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. Recover the refrigerant in the A/C system (see page


2. Recover the refrigerant in the A/C system (see page 21-80).

3. Evacuate the system until the suction gauge reads approximately - 9 3 . 3 kPa ( - 7 00 mmHg, -27.6 inHg).

Check that the system holds a vacuum for 15 minutes.

• If the A/C system hold vacuum for 15 minutes, the system does not have a leak. Finish the system evacuation (see page 21-80), then go to step 4.

• If the A/C system does not hold vacuum for 15 minutes, the A/C system has a leak. Find and repair the leak (see page 21-82).

4. Add the same amount of new refrigerant oil to the system that was removed during recovery. Use only DENSO ND-OIL 8 refrigerant oil.

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

Select the appropriate units of measure for your refrigerant charging station.

Refrigerant Capacity:

400 to 450 g

0.40 to 0.45 kg

0.9 to 1.0 lbs

14.1 to 15 J oz

6. Check for refrigerant leaks (see page 21-82).

7. Check the system performance (see page 21-89).
