System Charging
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.
- Additional health and safety information may be obtained from the refrigerant and lubricant manufacturers.
- 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.
- Recover the refrigerant in the A/C system.
- Evacuate the system. If the system cannot reach a vacuum of -93.3 kPa (-700 mmHg,-27.6 inHg) in 15 minutes, or cannot hold a vacuum for at least 15 minutes, these is probably a leak. Do the refrigerant leak check, and repair any leaks before charging the system.
- Add the same amount of new refrigerant oil to the system that was removed during recovery. Use only DENSO ND-OIL 8 refrigerant oil.
- 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:
700 to 750 g
0.70 to 0.75 kg
1.5 to 1.7 lbs
24.7 to 26.5 oz
- Check for refrigerant leaks (see REFRIGERANT LEAK TEST ).
- Check for system performance (see A/C SYSTEM TEST ).
