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 (see REFRIGERANT RECOVERY ).
- Evacuate the system until the suction gauge reads approximately -93.3 kPa (-700 mmHg, -27.6 in.Hg). 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 SYSTEM EVACUATION ), 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 leak (see REFRIGERANT LEAK CHECK ).
- 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:
550 to 600 g
0.55 to 0.60 kg
1.2 to 1.3 lbs
19.4 to 21.2 oz
- Check for refrigerant leaks (see REFRIGERANT LEAK CHECK ).
- Check the system performance (see A/C SYSTEM TEST ).
