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 (see SYSTEM EVACUATION ). If the system cannot reach a vacuum of -93.3 kPa (700 mmHg, 27.6 in.Hg) in 15 minutes, or cannot hold a vacuum for at least 15 minutes, there is probably a leak. Do the refrigerant leak check (see 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 SP-10 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:
400 to 450 g
0.40 to 0.45 kg
0.9 to 1.0 lbs
14.1 to 15.9 oz
- Check for refrigerant leaks (see REFRIGERANT LEAK CHECK ).
- Check the system performance (see A/C SYSTEM TEST ).
