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 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 large 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 the leak (see REFRIGERANT LEAK CHECK ).
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:

450 to 500 g

0.45 to 0.50 kg

1.0 to 1.1 lbs

15.8 to 17.6 oz
Check for refrigerant leaks (see REFRIGERANT LEAK CHECK ).
Check the system performance (see PERFORMANCE TEST ).
