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 REFRIGERANT RECOVERY ). If the system cannot reach a vacuum of -93.3 kPa (- 700 mmHg, - 27.55 inHg) in 15 minutes, or cannot hold a vacuum for at least 15 minutes, there is probably a large 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 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

0.99 to 1.10 lbs

15.8 to 17.6 02
Check for refrigerant leaks (see REFRIGERANT LEAK CHECK ).
Check for system performance (see A/C SYSTEM TEST ).
