Refer to the applicable precautions for this system before performing the following operation. Failure to follow the warnings and cautions could result in possible personal injury or death.
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.
If accidental system discharge occurs, ventilate work area before resuming service.
When an A/C System has been opened to the atmosphere, such as during installation or repair, it must be evacuated using a R-134a refrigerant recovery/recycling/charging station (If the system has been open for several days, the receiver/dryer should be replaced, and the system should be evacuated for several hours.)
Connect a 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
NOTEIf the low-pressure does not reach more than 27.6 in.Hg (93.3 kPa, 700mm Hg) in 15 minutes, there is probably a leak in the system. Partially charge the system, and check for leaks.
