Leak Testing

Print


CAUTION
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.


NOTE
This procedure requires the use of Leak detector, Honda Tool and Equipment YGK-H-10PM commercially available, or equivalent leak detector.


CAUTION
Compressed air mixed with R-134a forms a combustible vapor. The vapor can burn or explode causing serious injury. Never use compressed air to pressure test R-134a service equipment or vehicle air conditioning system.


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.

Use only service equipment that is U.L.-listed and is certified to meet the requirements of SAE J2210 to remove HFC-134a (R-134a) from the air conditioning system.


CAUTION
If accidental system discharge occurs, ventilate work area before resuming service.


WARNING
R-134a service equipment or vehicle air conditioning systems should not be pressure tested or leak tested with compressed air.

Additional health and safety information may be obtained from the refrigerant and lubricant manufacturers.

  1. 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.
