Performance Test

The performance test will help determine if the air con-
ditioner system is operating within specifications.
Use only service equipment that is U.L.-listed and is cer-
tified to meet the requirements of SAE J2210 to remove
HFC-134a (R-134a) from the air conditioner system.
CAUTION: Exposure to air conditioner refrigerant and
lubricant vapor or mist can irritate eyes, nose and
throat. Avoid breathing the air conditioner refrigerant
and lubricant vapor or mist.
If accidental system discharge occurs, ventilate work
area before resuming service.
R-134a service equipment or vehicle air conditioner sys-
tems should not be pressure tested or leak tested with
compressed air.
Some mixtures of air and R-134a have been
shown to be combustible at elevated pressures and can
result in fire or explosion causing injury or property
damage. Never use compressed air to pressure test R-
134a service equipment or vehicle air conditioner sys-
tems.
Additional health and safety information may be obtained
from the refrigerant and lubricant manufacturers.
1. Connect a R-134a refrigerant recover/recycling/
charging station to the vehicle, as shown, following
the equipment manufacturer's instructions.
2. Insert a thermometer in the center air vent. Deter-
mine the relative humidity and air temperature.
3. Test conditions:
