A/G System Service
Performance Test
The performance test will helD 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 svstem.
CAUTION: Exposure to air condiiioner r€trigerant and
lubricant vapor or mist can irritate €yes, nose and
throat. Avoid bre8thing the air conditioner retrige.ant
and lubricant vapor or mist,
lf accidental system discharge occurs. ventilate work
area before resuming service.
R-134a service equipment o. vehicle air conditioner sys-
tems should not be pressure tested or leak tested with
comDressed air.
@ some mixtur€s ol air and R-134a have becn
shown to be combuslible at olsvated pressures and can
result in lire or explosion causing iniury or property
damage. Never use compressed air to prgssure test R-
13i[a service equipment or vehicle air conditioner sys.
tems.
Additional health and safety information may be obtained
from the refrigerant and lubricant manufacturers.
Recovory/Recycling/charging station
LOW.PRESSURESIDE
1.Connect a R-134a refrigerant recover/recycling/
charging station to the vehicle, as shown. following
the equipment manufacturer's instructions,
Insen a thermometer in the center air vent. Determine
the relative humidity and air temperature.
Test conditions:
. Avoid direct sunlight.
o Open hood.
. open front doors.
. Set the temperature control dial on MAX COOL,
the mode control dial on VENT and the reci.cula-
tion control switch on RECIRCULATE.
. Turn the A,/C switch on and the fan switch on
MAX.
. Run the engine at 1,500 rpm.
. No driver or passengers in vehicle
After running the air conditioning for 10 minutes
under the above test conditions, read the deliverv
temperature from the thermometer in the dash vent
and the high and low system pressure from the Ay'Cgauges.
