A/G System Service
Performance Test
The performance test will help determine if the air con-
ditioner system is operating within specitications.
Only use 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 relrig€rant and
lubricant vapor ot mist can irritate eyes, nose and
throat. Avoid breathing the air conditioner rstrigerant
and lubricant vapor or mi3t.
It 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 atr.

t€st R-134a ssrvice equipment or vohicl€ air conditioner
syst€ms.
Additional health and safety information may be
obtained from the refrigerant and lubricant manufactur-
ers.
1. Connect a R-134a refrigerant Recovery/Recycling/
Charging System to the car, as shown, iollowing
the equipment manufacturer's instructions.
2. Insert a thermometer in the center vent outlet.
Determine the relative humidity and air temperature
by calling the local weather information line,
3. Test conditions:
. Avoid direct sunlight.
. Open hood.
. Open front doors
. Set the temperature control lever to MAX COOL,
the mode control switch on VENT and the recir-
culation control switch on RECIRCULATE.
. Slide the heater fan switch on MAX
. Run the engine at 1,500 rPm
. No driver or passengers in vehicle.
4. After running the air conditioning for 10 minutes
under the above test conditions. read the delivery
temperature from the thermometer in the dash vent
and the high and low system pressure from the A,/C
gauges.
