A/C System Service

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.

2.
Connect a R-134a refrigerant Recover/Recycling/

Charging System to the vehicle, as shown, follow-

ing the equipment manufacturer's instructions.

Insert a thermometer in the center vent outlet.

Determine the relative humidity and air tempera-

ture.
Recovery/Recycling/Charging System

HIGH-PRESSURE

SIDE

LOW-PRESSURE

SIDE

3. Test conditions:

Avoid direct sunlight.

Open hood.

Open front doors.

Set the temperature control dial on MAX COOL,

the mode control switch on VENT and the recir-

culation 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

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.ProCarManuals.com
