System Service
Evacuation
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 lubri-
cant 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
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·
terns.
Additional health and safety information may be obtained
from the refrigerant and lubricant manufacturers.
1. When an NC System has been opened to the atmo-
sphere, such as during installation or repair, it must
be evacuated using a A·134a refrigerant recovery/
recycling/charging station. {If the system has been
open for several days, the receiver/dryer should be
replaced, and the system should be evacuated for
several hoursJ
2, Connect a R·134a refrigerant recovery/recycling/
charging station to the vehicle, as shown, following
the equipment manufacturer's instructions ,
Evacuate the system.
3, If the low·pressure does not reach more than 93.3
kPa (700 mmHg, 27.6 in.Hg) in 15 minutes, there is
probably a leak in the system. Partially charge the
system, and check for leaks (see Leak Test).
