R-134a service equipment or vehicle air conditioner sys-

some mixtures ot air and R-t3ita have
been shown to be combustible at elevated pressures
and can result in fire of explosion causing injury or
property damage. Never use compressed air to pressure
test R-134a service equipment or vehicle air conditionet
svstems.
Additional health and safety information may be obtained
from the refrigerant and lubricant manufacturers.
When an A"/C Svstem has been ooened to the atmo-
sphere, such as during installation or repair, it must
be evacuated using a R-134a refrigerant Recovery/
Recycling/Charging

open for several days, the receiver/dryer should be
replaced, and the system should be evacuated for
several hours.)
Connect a R-134a refrigerant Recovery/Recycling/
Charging System to the vehicle, as shown, follow-
ing the equipment manufacturer's instructions.
NOTE: lf low pressure does not reach more than
9 3 . 3 k P a ( 7 0 0 m m H 9 , 2 7 . 6 i n . H g ) i n 1 5 m i n u r e s ,
