A/C Service Tips and Precautions
The air conditioning system uses HFC-'134a (R-134a)
refrigerant and polyalkyleneglycol (PAG) refrigerant oil,
which are not compatible with CFC-12 (R-12) refrigerant
and mineral oil. Do not use R-12 refrigerant or mineral
oil in this system, and do not attempt to use R- 12
servicing equipment; damage to the air conditioning
system or your servicing equipment will result.
Use only service equipment that is U.L.-listed and is
certified to meet the requirements of SAE J2210 to
remove R-134a from the air conditioning system.
lf accidental system discharge occurs, ventilate work
area before resuming service.
R-134a service equipment or vehicle air conditioning
systems should not be pressure tested or leak tested
with compressed air.
Additional health and safety information may be
obtained from the refrigerant and lubricant
manufacturers.
. Always disconnect the negative cable from the
battery whenever replacing air conditioning parts.
. Keep moisture and din out of the system. When
disconnecting any lines, plug or cap the fiftings
immediately; don't remove the caps or plugs until
just before you reconnect each line.
. Before connecting any hose or line, apply a few drops
of refrigerant oil to the O-ring.
. When tightening or loosening a fitting, use a second
wrench to support the matching fitting.
. When discharging the system, use a R-134a
refrigerant recovery/recycling/charging station; don,t
release refrigerant into the atmosphere.
. Compressed air mixed with R-134a forms a
combustible vapor.
. T h e v a p o r c a n b u r n o r e x p l o d e c a u s i n g s e r i o u s
inju ry.
. Never use compressed air to pressure test R-134
a service equipment or vehicle air conditioning
systems.
. Air conditioning refrigerant or lubricant vapor
can irritate your eyes, nose. or throat,
. Be carefulwhen connecting service equipment.
. Do not breathe refrigerant or vapor.

Add the recommended refrigerant oil in the amount
listed if you replace any of the following parts.
. To avoid contamination, do not return the oil to the
container once dispensed, and never mix it with other
refrigerant oils.
. lmmediately after using the oil, reinstallthe cap on
the container, and seal it to avoid moisture
aosorpton.
. Do not spill the refrigerant oil on the vehicle; it may
damage the paint. lf it gets on the paint, wash it off
immediately.
