A/C Service Tips and Precautions
E I
The air conditioner system uses HFC-134a (R-134a) refrigerant and polyalkyleneglycol (PAG) refrigerant oil*' which are not
compatible with 6p6-12 1n-tZ) 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 conditioner system or your servicing equipment will result.

P/N 38897 - Pl3 - A01AH: 120 mf (4 fl'oz. 4.2 lmp'oz)
. P/N 38899 - P13 - A01: 40 ml 11 lBIl'oz, 1.4 lmp'oz)
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 conditioner system.
CAUTION: Exposure to air conditioner r€ftigerant and lublicant vapor or mist can irritatg eyes, nose and lhroat. Avoid
breathing the air conditioner refrigerant and lubticant vapor or mist.
lf accidental system discharge occurs, ventilate work area before resuming service'
R-134a service equipment or vehicle air conditioner systems should not be pressure tested or Ieak tested with compressed
a i r .
@
Some mixtures ol air and R.i34a havs been shown to b9 combusiible at elevated pressures and can resuh
iiTiiffiiplo"ion
causing iniury or property damage. Nevet use compresscd air to pressure test R-13/+a servica equip-
ment or vehicle air conditionor systems.
Additional health and safetY information may be obtained from the refrigerant and lubricant manufacturers'
t.
Always disconnect the negative cable from the battery whenever replacing air conditioning parts.
2.
Keep moisture and dust out of the system. When disconnecting any lines, plug or cap the fittings immediately; don't
remove the caps or plugs until just before you reconnect each line.
3.
Before connecting any hose or line, apply a few drops of refrigerant oilto the O-ring'
4. When tightening or loosening a titting, use a second wrench to support the matching fitting'
5. When discharging the system, use a R-134a refrigerant Recovery/Recycling/charging
system; don't release refriger-
ant into the atmosphere
6.
Add refrigerant oil after replacing the following parts:
NOTE:
. To avoid contamination, do not return the oil to the container once dispensed, and never mix it with other refriger-
ant oils.
. lmmediately after using the oil, replace the cap on the container, and seal it to avoid moisture absorption
. Do not spillthe refrigerant oil on the vehicle; it may damage the paint; ifthe refrigerant oil contacts the paint, wash
it off immediatelY.

.., For compressot teplacement, subtract the volume of oil drained {rom the

NOTE: Even if no oil is drained from the removed compressor, don t draln more
