A/C Service Tips and Precautions
The air conditioner system uses HFC-134a (R-134a) .efrigerant and polyalkyleneglycol (PAG) retrigerant oil (ND-OIL g: p/N
38899 - PR7 - A0l ), 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 conditioner system or
your servicing equipment will result.
only use 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 svstem.
CAUTION: Exposure lo air conditioner refrigorant and lubricanl vapor or mi3t cln irritato gyos, nose and throat. Avoid
breathing lhe air conditioner refrigerant and lubricant vapor or mist.
lf accidental system discharge occurs, ventilate work area befor€ resuming service.
R-134a service equipment or vehicle air conditioner systems should not be pressure tested or leak tested with compressed
a i r .
@
some mirtures of air and R-l3ifa have been 3hown to be combu3tible at slsvated prossuros and can relult
in fire or explosion causing inlury or property damage. Never use complessod ai. to prgssure t€|st R-134a service equip-
ment or vehicle air conditiongr systems.
Additional health and safety information may be obtained from the refrigerant and lubricant manufacturers.
'1. Always disconnect
the negative cable from the battery whenever replacing air conditioning pans.
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 con necting a ny hose or line, apply a few drops of refrigerant oil (ND-OIL 8: P/N 38899 - PR7 - AO1) to the O-ring.
4. When tightening or loosening a fitting, use a second wrench to support the matching fitting.
5. When recovering the system, use a R-134a refrigerant Recovery/Recycling/Charging
System; don't release refrigerant
into the atmosDhere.
6.
Add refrigerant oil (ND-OlL 8: P/N 38899 - PR7 - A01) 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 refriqer-
ant orls.
.
lmmediately after using the oil, replace the cap on the container and seal ittoavoid moisture absorption,
.
Do not spill the refrigerant oil on the car; it may damage the paint; if the re{rigerant oil contacts the paint, wash it
off immediately.
