A/C Service Tips and Precautions
The air conditioner system uses HFC-134a (R-134a) refrigerant and polyalkyleneglycol {PAG) refrigerant oil (ND-OlL 8: P/N
38897-PR7-A01AH or 38899 - PR7 - A01), 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.
Use only service equipment that is U.L.-listed and is certified to meet the requirements of SAE J2210 to remove R-l34a
from the air conditioner system.
CAUTION: Exposure to air conditioner refrigerant and lubricant vapor ot mist can irritate eyos, nose.nd throat, Avoid
breathing th€ air conditionsr rofrigerant 8nd lubricant vapo. 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 leak tested with comp.essed
atf,
@ some mixtures ol air and R-13i[a have been shown to be combustible at olevat6d pre3sures and cln resuh
in fire or explosion causing iniury or property damage. Nover uso compressed air to prossure te3t R-13,[8 service equip-
ment or vehicle air condition6r 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 parts.
2. Keep moisture and dust out of the system. When disconnecting any lines. plug or cap the Jittings 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 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 atmosphere.
6. Add refrigerant oil after replacing the following parts.
NOTE:
. To avoid contamination, do not return the oil tothe container once dispensed, and never mix itwith other refriger-
ant oils.
.lmmediatelyafterusingtheoil,replacethecaponthecontainerandseal it to avoid moisture absorption.
. Do notspillthe refrigerant oil onthevehicle; it maydamagethe painu itthe refrigerant oil contacts the paint, wash
it off immediately.

A/C System Service
Recovery
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 irritale eyes. nose and
throat. Avoid breathing the air conditioner rclrigerant
and lubricant vapor o. mist.
lf accidental system discharge occurs, ventilate work
area before resuming service.
R-134a service equipment or vehicle air conditioner sys-
tems should not be Dressure tested or leak tested with
compressed air.
@ some mixtures of air and R-134a have
been shown to be combustible at €levated pros3ures
and can result in lire or explosion causing iniury or
plop€rty damage. Never use comprossgd air to pressure
iest R-134a service equipment or vehicle air conditioner
sYstsms.
Additional health and safety information may be
obtained from the refrigerant and lubricant manufac-
tures,
Connect a R-134a refrigerant Recovery/Recycling/
Charging System to the vehicle. as shown, follow-
ing the equipment manufacturer's instructions.
Measure the amount of refrigerant oil removed
from the IVC system after the recovery process is
completed.
NOTE: Be sure to install the same amount of new
refrigerant oil back into the A/C system before
charging.

This compressor is a Nippondenso piston type compressor for HFC-134a (R-134a). A revolving inclined disc drives the sur-rounding 10 reciprocating pistons. As the inclined disc revolves, it pushes the pistons, ,protected by a ceramic shoe, thuscompressing the refrigerant.
