General Description
HVAC SYSTEM (HEATER, VENTILATOR AND A/C)
C: CAUTION
1. HFC-134A A/C SYSTEM
•The cooling system components for the HFC-
134a system such as the refrigerant and compres-
sor oil are different from the conventional CFC-12
system components and they are incompatible with
each other.
•Vehicles with the HFC-134a system can be iden-
tified by the label (A) attached to the vehicle.
Before maintenance, check which A/C system is in-
stalled to the vehicle.
2. COMPRESSOR OIL
•HFC-134a compressor oil has no compatibility
with that of CFC-12 system.
•Use only Denso Oil 8, the manufacturer-autho-
rized compressor oil for the HFC-134a system.
•Do not mix multiple compressor oils.
If CFC-12 compressor oil is used in the HFC-134a
A/C system, the compressor may become stuck
due to poor lubrication, or the refrigerant may leak
due to swelling of rubber parts.
On the other hand, if HFC-134a compressor oil is
used in a CFC-12 A/C system, the durability of the
A/C system will be lowered.
•HFC-134a compressor oil is very hygroscopic.
When replacing or installing/removing A/C parts,
immediately isolate the oil from atmosphere using a
plug or tape. In order to avoid moisture, store the oil
in a container with its cap tightly closed.
3. REFRIGERANT
•CFC-12 refrigerant cannot be used in a HFC-
134a A/C system. HFC-134a refrigerant, also can-
not be used in a CFC-12 A/C system.
•If an incorrect or no refrigerant is used, it will re-
sult in poor lubrication and the compressor itself
may be damaged.
4. HANDLING OF REFRIGERANT
•The refrigerant boils at approx. –30°C (22°F).
When handling it, be sure to wear protective gog-
gles and protective gloves. Direct contact of the re-
frigerant with skin may cause frostbite.
If the refrigerant gets into your eye, avoid rubbing
your eyes with your hands. Wash your eye with
plenty of water, and receive medical treatment from
an eye doctor.
•Do not heat a service can. If a service can is di-
rectly heated, or put into boiling water, the inside
pressure will become extremely high. This may
cause the can to explode. If a service can must be
warmed up, use warm water of 40°C (104°F) or less.
•Do not drop or subject a service can to impacts.
(Observe the precautions and operation procedure
described on the refrigerant can.)
•When the engine is running, do not open the
high-pressure valve of the manifold gauge. High-
pressure gas can back-flow resulting in an explo-
sion of the can.
•Provide good ventilation and do not work in a
closed area.
•In order to prevent global warming, avoid releas-
ing HFC-134a into the atmosphere. Using a refrig-
erant recovery system, discharge and recycle the
gas.
