1. Safety Precautions
1. HFC-134a AIR CONDITIONING SYSTEM
Component parts of the cooling system, refrigerant, com-
pressor oil, and other parts are not the same for the HFC-
134a system and the older CFC-12 system. Do not inter-
change parts or liquid.
Vehicles with HFC-134a air conditioning systems, use only
HFC-134a parts that are indicated on a label attached to
the vehicle. Before performing any maintenance, verify the
type of air conditioning system installed in the vehicle.
B4M0780
2. COMPRESSOR OIL
Do not use any compressor oil that is not specifically des-
ignated for the HFC-134a air conditioning system; only use
ZXL200PG. Also, do not use HFC-134a compressor oil in
the CFC-12 air conditioning system. If compression oils are
mixed, poor lubrication will result and the compressor itself
may be damaged.
Because HFC-134a compressor oil is very hygroscopic
(easily absorbs moisture), when parts of the air condition-
ing system are being removed, quickly install a blind plug
to prevent contact with the outside air. Also, always make
sure that the service container for compressor oil is tightly
closed except when in use. Store compressor oil in a tightly
closed steel container.

3. REFRIGERANT
Do not put CFC-12 refrigerant into a HFC-134a air condi-
tioning system. Also, do not put HFC-134a refrigerant into
a CFC-12 air conditioning system. If the wrong refrigerant
is used, poor lubrication will result and the compressor
itself may be destroyed.
G4M0979
4. HANDLING OF REFRIGERANT
Because refrigerant boils at approx. 30°C ( 22°F) at sea
level, it is cold enough to give you severe frostbite. Always
wear goggles to protect your eyes and gloves to protect
your hands. Also, even under the pressures normally found
in CFC-12 containers, refrigerant will boil with the addition
of heat. This could raise the pressure inside the container
to a dangerous level.
Never expose a can of HFC-134a to direct sunlight, or to
temperatures over 40°C (104°F). One more thing to
remember about HFC-134a is that when it is exposed to an
open flame or to hot metal, it forms phosgene, a deadly
gas. Do not discharge HFC-134a into the atmosphere on
purpose. Always read and follow the precautions on the
HFC-134a bottle.

2. Basic Information
1) The combination of moisture and refrigerant forms acid,
therefore, moisture should not be allowed to enter the
refrigerant.
2) Refrigerant oil readily absorbs moisture, therefore, keep
refrigerant oil containers tightly capped.
3) The process of evacuating the system is performed to
remove small amounts of moisture. This is accomplished
by lowering the pressure inside the system, which allows
the moisture to boil off, in much the same way that a pot
of water will boil away to nothing given enough time. The
evacuation process does not suck the moisture out of the
system.
4) A minimum level of vacuum must be reached to satis-
factorily evacuate the system. This minimum level of
vacuum depends on the temperature inside the system.
The chart below shows the level of vacuum required to boil
water at various temperatures.
Additionally, the vacuum level shown on a gauge will read
approx. 4 kPa (25 mmHg, 1 inHg) less for each 304.8 m
(1,000 ft) above sea level, due to the decrease in atmo-
spheric pressure at altitude.
