1. Safety Precautions
A: HFC-134a AIR CONDITIONING
SYSTEM
Component parts of the cooling system,
refrigerant, compressor oil, and other parts are not
the same for the HFC-134a system and the older
CFC-12 system. Do not interchange parts or liquid.
Vehicles with HFC-134a air conditioning systems,
use only HFC-134a parts that are indicated on a
label (A) attached to the vehicle. Before performing
any maintenance, verify the type of air conditioning
system installed in the vehicle.
S4M0330A
B: COMPRESSOR OIL
Do not use any compressor oil that is not specifi-
cally designated for the HFC-134a air conditioning
system; only use ZXL200PG. Also, do not use
HFC-134a compressor oil in the CFC-12 air condi-
tioning system. If compression oils are mixed, poor
lubrication will result and the compressor itself may
be damaged.
Because HFC-134a compressor oil is very hygro-
scopic (easily absorbs moisture), when parts of the
air conditioning system are being removed, quickly
install a blind plug to prevent contact with the out-
side 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.
C: REFRIGERANT
Do not put CFC-12 refrigerant into a HFC-134a air
conditioning 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.
