This
vehicle uses
HFC-134a (R-134al refrigerant which does not
contain chlorofluorocarbons.
Pay
attention
to the follow-
ing
service items:
• Do not mix refrigerants CFC-l2
(R-l2) and
HFC-l34a (R-l34a). They are
not compatible.
• Use
only
the recommended polyalkyleneglycol (PAG) refrigerant oil (SP-l0) designed for the R-l34a
compressor.
Intermixing the recommended (PAGl refrigerant oil with any other refrigerant oil will result in compressor failure.
•
All
AJC
system
parts (compressor, discharge line,
suction
line, evaporator,
condenser,
receiver/dryer,
expansion
valve,
O-rings
for
joints) have to be proper for refrigerant R-134a. Do not confuse with R-12 parts.
•
Use
a
halogen
gas
leak detector designed for refrigerant R-134a.
•
R-12
and
R-134a refrigerant
servicing equipment
are not interchangeable. Use only
a
recovery/recycling/charging
station
that
is
U.L-listed
and is
certified
to meet the requirements
of
SAE J2210 to
service
R·
134a air
conditioning system
.
•
Always recover the
refrigerant
R· 134a with an approved
recovery/recycling/charging station before
disconnecting any
NC
fitting.
