Heating and Air Conditioning
A/C Service Tips and Precautions
Compressed air mixed with R- 134a forms a
combustible vapor.
The vapor can burn or explode causing serious
injury.
Never use compressed air to pressure test
R-134a service equipment or vehicle air
conditioning systems.
Air conditioning refrigerant or lubricant vapor
can irritate your eyes, nose, or throat.
Be careful when connecting service equipment.
Do not breathe refrigerant or vapor.
The air conditioning system uses HFC-134a (R-134a)
ref rigerant and polyalkyleneglycol (PAG) ref rigerant oil,
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 aftempt to use R 12
servicing equipment; damage to the air conditioning
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-134a from the air conditioning system.
lf accidental system discharge occurs, ventilate the
work area before resuming service.
R-134a service equipment or vehicle air conditioning
systems should not be pressure tested or leak tested
with compressed air.
Additional health and safety information may be
obtained from the refrigerant and lubricant
manufacturers.
. Always disconnect the negative cable from the
battery whenever replacing air conditioning parts.
. Keep moisture and dirt out of the system. When
disconnecting any lines, plug or cap the fittings
immediately; don't remove the caps or plugs until
iust be{ore you reconnect each line.' Before connecting any hose or line, apply a few drops
of relrigerant oil to the O-ring.. When tightening or loosening a fitting, use a second
wrench to support the matching fitting.. When discharging the system, use a R-'134a
ref rigerant recovery/recycling/charging station; don't
release refrigerant into the atmosphere.

. To avoid contamination. do not return the oilto the
container once dispensed, and never mix it with other
refrigerant oils.. lmmediately af'ter using the oil, reinstallthe cap on

damage the paint. lf it gets on the paint, wash it off
immediately.
