• 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 system.
• 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.
Use only service equipment that is U.L.-listed and is
certified to meet the requirements of SAE J2210 to
remove HFC-134a (R-134a) from the air conditioning
system.
If accidental system discharge occurs, ventilate 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.
1. Connect a R-134a refrigerant recovery/recycling/
charging station (A) to the high-pressure service
port (B) and the low-pressure service port (C), as
shown, following the equipment manufacturer's
instructions.

and disconnect the charging station fittings.
Select the appropriate units of measure for your
refrigerant charging station.
Refrigerant capacity with rear A/C:

0.60 to 0.65 kg
1.3 to 1.4 lbs
21.2 to 22.9 oz
3. Check the system for leaks using a R-134a
refrigerant leak detector with an accuracy of 14 g
(0.5 oz) per year or better.
