Climate Control
A/C System Tests
Performance Test
The performance testwill help determine if the air
conditioner system is operating within specifications.
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.
lf 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 recover/recycling/
charging station to the high-pressure service port
and the low-pressure service port, following the
equipment manufacturer's instructions.
2. Oetermine the relative humiditv and air
temoerature.
. Compressed air mixed R-134a forms a
combustible vapor.
. The vapor can burn or explode causing serious
injury.
. Never use compressed air to pressure test R-134
a service equipment or vehicle air conditioning
svsrems.
. 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.
