STANDARD PROCEDURE
REFRIGERANT SYSTEM SERVICE EQUIPMENT
WARNING: Eye protection must be worn when servicing an A/C refrigerant system. Turn all valves off
(rotate clockwise) on the equipment being used before connecting or disconnecting service equipment from
the refrigerant system. Failure to observe these warnings may result in personal injury or death.
WARNING: Refer to the applicable warnings and cautions for this system before performing the following
operation (Refer to 24 - HEATING & AIR CONDITIONING/PLUMBING - WARNINGS) and (Refer to 24 - HEAT-
ING & AIR CONDITIONING/PLUMBING - CAUTIONS). Failure to follow the warnings and cautions could result
in possible personal injury or death.
When servicing the A/C system, a R-134a refrigerant
recovery/recycling/charging station that meets SAE
standard J2210 must be used (1). Contact an automo-
tive service equipment supplier for refrigerant recov-
ery/recycling/charging
equipment.
Refer
to
the
operating instructions supplied by the equipment man-
ufacturer for proper care and use of this equipment.
A manifold gauge set (1) may be needed with some
recovery/recycling/charging equipment. The manifold
gauge set should have manual shut-off valves (2 and
6), or automatic back-flow valves located at the ser-
vice port connector end of the manifold gauge set
hoses (4 and 5). This will prevent refrigerant from
being released into the atmosphere.
