Be certain that the service hoses display the markings described
(colored hose with black stripe). All hoses must include positive shut-
off devices (either manual or aut omatic) near the end of the hoses
opposite the manifold gauge.
SERVICE COUPLERS Never attempt to connect HFC-134a (R-134a) service couplers to a
CFC-12 (R-12) A/C system. T he HFC-134a (R-134a) couplers will
not properly connect to the CFC-12 (R-12) system. However, if an
improper connection is attempted, discharging and contamination
may occur.
REFRIGERANT WEIGHT SCALE Verify that no refrigerant other than HFC-134a (R-134a) and speci-
fied oils have been used with the scale. If the scale controls refriger-
ant flow electronically, the hose fitting must be 1/2 ″-16 ACME.
CHARGING CYLINDER Using a charging cylinder is not re commended. Refrigerant may be vented into air from cylinder’s top valve
when filling the cylinder with refrigerant. Also, the accura cy of the cylinder is generally less than that of an
electronic scale or of quality recycle/recharge equipment.
Precaution for Leak Detection Dye INFOID:0000000004307049
• The A/C system contains a fluorescent leak detection dy e used for locating refrigerant leaks. An ultraviolet
(UV) lamp is required to illuminate the dye when inspecting for leaks.
• Always wear fluorescence enhancing UV safety goggles to protect your eyes and enhance the visibility of
the fluorescent dye.
• The fluorescent dye leak detector is not a replacement for an electronic refrigerant leak detector. The fluo-
rescent dye leak detector should be used in conjunction with an electronic refrigerant leak detector to pin-
point refrigerant leaks.
• For your safety and your customer’s satisfaction, read and follow all manufacture’s operating instructions
and precautions prior to performing the work.
• A compressor shaft seal should not be repaired because of dye seepage. The compressor shaft seal should
only be repaired after confirming the leak with an electronic refrigerant leak detector.
• Always remove any remaining dye from the leak area after repairs are complete to avoid a misdiagnosis dur- ing a future service.
• Do not allow dye to come into contact with paint ed body panels or interior components. If dye is spilled,
clean immediately with the approved dye cleaner. Fluores cent dye left on a surface for an extended period of
time cannot be removed. RHA274D

PREPARATION
HFC-134a (R-134a) Servic e Tool and Equipment INFOID:0000000004307051
Never mix HFC-134a refrigerant and/or its specified oil with CFC-12 (R-12) refrigerant and/or its oil.
Separate and non-interchangeable service equipment must be used for handling each type of refrigerant/oil.
Refrigerant container fittings, service hose fittings and service equipment fittings (equipment which handles
refrigerant and/or oil) are different between CFC-12 (R-12) and HFC-134a (R-134a). This is to avoid mixed
use of the refrigerants/oil.
Adapters that convert one size fitting to another must never be used refrigerant/oil contamination will occur
and compressor failure will result.
