PRECAUTIONS
• Perform leakage test and check that there is no leakage from connections after connecting the line.
Disconnect the line and replace the O-ring when the refrigerant leakage point is found. Then tighten
the connections of seal seat to the specified torque.
Service Equipment
INFOID:0000000003072881
RECOVERY/RECYCLING EQUIPMENT
Be certain to follow the manufacturer instructions for machine operation and machine maintenance. Never
introduce any refrigerant other than that specified into the machine.
ELECTRICAL LEAK DETECTOR
Be certain to follow the manufacturer instructions for tester operation and tester maintenance.
VACUUM PUMP
The lubricant contained inside the vacuum pump is not compatible
with the specified lubricant for HFC-134a (R-134a) A/C systems.
The vent side of the vacuum pump is exposed to atmospheric pres-
sure. So the vacuum pump lubricant may migrate out of the pump
into the service hose. This is possible when the pump is switched
OFF after evacuation (vacuuming) and the hose is connected to it.
To prevent this migration, use a manual valve placed near the hose-
to-pump connection, as per the following procedure.
• Vacuum pumps usually have a manual isolator valve as part of the
pump. Close this valve to isolate the service hose from the pump.
• Use a hose equipped with a manual shut-off valve near the pump
end for pumps without an isolator. Close the valve to isolate the
hose from the pump.
• Disconnect the hose from the pump if the hose has an automatic
shut-off valve. As long as the hose is connected, the valve is open
and lubricating oil may migrate.
Some one-way valves open when vacuum is applied and close
under the no vacuum condition. Such valves may restrict the ability
of the pump to create a deep vacuum and are not recommended.

Be certain that the gauge face indicates HFC-134a or R-134a. Be
sure the gauge set has 1/2
″
-16 ACME threaded connections for ser-
vice hoses. Confirm the set has been used only with refrigerant
HFC-134a (R-134a) and specified lubricants.
SERVICE HOSES
Be certain that the service hoses display the markings described
(colored hose with a black stripe). All hoses must equip positive
shut-off devices (either manual or automatic) near the end of the
hoses opposite to the manifold gauge.
SERVICE COUPLERS
Never attempt to connect HFC-134a (R-134a) service couplers to a
CFC-12 (R-12) A/C system. The HFC-134a (R-134a) couplers do
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 lubricants have been used with the scale. The hose fitting must
be 1/2
″
-16 ACME if the scale controls refrigerant flow electronically.
CHARGING CYLINDER
Use of a charging cylinder is not recommended. Refrigerant may be vented into the air from the top valve of
the cylinder when filling the cylinder with refrigerant. Also, the accuracy of the cylinder is generally less than
that of an electronic scale or of quality recycle/recharge equipment.

COMPRESSOR
General Precautions
INFOID:0000000003072882
CAUTION:
• Plug all openings to prevent moisture and foreign material from entering.
• Store it in the same way as it is when mounted on the car when the compressor is removed.
• Follow “Maintenance of Lubricant Quantity in Compressor” exactly when replacing or repairing
compressor. Refer to
HA-25, "Maintenance of Lubricant Quantity"
• Keep friction surfaces between clutch and pulley clean. Wipe it off by using a waste moistened with
thinner if the surface is contaminated with lubricant.
• Turn the compressor shaft by hand more than five turns in both directions after compressor service
operation. This equally distributes lubricant inside the compressor. Let the engine idle and operate
the compressor for one hour after the compressor is installed.
• Apply voltage to the new compressor and check for normal operation after replacing the compressor
magnet clutch.

FLUORESCENT LEAK DETECTOR
General Precautions
INFOID:0000000003072883
CAUTION:
• The A/C system contains a fluorescent leak detection dye used for locating refrigerant leakages. An
ultraviolet (UV) lamp is required to illuminate the dye when inspecting for leakages.
• Always wear fluorescence enhancing UV safety goggles to protect eyes and enhance the visibility of
the fluorescent dye.
• The fluorescent dye leak detector is not a replacement for an electrical leak detector (SST: J-41995).
The fluorescent dye leak detector should be used in conjunction with an electrical leak detector
(SST: J-41995) to pin-point refrigerant leakages.
• Read and follow all manufacturer operating instructions and precautions prior to performing work
for safety and customer satisfaction.
• A compressor shaft seal should not necessarily be repaired because of dye seepage. The compres-
sor shaft seal should only be repaired after confirming the leakage with an electrical leak detector
(SST: J-41995).
• Always remove any remaining dye from the leakage area after repairs are completed to avoid a mis-
diagnosis during future service.
• Never allow dye to come into contact with painted body panels or interior components. Immediately
clean with the approved dye cleaner if dye is spilled. Fluorescent dye left on a surface for an
extended period of time cannot be removed.
• Never spray fluorescent dye cleaning agent on hot surfaces (engine exhaust manifold, etc.).
• Never use more than one refrigerant dye bottle [1/4 ounce (7.4 cc)] per A/C system.
• Leak detection dyes for HFC-134a (R-134a) and CFC-12 (R-12) A/C systems are different. Never use
HFC-134a (R-134a) leak detection dye in CFC-12 (R-12) A/C system or CFC-12 (R-12) leak detection
dye in HFC-134a (R-134a) A/C system, otherwise A/C system damage may result.
• The fluorescent properties of the dye remains for three or more years unless a compressor malfunc-
tion occurs.
IDENTIFICATION
NOTE:
Vehicles with factory installed fluorescent dye have a green label.
Vehicles without factory installed fluorescent dye have a blue label.
IDENTIFICATION LABEL FOR VEHICLE
Vehicles with factory installed fluorescent dye have an identification label on the front side of hood.

HFC-134a (R-134a) Service Tool and Equipment
• Never mix HFC-134a (R-134a) refrigerant and/or its specified lubricant with CFC-12 (R-12) refrigerant and/
or its lubricant.
• Separate and non-interchangeable service equipment must be used for handling each type of refrigerant/
lubricant.
• Refrigerant container fittings, service hose fittings and service equipment fittings (equipment that handles
refrigerant and/or lubricant) are different between CFC-12 (R-12) and HFC-134a (R-134a). This is to avoid
mixed use of the refrigerants/lubricant.
• Never use adapters that convert one size fitting to another. Refrigerant/lubricant contamination occurs and
compressor malfunction may result.
