• 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).
• Remove always any remaining dye from the leakage area after repairs are completed to avoid a mis-
diagnosis during a future service.
• Never allow dye to come into contact with painted body panels or interior components. Clean imme-
diately 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 the 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, or A/C system damage may result.
• The fluorescent properties of the dye remains for three or more years unless a compressor malfunc-
tion occurs.
NOTE:
Identification
• Vehicles with factory installed fluorescent dye have a green label.
• Vehicles without factory installed fluorescent dye have a blue label.
Service Equipment
INFOID:0000000012197100
RECOVERY/RECYCLING RECHARGING EQUIPMENT
Be certain to follow the manufacturer’s 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’s 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 hose is connected to it.
To prevent this migration, use a instruction valve placed near the hose-
to-pump connection, as per the following.
• Vacuum pumps usually have a instruction isolator valve as part of the
pump. Close this valve to isolate the service hose from the pump.
• Use a hose equipped with a instruction 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 no vacuum condition. Such valves may restrict the pump’s
ability to pull a deep vacuum and are not recommended.
MANIFOLD GAUGE SET
RHA270DA
HA-8
< PRECAUTION >
PRECAUTIONS
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 black stripe). All hoses must equip positive shut-
off devices (either instruction 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
the 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
Using a charging cylinder is not recommended. Refrigerant may be vented into air from cylinder’s top valve
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.

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.
