• Allow components stored in cool areas to warm to working area temperature before removing seal
caps. This prevents condensation from forming inside A/C components.
• Thoroughly remove moisture from the refrigeration system before charging the refrigerant.
• Always replace used O-rings.
• When connecting tube, apply the specified A/C oil to circle of the O-rings as shown. Be careful not to
apply oil to threaded portion. Refer to MTC-88, "
Oil".
• O-ring must be closely attached to dented portion of tube.
• When replacing the O-ring, be careful not to damage O-ring and tube.
• Connect tube until you hear it click, then tighten the nut or bolt by hand until snug. Make sure that
the O-ring is installed to tube correctly.
• After connecting line, perform leak test and make sure that there is no leakage from connections.
When the refrigerant leaking point is found, disconnect that line and replace the O-ring. Then tighten
connections of seal seat to the specified torque.
Precaution for Service of CompressorINFOID:0000000001704280
•Plug all openings to prevent moisture and foreign matter from entering.
•When the compressor is removed, store it in the same position as it is when mounted on the car.
•When replacing or repairing compressor, follow “Maintenance of Oil Quantity in Compressor”
exactly. Refer to MTC-16, "
Maintenance of Oil Quantity in Compressor" .
•Keep friction surfaces between clutch and pulley clean. If the surface is contaminated, with oil, wipe
it off by using a clean waste cloth moistened with thinner.
•After compressor service operation, turn the compressor shaft by hand more than five turns in both
directions. This will equally distribute oil inside the compressor. After the compressor is installed,
let the engine idle and operate the compressor for one hour.
•After replacing the compressor magnet clutch, apply voltage to the new one and check for usual
operation.
Precaution for Service EquipmentINFOID:0000000001704281
RECOVERY/RECYCLING 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.
ELECTRONIC LEAK DETECTOR
Be certain to follow the manufacturer’s instructions for tester operation and tester maintenance.

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 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 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.
Precaution for Leak Detection DyeINFOID:0000000001704282
• The A/C system contains a fluorescent leak detection dye 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 painted body panels or interior components. If dye is spilled,
clean immediately with the approved dye cleaner. Fluorescent dye left on a surface for an extended period of
time cannot be removed.
• Do not spray the fluorescent dye cleaning agent on hot surfaces (engine exhaust manifold, etc.).
• Do not 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. Do not use HFC-
134a (R-134a) leak detection dye in CFC-12 (R-12) A/C system or CFC-12 (R-12) leak detector dye in HFC-
134a (R-134a) A/C system or A/C system damage may result.
• The fluorescent properties of the dye will remain for over three (3) years unless a compressor malfunction
occurs.
IDENTIFICATION LABEL FOR VEHICLE
Vehicles with factory installed fluorescent dye have this identification label on the front side of hood.
NOTE:
• Vehicles with factory installed fluorescent dye have a green label.
• Vehicles without factory installed fluorescent dye have a blue label.

Maintenance of Oil Quantity in CompressorINFOID:0000000001704289
The oil in the compressor circulates through the system with the refrigerant. Add oil to compressor when
replacing any component or after a large refrigerant leakage occurred. It is important to maintain the specified
amount.
If oil quantity is not maintained properly, the following malfunctions may result:
• Lack of oil: May lead to a seized compressor.
• Excessive oil: Inadequate cooling (thermal exchange interference)
OIL
OIL RETURN OPERATION
Adjust the oil quantity according to the test group shown below.
1.CHECK OIL RETURN OPERATION
Can oil return operation be performed?
• A/C system works properly.
• There is no evidence of a large amount of oil leakage.
CAUTION:
If excessive oil leakage is noted, do not perform the oil return operation.
OK or NG
OK >> GO TO 2.
NG >> GO TO 3.
2.PERFORM OIL RETURN OPERATION, PROCEEDING AS FOLLOWS
1. Start engine, and set the following conditions:
- Engine speed: Idling to 1,200 rpm
- A/C blower switch: ON
- Blower speed: Max. position
- Temp. control: Optional [Set so that intake air temperature is 25° to 30°C (77° to 86° F)].
- Intake position: Recirculation (REC)
2. Perform oil return operation for about 10 minutes.
3. Stop engine.
>> GO TO 3.
3.CHECK REPLACEMENT PART
Should the compressor be replaced?
YES >> GO TO "OIL ADJUSTING PROCEDURE FOR COMPRESSOR REPLACEMENT".
NO >> GO TO "OIL ADJUSTING PROCEDURE FOR COMPONENTS REPLACEMENT EXCEPT COM-
PRESSOR".
