• When the compressor is removed, store it in th e same way as it is when mounted on the vehicle.
Failure to do so will cause oil to enter the low-pressure chamber.
• Use always a torque wrench and a b ack-up wrench when connecting tubes.
• Plug immediately all openings to prevent entry of dust and mois ture after disconnecting tubes.
• Connect the pipes at the final stag e of the operation when installing an air conditioner in the vehicle.
Do not remove the seal caps of pipes and other comp onents until just before required for connec-
tion.
• 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.
• Remove thoroughly moisture from the refriger ation system before charging the refrigerant.
• Replace always used O-rings.
• Apply oil to the O-rings shown in illustrations wh en connecting tubes. Be careful not to apply oil to
threaded portion.
• O-ring must be closely attached to the groove portion of tube.
• Be careful not to damage O-ring and tube when replacing the O-ring.
• Connect tube until a click can be heard. Then tighten the nut or bolt by hand. Check that the O-ring is
installed to tube correctly.
• Perform leak test and make sure there are no leaks from connections after connecting lines. Discon-
nect that line and replace the O-ring when the refrigerant leak point is found. Then tighten connec-
tions of seal seat to the specified torque.
COMPRESSOR
CAUTION:
• Plug all openings to prevent moisture and foreign matter from entering.
• When the compressor is removed, store it in the same way as it is when mounted on the vehicle.
• Follow “MAINTENANCE OF OIL LEVEL” exactly when replacing or repairing compressor. Refer to HA-22, "
Description".
• Keep friction surfaces between clutch and pulley clean . Wipe them off by using a clean waste cloth
moistened with solvent if the su rfaces are contaminated with oil.
• Turn the compressor shaft by hand more than fi ve turns in both directions after compressor service
operation. This equally distribut es oil inside the compressor. Let the engine idle and operate the
compressor for one hour after the compressor is installed.
• After replacing the compressor magnet clutch, appl y voltage to the new clutch to check for normal
operation.
LEAK DETECTION DYE
CAUTION:
• The A/C system contains a fluorescent leak detect ion dye used for locating refrigerant leaks. An
ultraviolet (UV) lamp is required to il luminate the dye when inspecting for leaks.
• Always wear fluorescence enhancing UV safety goggles to protect eyes and enhance the visibility of
the fluorescent dye. Name : A/C System Oil Type: DH-PR

< PRECAUTION >[MANUAL AIR CONDITIONING]
PRECAUTIONS
• The fluorescent leak detection dye is not a replacem
ent for an electronic leak detector. The fluores-
cent leak detection dye should be u sed in conjunction with an electronic leak detector to pin-point
refrigerant leaks.
• Read and follow all manufacture’s operating inst ructions and precautions prior to performing the
work for the purpose of safet y and customer’s satisfaction.
• A compressor shaft seal should not necessarily be repaired becau se of dye seepage. The compres-
sor shaft seal should only be repaired after conf irming the leak with an electronic leak detector.
• Always remove any remaining dye from the leak area after repairs are completed to avoid a misdiag-
nosis during a future service.
• Do not allow dye to come into contact with painted body panels or interior components. Clean imme- diately with the approved dye cl eaner if dye is spilled. 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 detection
dye in HFC-134a (R-134a) A/C system, or A/C system damage may result.
• The fluorescent properties of the dye remains fo r 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.

RECOVERY/RECYCLING RECHARGING EQUIPMENT
Be certain to follow the manufacturer’s instructions for machine operation and machine maintenance. Do not
introduce any refrigerant other than that specified into the machine.
ELECTRICAL LEAK DETECTOR
Be certain to follow the manufacturer’s instruct ions for tester operation and tester maintenance.
VACUUM PUMP
The oil contained inside the vacuum pump is not compatible with the
specified oil for HFC-134a (R-134a) A/C systems. The vent side of
the vacuum pump is exposed to atmospheric pressure. Vacuum
pump oil may migrate out of the pump into the service hose. This is
possible when the pump is switc hed OFF after evacuation (vacuum-
ing) and hose is connected to it.
To prevent this migration, use a manual valve placed near the hose-
to-pump connection, as per the following.
• Vacuum pumps usually have a manual isolator valve as part of the pump. Close this valve to isolat e 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 no vacuum condition. Such valves may restrict the pump’s
ability to pull a deep vacuum and are not recommended.
