PRECAUTIONS
O-Ring Part Numbers and Specifications
CAUTION:
When replacing or cleaning refrigerant cycle components, observe the following.
When the compressor is removed, store it in the same position as it is when mounted on the vehicle.
Doing so will cause oil to enter the low-pressure chamber.
When connecting tubes, always use a torque wrench and a back-up wrench.
After disconnecting tubes, immediately plug all openings to prevent entry of dirt and moisture.
When installing an air conditioner in the vehicle, connect the pipes as the final stage of the opera-
tion. Do not remove the seal caps of pipes and other components until just before required for con-
nection.
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.
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.

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 HA-19, "
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:0000000001396434
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.
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. So the vac-
uum pump oil may migrate out of the pump into the service hose.
This is possible when the pump is switched off after evacuation (vac-
uuming) and hose is connected to it.
To prevent this migration, use a manual valve placed near the hose-
to-pump connection, as follows.
Usually vacuum pumps have a manual isolator valve as part of the
pump. Close this valve to isolate the service hose from the pump.
For pumps without an isolator, use a hose equipped with a manual
shut-off valve near the pump end. Close the valve to isolate the
hose from the pump.
If the hose has an automatic shut-off valve, disconnect the hose
from the pump. 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 a no vacuum condition. Such valves may restrict the pump’s
ability to pull a deep vacuum and are not recommended.
MANIFOLD GAUGE SET
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 oils.

< PRECAUTION >
PRECAUTIONS
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 automatic) 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. 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:0000000001396435
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.
