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 installed on the vehicle.
Doing so will cause oil to enter the low-pressure chamber.
• When connecting pipes, always use a torque wrench and a back-up wrench.
• After disconnecting pipes, 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.
• Do not reuse O-rings.
• O-ring must be installed near the dented portion of pipe.
• When replacing the O-ring, be careful not to damage O-ring and pipe.
• 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 pipe correctly.
• After connecting pipe, 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.
Service Equipment
INFOID:0000000009269727
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 instructions for tester operation and tester maintenance.
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.
SERVICE HOSES
Be certain that the service hoses display the markings described
(colored hose with black stripe). All hoses must have positive shut-
off devices (either instruction or automatic) near the end of the hoses
opposite to the manifold gauge.

< PRECAUTION >
PRECAUTIONS
Do not 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. If an improper
connection is attempted, discharging and contamination may occur.
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.

Special Service Tool
INFOID:0000000009269728
The actual shape of Kent-Moore tools may differ from those of special service tools illustrated here.
HFC-134a (R-134a) Service Tool and Equipment
INFOID:0000000009269729
Do not mix HFC-134a (R-134a) refrigerant and/or its specified oil with CFC-12 (R-12) refrigerant and/or its oil.
Separate and non-interchangeable service equipment must be used for handling each type of refrigerant/oil.
Refrigerant container fittings, service hose fittings and service equipment fittings (equipment which handles
refrigerant and/or oil) are different between CFC-12 (R-12) and HFC-134a (R-134a). This is to avoid mixed
use of the refrigerants/oil.
Adapters that convert one size fitting to another must not be used refrigerant/oil contamination will occur and
compressor failure will result.
