Precautions for Refrigerant ConnectionNJS00006
A new type refrigerant connection has been introduced to all refrigerant lines except the following location.
Expansion valve to evaporator
Refrigerant pressure sensor to liquid tank
ABOUT ONE-TOUCH JOINT
Description
One-touch joints are pipe joints which do not require tools during piping connection.
Unlike conventional connection methods using union nuts and flanges, controlling tightening torque at
connection point is not necessary.
When removing a pipe joint, use a disconnector.
COMPONENT PARTS
FUNCTIONS OF COMPONENT PARTS
NOTE:
Garter spring (2) cannot be removed from cage (A) of male-side piping.
Indicator ring (3) remains near piping connection point, however, this is not a malfunction. (This is to
check piping connection during factory assembly.)
1 Pipe (Male-side)Retains O-rings (4).
Retains garter spring (2) in cage (A).
2 Garter spring Anchors female-side piping (5).
3 Indicator ringWhen connection is made properly, this is ejected from male-side piping (1). (This part is no longer
necessary after connection.)
4 O-ring Seals connection point. (Not reusable)
5 Pipe (Female-side)
Seals connection by compressing O-rings (4).
Anchors piping connection using flare (B) and garter spring (2).

WARNING:
Make sure all refrigerant is discharged into the recycling equipment and the pressure in the system is
less than atmospheric pressure. Then gradually loosen the discharge side hose fitting and remove it.
CAUTION:
When replacing or cleaning refrigerant cycle components, observe the following.
When the compressor is removed, store it in the same way at it is when mounted on the car. Fail-
ure to do so will cause lubricant 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 dust and moisture.
When installing an air conditioner in the vehicle, connect the pipes at the final stage of the opera-
tion. Never 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 tubes, apply lubricant to circle of the O-rings shown in illustration. Be careful
not to apply lubricant to threaded portion.
O-ring must be closely attached to the groove of tube.
When replacing the O-ring, be careful not to damage O-ring and tube.
Connect tube until a click can be heard, then tighten the nut or bolt by hand. 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.
