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).

REMOVAL
1. Clean piping connection point, and set a disconnector.
2. Slide disconnector in axial direction of piping, and stretch garter spring with tapered point of disconnector.
3. Slide disconnector farther so that inside diameter of garter spring becomes larger than outside diameter of
female-side piping flare. Then male-side piping can be disconnected.
INSTALLATION
1. Clean piping connection points, and insert male-side piping into female-side piping.
2. Push inserted male-side piping harder so that female-side piping flare stretches garter spring.
3. If inside diameter of garter spring becomes larger than outside diameter of female-side piping flare, garter
spring seats on flare. Then, it fits in between male-side piping cage and female-side piping flare to anchor
piping connection point.
NOTE:
When garter spring seats on flare, and fits in between male-side piping cage and female-side piping flare,
it clicks.
CAUTION:
Female-side piping connection is thin and easy to deform. Slowly insert the male-side piping
straight in axial direction.
Insert piping securely until a click is heard.
