NOTE)
1. "- - - -" in the figure show field supply piping.
2. About size of connection pipe refer the "engineering data of VRV III".
3. In case of install this kit observe follow conditions.
· Do not tilt the joint more than ±15˚.
Install the joint horizontally so that the caution label attached to joint
comes to the top.
· Do not install the joint vertically why it may cause the malfunction of

· Make sure the piping up to the joint is straight for more than 19-11/16in.
Do not bend the field piping within this range. If a straight field piping
more than 4-3/4in is connected, more than 19-11/16in of straight section
can be ensured.
