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 outdoor unit.
· Make sure the piping up to the joint is straight for more than 19-11/16in. Do not bend
