PREFACE
The VRV System Inverter K Series is designed for easy installation and maintenance. Although it has all
the features of the previous VRV System Inverter Series, the method of displaying the model name has
been changed in order to conform to revision in Japanese Industrial Standards, the method of transmission
between outdoor and indoor units has been changed, the equipment has been modified so the same wiring
is used for transmission between indoor/outdoor units and centralized control, and can now be connected
with a central remote controller.
This maintenance manual was published in order to help you get a solid understanding of these functions,
and so you can provide fast and reliable after sales service. Although the contents of the manual may be
insufficient in some areas, we hope that you will use it to the best of your ability.
The service manual for the VRV PLUS Series (cool/heat selection system) explains the new methods
(super piping and super wiring) featured by the system in four sections: Outline, Functions, Test Operation
and Troubleshooting.
Compared with previous VRV Inverter System equipment,the VRV PLUS series is designed to facilitate
construction and save space, and is equipped with a unique service mode. The manual is intended for use
when troubleshooting or executing test operation.
If you find the manual to be insufficient in any of its explanations, please let us know so we can improve on
later editions.
