3.2. System Design
3.2.1. Basic Refrigerating System Confi guration
Using the DX-kit enables indoor units manufactured by other than Fujitsu general to be
used in the Fujitsu general refrigerant system.

3.2.2. Basic DX-kit System Confi guration
(1) System Pattern 1
External controllers (DDC) not manufactured by Fujitsu general control the Fujitsu general
outdoor units and indoor units (refrigerant cycle devices, etc.) not manufactured by Fujitsu
general. With this system, control using a Fujitsu general VRF controller is not possible.
