Why the DX KIT can not connect VR-Ⅱ or VR-Ⅳ series?

>DX-Kits that exceed the following Capacity cannot be connected to the VR-Ⅱ or VR-Ⅳ series.
Cooling Capacity 28KW
Heating Capacity 31.5KW

If the Cooling Capacity exceeds 28KW, Drag and Drop is not possible.

This is because the two VX90A configurations of DX KIT (EEV UNIT) cannot be used with VR-Ⅱ or VR-Ⅳ.
