Fan must be fixed to stationary housing with appropriate screws according to this guide.
This appliance is not intended to be built as a partition fan.
The electrical connection must correspond to this installation guide and enclosed connecting
diagram as desribed in chapter 4. INSTALLATION AND CONNECTION - page 6 of this
document.
Means for disconnection must be incorporated in the fixed wiring in accordance with the wiring
