Mounting example
The fan casing is mounted during construction works and connected to the main ventilation shaft. Electric wiring for connection of the VNV-1 80 ventilation unit is led out through a special hole in the casing. The front panel is covered with the protective cardboard plate supplied with the unit to avoid damages or contamination during finishing works in the room. After finishing the works the protective cardboard plate is removed and the VNV-1 80 ventilation unit is installed into the casing and connected to the wiring.
