.
The extraction fan or transformer (SELV models) is suitable for connection to
220-240V 50Hz supply.
The
Transformer (SELV models only)

C. SETUP
Accessing the commissioning menu
To configure the fan first remove the grille. With the grille removed the control board is
visible (Fig.7). Do NOT isolate the fan from the power
supply as configuration requires power to the fan;
removing the grille will automatically stop the impeller
from spinning
.
Once the fan has been commissioned please write the
installation date in the box on the label provided.
IMPORTANT
Do NOT
attempt to remove the circuit board cover (Fig.7). This
covers the high voltage power supply, preventing the risk of an
electric shock.
