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.
