Recommendations
The electrical connection and the installation of the extract fan should be made in accordance with the
�
laws enforced in each country.
For a correct electrical installation a single pole switch should be used with a gap of at least 3 mm.
�
between contacts.
In bathrooms, the unit must be installed in such a way that it is out of reach of a person in the shower or
�
bath. The switch must be installed outside the bathroom.
In case of high humidity, it is advisable to install the duct outlet horizontally with a slight downward
�
inclination to facilitate moisture run off.
