The pipe must be heat, flame and corrosionproof. The manufacturer strongly advises against the
use of reducers or pipes with different diameter to the hood outlet pipe, and pipes made of
flexible aluminium because performance is diminished and noise level increased.
The end part of the pipe, on the outside of the hole on the wall, must be of such a shape to
avoid rain, gusts of wind or other foreign bodies getting into the pipe. Should there be any doubt,
contact anyone specialising in the installation of gas or ventilation system and not to reduce air
flow.
AIRFLOW ADJUSTMENT
Forced ventilation:
■Rotate the screw counterclockwise 360° (image 7 point 1).
■Move the plate (image 7 point 2) in the desired position corresponding to the diagram, shown
in the graphic of image F.
■Rotate the screw clockwise until it is fixed (image 7 point 3).
■Measure the Pm pressure to check that the value of the desired forced ventilation is obtained
with reference to diagram of image F.
Basic ventilation (if recommended):
■Remove the screw (image 8 point 1).
■Remove the existing valve plate (image 8 point 2).
■Insert the supplied plate with the curved side (image 9 point 3).
■Move the plate with the curved side (image 10 point 4) in the desired position corresponding
to the desired value shown in the graphic of the image G.
■Insert the screw rotating it clockwise until it is fixed. (image 10 point 5)
■Measure the Pm pressure to check that the wished basic ventilation value is obtained with
reference to diagram of image G.
BEFORE ELECTRICAL INSTALLATION
Before connection you must:
■check that the electrical data indicated are in conformity with the main voltage and frequency
values of the building where the hood is to be installed;
■check that the building is fitted with electric safety systems to protect against short circuits
and electric shock systems, according to the laws in force;
■install an electric socket (or connection point) with a bipolar switch, which has contacts with
an opening of at least 3 mms;
■if it is wished to install the hood with a plug, it is necessary that you have access to the
plug;
■always turn off the main voltage supply by means of the bipolar switch before connecting
and switch on again only when connections have been completed, tested and are safe.
ELECTRICAL CONNECTION
WARNING
The electrical connection can only be carried out by qualified professional personnel, using
standard material and state of the art installation methods. The manufacturer declines any
responsibility for installations carried out by unskilled persons and for installations which are not
