Before connecting the equipment to the electrical mains power supply, check that:
• voltage supply corresponds with what is reported on the identiication plate located
inside the hood;
• the electrical system is compliant and can withstand the load of the equipment (refer to
the technical speciications on the identiication plate located inside the hood);
• once connected, the plug and cable do not come into contact with hot parts having
temperatures that exceed 70°C
• the power supply system is efectively and properly connected to earth in compliance
with regulations in force.
the socket outlet to connect the installed equipment is within reach.
Some types of equipment can be equipped with a cable without a plug; in this case, the
type of plug to use is a "standardised" one, keeping in mind that the yellow-green wire must
be used for earthing, the blue wire must be used for neutral, and the brown wire must be
used for the phase.
The power supply cable must be assembled with a plug suitable for the load and connected
to an adequate safety plug.
If the ixed equipment is not provided with a power supply cable and plug, or any other
device that ensures disconnection from the electrical mains, with an opening gap of the
contacts that enables total disconnection in overvoltage category III conditions, said discon-
nection devices must be provided in the mains power supply in compliance with installation
regulations.
The yellow/green earth cable must not be cut of by the switch.
The Manufacturer declines all responsibility for failure to comply with the safety regulations.

EXTERNAL EXHAUST HOOD VERSION (SUCTION)
If the fumes outlet pipe passes through cold environments such as attics, etc., it is possible
that water condensation forms due to sudden changes in temperature. In this case, you are
required to insulate the pipes.
The hood is supplied with a check valve whose function is to prevent any external air ex-
change when the hood is not operating: for further information, refer to the assembly in-
structions chapter on page 28.
When the kitchen hood is used simultaneously with other appliances that use gas or
other fuels, the room must have suicient ventilation, in accordance with regulations
in force.
Deviation for Germany: when the kitchen hood is used at the same time as appliances that are
powered by energy other than electricity, the negative pressure in the room must not exceed 4 Pa
(4 x 10-5 bar).
HOOD VERSION WITH INTERNAL RECIRCULATION (FILTERING)
Hood not suitable for active carbon ilter assembly, therefore, the internal recirculation ver-
sion cannot be installed.
ASSEMBLY INSTRUCTIONS
ied to assemble the hood)
Before installing the hood, make sure the false ceiling has been duly rein-
forced to safely support the device: the weight of the hood, in various as-
sembly conigurations, is reported in the technical speciications inserted
in the irst part of this booklet.

• Make a hole in the false ceiling as indicated in Fig.

have reinforced proiles, keep a minimum distance of 60mm from the drilling perimeter

(Fig. ).

In this version, the kitchen fumes and vapours are
conveyed outside through an exhaust pipe.
The air outlet itting of the motor must be connect-
ed to the pipe that conducts the fumes and vapours
to an external outlet.
Do not connect the equipment to discharge
pipes of fumes produced from combustion (for
example boilers, ireplaces, etc) and you are to
comply with the regulations in force regarding
external air discharge.
The fumes outlet pipe must have:
- a diameter, or diameters, not less than that of the
hood itting
- a slight slope downwards (drop) in the horizontal
sections to prevent any formation of condensation
from lowing back to the hood;
- the minimum required number of bends;
- minimum required length (long pipes with various
bends can reduce suction performance of the hood
and trigger vibrations of the check valve).

• Check that the supplied laps (H) of the protection template (G) are bent on the opposite
side to the one with the double-sided adhesive tape. If not, bend them with a suitable

tool (e.g. grippers) (Fig. ).
• Remove the ilm from the doubled-sided adhesive tape already applied on the protec-

anchors and eyes (Fig. ).
The screw anchors supplied with the hood can only be used on masonry
ceilings: should it be necessary to install the hood on ceilings of diferent mate-
rial, assess other ixing systems, keeping the wall's strength and the weight of the
hood in mind (indicated in the technical speciications inserted in the irst part of
this booklet).
• Fasten the safety chains to the eyes (Fig.

The hood can be installed in various conigurations, depending on where the motor
unit is placed (motor unit placed on the hood or under-roof unit (URS) or outdoor
(URE) remote motor).
Follow the instructions according to the desired installation.
MOTOR UNIT PLACED ON THE HOOD
MOTOR UNIT (UM) PLACED ON THE HOOD
The motor unit (UM) is connected directly to the hood.
The motor used in the motor unit (UM) is, by default, equipped with a
check valve already installed.

To enable any maintenance operations, once the position of the lange (FL) has been deter-
mined, before securing it to the component (FLF), remove the two fastening screws from
the element (SM), as indicated in the igures
The motor unit (UM) can also be installed on the hood in various positions in order to have
