INTRODUCTION
This manual includes technical descriptions, installation instructions, assembly, maintenance and
technical data exclusively directed to qualified personnel involved in the installation and
maintenance of the product.
INTENDED USE
The product is artistically made and installed to allow a constant air exchange inside the room. The
recovery system can be generally installed in residential or public places.
The product is supplied with a ceramic heat exchanger that accumulates heat during the
extraction of hot air coming from the room while, during the air intake from the outside, the
device transfers to the inlet cold air, the thermal energy stored in the heat exchanger.
The product is designed for wall installation. The duct containing the heat exchanger is supplied
for walls with a maximum thickness of 400mm; the duct can be shorten to a minimum of 250mm.
The extracted or incoming air must not contain inflammable or explosive mixtures, chemical
vapors, dusts, oils and other pathogenic substances in general.

TECHNICAL PARAMETERS
The Heat Recovery System is categorized as a Class II product.
The protection level is IPX4.
The Heat Recovery System is projected for indoors installation. Working temperature is included
between -20°C and 50°C with maximum relative humidity of 80%.
The design of the Heat Recovery System is in continuous evolution, therefore, some models may
differ from those described in this manual.

INSTALLATION
Installation must only be carried out by properly qualified person.
Make sure that the main electrical supply in the installation room is disconnected before starting
the electrical operations of assembly.
The appliance must not be installed near curtains, drapes, etc. as these could compromise the
correct working of the product.
Make sure that, once installed, the fan blades are placed not less than 2,30m away from the floor
below to the product.
Before assembling or using this product, carefully read all the instructions in this manual and be
sure to own all the necessary material for the installation.
Scrupulously follow the instructions in this manual.
1) ASSEMBLY
Once the area of installation is selected, mark the center of the hole to be realized on the wall
Make sure that on internal and external walls there is enough space, for a radius of 15 cm from
the center, thus corresponding to the product overall dimensions. Therefore make sure that,
within this area, there are not any interferences with other walls or non-removable objects.
Hole diameter for installation is Ø160mm
The duct must be installed through the hole, with a slight downward slope of 1° - 2° towards the
outsight to allow proper discharge of condensation.
To use the supplied recessed duct, the thickness of the wall must not exceed 400mm.

26
To install the product, the wall thickness cannot be less than 250mm.
Once obtained the hole, put the recessed duct (6) into the wall.
Make sure that the length of the recessed duct (6) is equal to the thickness of the wall.
The duct must end with the internal and external surfaces of the wall.
The quote “M” cannot be less than 250mm. In this case the wall is not appropriate to install the
product.
Adapt the duct if necessary, to the thickness of the wall with suitable tools, in the best way as
shown below:

27
Once adapted the length of the recessed duct (6) to the exact thickness of the wall, put the
external wall- mounting part (4e) on the external wall as shown in the picture below:
Insert the centering diameter of the wall-
mounting part (4e) inside the recessed duct
(6).
Once centered in the duct, mark the fixing holes on the external wall using the external wall-
mounting part (4e) through a level measure tool to ensure a proper installation as shown in the
picture below:
Make the holes and insert the expansion plug for the wall mounting.
Fix the external wall-mounting part (4e) on the external wall.

28
Fix the external conveyor (5) on the external wall mounting part (4e) till the complete assembly, as
shown in the pictures below:
2) ELECTRICAL CONNECTIONS
Installation must only be carried out by qualified person. Make sure that the voltage of the
installation room is in compliance with the value declared on the product label.
Make sure that the main electrical supply in the installation room is disconnected before electrical
assembly operations.
Identify the version of the product and carefully read all the instructions related to electrical
connections.
As done by marking the external holes, insert the centering diameter of the internal wall-mounting
part (4i) within the recessed duct (6) as shown in the picture above.
By using a measure level tool, mark and make four holes to fix on the wall the internal wall-
mounting part (4i).

29
Unlike the external wall mounting part, on the internal wall is necessary to bring the power supply
conductors to connect them to the stripped wires supplied with the product.
Provide an output for the wires, as the highlighted area shown in the picture
.
Once the expansion plugs for the wall mounting are inserted, carefully check all the electrical
operation before proceeding with the installation.
