INSTALLATION INFORMATION
WARNING: Disconnect the power
supply before carrying out any
intervention.
WA R N I N G : P r o v i d e a p p r o p r i a t e
personal protective equipment before
carrying out any intervention.
WARNING: The unit must be installed
in accordance with the applicable
national regulations.
WA R N I N G : w i r i n g c o n n e c t i o n s ,
installation of the fan coil units
and relevant accessories must be
per formed by a technician who
has the necessary technical and
professional expertise to install,
modify, extend and maintain systems
and who is able to check the system
for the purposes of safety and correct
operation.
WARNING: Install an electrical isolator
or plug that allows the electrical
power to be completely isolated from
the unit.
W A R N I N G : C o n s u l t
documentation before starting the
installation.
Instructions essential for the proper
installation of the equipment are shown
here.
The final touches to all the operations are
however left to the experience of the
installation engineer in accordance with
the specific needs.

INSTALLATION OF THE UNIT

To install the unit proceed as follows.
- For wall mounted installations maintain
a minimum distance of 160 mm from the
floor.
- For ducted installations provide the duct
connections to the unit and refer to
the drawing for dimensional data. The
discharge is provided with a connection
flange.
The outlet flange with connection to
ducting is supplied with the unit.
The elements of the discharge flange must
be assembled prior to being mounted
on the unit.
Some installations do not require the
outlet flange.

The water piping, condensate discharge
and electrical wiring must be installed
beforehand.
The fan coil unit must be installed in such
a position that the air can be distributed
throughout the room and that there are
no obstacles (curtains or objects) to the
passage of the air from the intake and
discharge.
The fan coil unit must be arranged in
such a way as to make easy ordinary
maintenance (filter cleaning) and special
maintenance, as well as the access to the
air vent valve on the side of the frame
(connections side).
Do not install the unit in locations
containing flammable gas and acid
o r alk ali ne sub s t a n ce s t h at c a n
permanently damage the copper-
aluminium heat exchanger or the
internal plastic components.
Do not install the unit in workshops or
kitchens where oil vapour mixed in the
air can be deposited on the coil, causing
performance reduction, or deposited on
a l l t h e
internal parts causing damage to the
plastic components.
The VES unit is designed for ducted air
connections.
The VES fan coil units are provided with
multi-speed motors. The 3 operating
speeds can be selected by modifying the
connections in the motor electric box.
The fan coil units are supplied with the
connections to the standard velocities.
- Carry out the installation and connection
of any accessories.
- For wall or ceiling installations use
expansion plugs (not provided) and
ensure the unit is installed level.
- For ceiling hung installations use four
M8 threaded rods to support the frame.
Fix the unit to the threaded rods using
8 nuts of which 4 are self locking nuts.
Adjust the nuts to ensure that the unit is
installed level.
- WARNING: The fan coil unit must be
installed perfectly level otherwise the
condensate may not discharge correctly.
- Carry out the hydraulic connections as
detailed in the relevant chapter. It is

Refer to the wiring diagram before
modifying the motor connections.
If the valve is installed the minimum
temperature water sensor can be
installed in two positions:
- in its mount in the coil
- to the flow tube upstream of the valve.
Refer to the thermostat manual before
selecting the position of the minimum
temperature water sensor, as a function
of the preferred control logic. The
thermostat may require changes to the
dip-switch internal settings.
WA R N I N G: Af ter completing the
installation check the operation of
the condensate discharge system, the
tightness of hydraulic connections,
and the insulation of the ducting and
piping. Then carry out a functional
test.
DANGER! Only maintenance qualified
personnel may access it.
WARNING: Keep the electrical connec-
tions separated from the hydraulic con-
nections. The hydraulic connections and
condensate discharge must be on the
opposite side to the electrical connec-
tions.
WARNING: If the power cord is dam-
aged it must be replaced by the manu-
facturer or its service agent or a simi-
larly qualified person in to prevent
any risk.
recommended that the water piping is
properly insulated.
- Carry out the condensate discharge
connection as detailed in the relevant
chapter. Fan coil units operating
as heating only do not require a
condensate discharge.
- Carry out the electrical connections as
detailed in the relevant chapter and as
shown on the electrical wiring diagrams.
- Start the fan coil unit and check the
operation of the components and all the
functions.
