INSTALLATION
WARNING: before carrying out any
intervention, check the power supply is
disconnected.
WARNING:before carrying out any
work, put the proper individual
protection equipment on.
WARNING: the appliance must be fitted
according to the national regulations on
process plant engineering.
WA R N I N G : e l e c t r i c a l w i r i n g s ,
installation of the fan coils and relevant
accessories should be performed 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
INSTALLING THE UNIT
- Choose the place where to install
the unit according to the layout of
the room, the number of units to be
installed and any limitations imposed
by the architecture. Check that the
chosen place facilitates installing and
servicing the unit.
- Install four M8 threaded rods into the
ceiling to hold the frame.
VEC allows 2 installation options thanks
to the grill prepared to be fixed in two
positions:
A) for suspended ceiling installation with
reduced space that requires units with
small dimensions.
B) allows (increasing total height)
to increase the difference in level
between condensate drain and
suspended ceiling by a further 30
mm, to make the realisation of the
condensate drain ducting even easier,
in order to prevent, in most cases,
the necessity for a condensate drain
pump.
To install the VEC unit, proceed as
follows:
- open the cardboard box
- if necessary, mount any accessory
before installing the unit on the ceiling
WARNING: consult the relevant
manuals of the accessories
- lift the unit carefully and, keeping it
ELECTRICAL WIRINGS
The unit must be connected directly
to an electrical outlet or to an
independent circuit.
To protect the unit against short circu-
its, fit an omnipolar thermal-magnetic
trip 2A 250V (IG) to the power line
with a minimum contact opening
distance of 3mm.

CONNECTION CABLES
Use H05V-K or N07V-K type cables
with 300/500V with insulation, piped
or ducted.
All the cables must be piped or ducted
until they are inside the fan coil.
The cables coming out of the pipe or
duct must not be subject to stretching
or twisting. They must be protected from
systems for the purposes of safety and
correct operation.
WARNING: install a device, main
switch or plug which allows to
completely cut off the power supply
from the unit.
Instructions which are essential for the
proper installation of the equipment are
given here.
The completion of all the operations
in accordance with the specific
requirements is however left to the
experience of the installation engineer.
Do not install units in rooms where
there are inflammable gases or acid
or alkaline substances that could
slightly inclined, attach it to the 4
threaded bars using 8 nuts, 4 of which
are self-locking. Operate the nuts
to adjust height; finally, check that
the unit is installed in a horizontal
position
- lay the hydraulic pipes through the
suspended ceiling to the attachment
plate on the unit
- make the hydraulic connections as
described in the relative chapter
- bring the condensate discharge pipe
so that it matches the relative fitting on
the condensate discharge device
external agents.
Stranded wires can only be used with
terminating sleeves. Make sure that the
strands of the wires are inserted pro-
perly.
Wiring diagrams are constantly upda-
ted. It is therefore compulsory to refer
to the ones supplied with the unit.

T H E
The control panel may not be fitted on
a metal wall unless this is permanently
connected to an earthed outlet.
The control panels consist simply of
electric circuits connected at the mains
voltage of 230V; all the inputs for the
probes and controls must therefore be
correspondingly insulated for this vol-
tage.
Multifunctional electronic thermostats
irretrievably damage the aluminium-
copper heat exchanger or the internal
plastic parts.
Do not install the unit in workshops or
kitchens where the oil vapours mixed
with the treated air can be deposited
on the exchange coils, reducing their
performance, or on the parts inside the
unit, damaging the plastic parts.
Choose a position at the centre of the
room whenever possible; adjusting the
air output allows air to be distributed
optimally within the room. Do not
install at a height above three metres.
- drain the system via the drain valve
- bring the power supply and the
control cables close to the electrical
box
- adjust the position of the unit from the
support bracket by means of the nuts
so that the unit is level and the frame
rests slightly on the suspended ceiling
- start the fan coil unit and carry out
an operation test; the functions are
described in the User Manual
Do not install at a height
above three metres.
are provided ready for operation in the
standard configuration but allow the
installer to adjust them to the specific
necessities of the system by modifying
the internal dip-switch configuration.
The functions that can be customised might
vary from model to model, for this reason it
is advisable to consult the relevant manuals.
WARNING:check whether the instal-
lation has been carried out correct-
ly. FOLLOW THE CHECKING PROCE-
DURES indicated in the control panel
manuals.
