INSTALLATION INFORMATION

WARNING: before carrying out any
work, make sure the power supply is
disconnected.
CAUTION:before carrying out any
work, put the proper individual pro-
tection devices on.
WARNING: the device must be
installed in compliance with the
national plant engineering rules.
WARNING: electrical wiring, instal-
lation 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
systems for the purposes of safety and
correct operation.
WARNING: Install a device, main
switch, or electric plug so you can
fully disconnect the device from the
power supply.
WARNING: Consult all documenta-
tion before starting the installation.
The essential indications to carry out a
proper installation are given below.
The installer's experience will be neces-
sary however, to perfect all the opera-
tions in accordance with the specific
requirements.
The water, condensate discharge and
electrical circuit ducts must be pro-
vided for.

INSTALLING THE UNIT

To install the unit, proceed as follows:
- For wall mounting, maintain a minimum
distance of 160mm from the floor;
- For ducted installation, provide the fit-
ting of the channels to the unit, see the
drawing with the dimensional data. The
delivery outlet is already provided with
coupling flange.
- Use expansion bolts (not supplied) for
wall or ceiling installation, finally make
sure that the unit is installed horizontally.
- For installation suspended from the
ceiling, use four M8 threaded rods to
support the frame. Secure the unit to
the 4 threaded rods using 8 nuts of
The fan coil must be installed in such a
position that the air can be distributed
throughout the room and so that there
are no obstacles (curtains or objects) to
the passage of the air from the suction
inlet and delivery outlet.
The fan coil should be installed in such a
way as to facilitate routine (filter clean-
ing) and special maintenance opera-
tions, as well as access to the air drain
valve on the side of the unit frame
(connections side).
Do not install units in rooms where there
are inflammable gases or acid or alka-
line substances that could irreparably
damage the aluminium-copper heat
exchanger or 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.
The VED unit is prepared for connection
with air ducting.
The VED fancoils are equipped with 5
speed motors, 3 operating speeds of
which can be selected by changing the
connections in the electrical box of the
motor. The fancoils are provided with
connections to the standard speed. See
the wiring diagram before changing the
motor connections.
If a three-way valve is installed, the mini-
mum water temperature sensor can be
installed in two locations:
which 4 self-locking nuts. Use the nuts
to adjust the height of the unit; finally,
check that the unit is installed in a hori-
zontal position
- WARNING: The fan coil must be
installed in a horizontal position, oth-
erwise the correct discharge of conden-
sate can not be guaranteed.
- Make the hydraulic connections as
described in the relative chapter.
- Make the condensate discharge con-
nection as described in the relative
chapter. The fan coils that work in heat
mode only do not require condensate
discharge.

- in its housing in the coil;
- on the delivery pipe up stream of the
valve.
Check the thermostat manual before
choosing the location of the minimum
water temperature sensor, according to
the preferred control logic. The thermo-
stat may need the settings of the dip-
switches changed.
CAUTION: After completing the
installation check the operation of the
condensate discharge system, the seal
of the hydraulic fittings, insulation of
ducts and pipes. Then perform a func-
tional test.
DANGER! Only qualified service per-
sonnel can access it.
- Make the electrical wirings as shown
in the relative chapter and in the wiring
diagrams.
- Install and connect any accessories.
- Start up the fan coil and check all the
components and functions are operat-
ing correctly.
