UNIT INSTALLATION

CAUTION: check that the power supply is disconnected
before performing operations on the unit.
CAUTION: wiring connections installation of the fancoil and
relevant accessories should be performed by a technician who
has the necessary technical and professional expertise to install,
modify, extend and maintain plants and who is able to check
the plants for the purposes of safety and correct operation.
The fancoil should be installed in such a way as to facilitate
routine (filter cleaning) and special maintenance operations, as
well as access to the air breather valve on the side of the unit
frame (connector side).
To install the unit, proceed as follows:
- Extract the air filter (FCX - AS model only).
- Remove the housing by loosening the screws (Figures 1 and 2),
or the rear cover panel in the case of wall models, sizes 17 to 50.
- In the case of wall-mounted FCX-AS unit, keep a minimum
clearance of 80 mm from the floor. In the case of floor-mount-
ed units on bases, refer to the instructions supplied with the
accessory.
- Use expansion plugs (not supplied) to secure the unit to the
wall or ceiling, as shown in figures 5 and 6.
To install hanging units with the AMP brackets, proceed as fol-
lows:
- fit the 4 brackets (1 in Fig. 8) to the sides of the unit; insert the
upper tab in the slot, then secure the lower part to the contact
block by means of the screws supplied;
- secure the flanges (2) to the ceiling by means of expansion

ELECTRICAL CONNECTIONS

CAUTION: make sure that electrical power to the machine
has been turned off before making electrical connections.
CAUTION: wiring operations and installation of the fancoil
and relative accessories should be performed by specialised
personnel only.
CONNECTION CABLE SPECIFICATIONS
Use H05V-K or N07V-K type with 300/500 V insulation piped
or ducted.
All cables must be piped or ducted until they are not placed
inside the fan coil.
The cables coming out of the pipe/duct must not be subjected
to stretch or twist. They must be protected from weather con-
ditions.
Stranded wires may only be used in connection with termi-
nating sleeves. It must be ensured that all individual wires are
correctly inserted in the sleeve.
All wiring diagrams are constantly updated. Please refer to
the ones supplied with the unit.
To protect fan coils against short circuits, always fit the
power cable to the units with 2A 250V (IG) thermo-magnetic
all-pole switches with a minimum contact gap of 3 mm.
Each control panel controls a single fancoil.
The assembling place must be chosen so that the max. and
min. room temperature limit is respected 0÷45°C (<85% U.R.).
The control panel may not be fitted on a metal wall unless this
is permanently connected to a grounded outlet.
The control panels consist simply of electric circuits connected
to the mains voltage of 230V; all the inputs for the sensors and
controls must therefore be correspondingly insulated for this
voltage.
Some control panels are fitted with a room temperature probe
and/or a water temperature probe. In addition, it is possible
to connect an external contact to the internal control board
(EX), allowing the remote control of the fan coil; consult the
plugs (not supplied); for the positions between the flanges and
the contact block, see the dimensional data.
- Make hydraulic connections.
Refer to the dimensional data for the position and diameter of
the hydraulic connectors.
Insulate water lines adequately or fit the condensate drainage
tray (available as an accessory) to prevent dripping during cool-
ing applications.
In case of horizontal installation, fit the condensate discharge
pipe (supplied separately) following the indications shown in
picture 10. The connection between pipe and drip tray must be
sealed with silicone.
The condensate drainage system should be of an adequate size
and be positioned to favour runoff (min. 1% slope). If conden-
sate is discharged into the sewage system, install a siphon to
prevent return of unpleasant odour into the room.
- Make the electrical connections as shown in the wiring dia-
grams.
- Remount the cover, or the front pannel, connect the ambient
sensor or the microswitch (if present).
- Refit the air filter.
65 mm
recapitulatory table and the manuals of the individual panels
to select the most suitable model.
The minimum water temperature probe makes it possible to
stop the ventilation automatically if the temperature of the
input water to the coil falls below 39°C.
In installations with a three-way valve, the minimum water
temperature probe must be relocated from its standard mount-
ing in the coil to the delivery hose upstream of the valve.
When relocating the water temperature probe, the standard
probe must be replaced with an accessory SW3 probe, fitted
with a cable of suitable length.
CAUTION: given that it is powered to 230 VAC, the probe
has double insulation.
When installing remote control panels with FCX-U version
fancoils, observe the relative wiring diagram; configure the
microswitch (MS) in the panel (controlling the opening of the
delivery grille) in series on the panel power supply.
Multifunction electronic thermostats are supplied ready to
operate in standard configuration, though can be adjusted to
the specific operating requirements by means of the internal
dip-switches.
Customised functions vary between models; for this reason,
consult the relative manuals.
Hanging versions with extra-strength motor (PO): select the
appropriate connections on the motor terminal board to ena-
ble three of the seven speeds available. The connections are
made by the manufacturer as shown in the picture 12.
WARNING: check whether the installation has been carried
out correctly. Follow the checking procedures indicated in
the manuals of the control panels.
