UNIT INSTALLATION
WARNING: check that the power supply is disconnected
before performing operations on the unit.
WARNING: the electrical connections, the 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 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).
The assembly site must be chosen in such a way that the
maximum and minimum ambient temperature limits are
respected 0÷45°C (<85% U.R.).
To install the unit, proceed as follows:
- Remove the air filter.
- Undo the screws and remove the housing (Fig. 3).
- In case of wall-mounted FCX-A unit, keep a minimum

CONNECTION CABLES SPECIFICATIONS
Use H05V-K or N07V-K type cables with 300/500 V 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
ROTATING THE COIL
If hydraulic connections require the rotation of the coil, remove
the cover or the front panel and proceed as follows (Fig. 6):
– remove the screw (1) securing the control panel (2) to the
right side of the unit, then remove it by disconnecting the
electrical wirings;
– remove the screws and remove the coil case (4);
– remove the screws securing the coil (5), then remove the
coil;
– remove the push-outs (6) on the right hand side;
– r o t a t e t h e c o i l ( 5 ) a n d s e c u r e i t w i t h t h e
screws previously removed
– refit the cover (4), secure with the screws, then insert
the plastic plugs supplied (7) in the holes left free by
the hydraulic connections;
all the trays can be used for condensate drain on both sides.
In case of vertical installation, for condensate drain on the
right side, position the drain connection to the right (8).
– slide out the electrical wirings from the right side, remove

clearance of 80 mm from the floor. In the case of floor-
mounted units on feet, refer to the instructions supplied with
the accessory.
- Use expansion plugs (not supplied) to secure the unit to the
wall as indicated in Fig. 4.
- Make hydraulic connections.
Refer to the dimensional data for the position and diameter
of the hydraulic connections.
Insulate water lines adequately or fit the auxiliary condensate
drainage tray (available as an accessory) to prevent dripping
during cooling applications.
The condensate drain system should be of an adequate
size and be positioned to favour runoff (min. 1% slope).
If condensate is drained into the sewage system, install a
siphon to prevent return of unpleasant odour into the room.
- Make the electrical wirings as shown in the wiring diagrams.
- Refit the air filter.
to stretch or twist. They must be protected from weather
conditions.
Stranded wires can only be used with terminating sleeves.
Make sure that the strands of the wires are inserted properly.
When making the connections, follow the wiring diagrams
supplied with the equipment and shown in this document.
Wiring diagrams are constantly updated. It is therefore
compulsory to refer to the ones supplied with the unit.
To protect the unit against short circuits, fit an omnipolar
magneto-thermal trip 2A 250V (IG) to the power line with a
minimum contact opening distance of 3 mm.
Each control panel can control a single fan coil.
The control panels only comprise electric circuits connected
to a power supply of 230V;
the push-out and move the cable guide (9) from the right to
the left side;
– transfer the electrical wirings to the left side through the
cable guide (9);
– move the control board (10) and the ground jumper
connection (11) to the left side.
– refit the control panel on the left side and reconnect the
electrical wirings;
– in the FCX-A versions, the air filter must be adapted to the
new configuration changing the position of the external
support in relation to the filter frame (Fig. 1): press down
on the tab (1 Fig. 2) with a screwdriver while moving the
external support (2) until the tab is over the tooth (3).
Then release the tab so that the position between the support
and the filter is as shown in figure 1.
Given that the contact block on the unit is off-centre in
relation to the cabinet housing, the feet must also be
exchanged.
