UNIT INSTALLATION
ELECTRICAL CONNECTIONS
ROTATING THE COIL
CAUTION: check that the power supply is dis-
connected 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 neces-
sary technical and professional expertise to
install, modify, extend and maintain plants
and who is able to check the plants for the pur-
poses 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:
- Remove the rear cover panel in the case of wall
models, sizes 17 to 56.
- In the case of floor-mounted units on bases,
refer to the instructions supplied with the acces-
sory.
- Use expansion plugs to secure the unit to the
wall or ceiling, (not supplied)
(chapter "drawings
- fig.2/fig.3")
To install hanging units with the AMP brackets,
proceed as follows:
- fit the 4 brackets
(chapter "drawings - fig.4")
to the sides of the unit (a); 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 (b) to the ceiling by means of
expansion plugs (not supplied); for the positions
between the flanges and the contact block, see
the dimensional data.
- Make hydraulic connections
(chapter "draw-
ings - fig.5")
Refer to the dimensional data for the position and
diameter of the hydraulic connectors.
Insulate water lines adequately or fit the conden-
sate drainage tray (available as an accessory) to
prevent dripping during cooling applications.
In case of horizontal installation, fit the conden-
sate discharge pipe (supplied separately) fol-
lowing the indications shown in picture 10. The
connection between pipe and drip tray must be
sealed with silicone
(chapter "drawings - fig.6")
.
The condensate drainage system should be of an
adequate size and be positioned to favour runoff
(min. 1% slope). If condensate 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 diagrams.
- Remount the front pannel, connect the ambient
sensor (if present).
- CAUTION: Keep separate electrical connections
from water connections.
Water connections and drain should be on the
side opposite of the electrical connections.
If connection of utilities to the unit requires
rotation of the coil, remove the cover or the
front pannel, then proceed as follows
(chapter
"drawings - fig.8")
:
– remove the condensate tray (a) (not present on
FCX - PV version);
– remove the coil cover sheet (b) by removing
the screws;
– remove the screws securing the coil (c), then
remove it;
– remove the push-outs (d) on the right side;
– rotate the coil (c), then secure it in the new
position with the screws previously removed;
– remount the coil cover sheet (b) and secure
it with screws, then insert the plastic plugs
(e) supplied in the openings left free by the
hydraulic connections;
all trays are designed to collect condensate on
both sides.
– to move condensate drainage to the right of
the unit, reverse discharge of the tray (a) (if pre-
sent), then transfer the drainage line (f) to the
right;
– slide out the electrical connections from the
right side, remove the push-out, then transfer
the cable guide (g) from the right to the left
side;
– transfer the electrical connections to the left
side through the cable guide (g);
– move the terminal block (h) and the ground
jumper connection (i) to the left side of the
unit.
CAUTION: make sure that electrical power to
the machine has been turned off before mak-
ing 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 insu-
lation 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 conditions.
Stranded wires may only be used in connec-
tion with terminating 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.
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 cir-
cuits 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 recapitulatory table and the manuals
of the individual panels to select the most suit-
able 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 mini-
mum water temperature probe must be relo-
cated from its standard mounting 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 suit-
able length.
CAUTION: given that it is powered to 230
VAC, the probe has double insulation.
Multifunction electronic thermostats are sup-
plied ready to operate in standard configuration,
though can be adjusted to the specific operat-
ing requirements by means of the internal dip-
switches.
Customised functions vary between models; for
this reason, consult the relative manuals.
The connections are made by the manufacturer
as shown in the picture
(chapter "drawings -
fig.7")
.
Hanging versions with extra-strength motor
(PO): select the appropriate connections on the
motor terminal board to enable three of the 6
speeds available (FCX 22-24-32-34-42-44-52-54
PO) or of the 7 speeds available (FCX 62-64-82-
84-102 PO).
WARNING: check whether the installation has
been carried out correctly. Follow the check-
ing procedures indicated in the manuals of
the control panels.
