Unit Installation; Electrical Connections; Rotating The Coil - AERMEC FCX series Bedienungs- Und Installationsanleitung

Versions:
B (vertical installation, without
control panels).

UNIT INSTALLATION

CAUTION: check that the power supply
is disconnected before performing opera-
tions on the unit.
CAUTION: wiring connections installa-
tion of the fancoil and relevant accessories
should be performed by a technician who
has the necessary technical and profes-
sional 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

ELECTRICAL CONNECTIONS

CAUTION: make sure that electrical
power to the machine has been turned off
before making electrical connections.
CAUTION: wiring operations and instal-
lation of the fancoil and relative acces-
sories 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 con-
nection with terminating sleeves. It must
be ensured that all individual wires are
correctly inserted in the sleeve.
All wiring diagrams are constantly updat-
ed. 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.

ROTATING THE COIL

If connection of utilities to the unit requires
rotation of the coil, remove the cover or
the front pannel, then proceed as follows
(Fig. 9):
– remove the screw securing the control
panel (if present) to the right side of the
unit, then remove it after electrical dis-
connection;
– remove the condensate tray (3) (not
present on FCX - B version);
– remove the coil cover sheet (4) by
removing the screws;
– remove the screws securing the coil (5),
then remove it;

installation, without control
panels).
to 50.
- 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 follows:
- 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 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
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 con-
nected to a grounded outlet.
The control panels consist simply of elec-
tric circuits connected to the mains volt-
age of 230V; all the inputs for the sen-
sors and controls must therefore be corre-
spondingly insulated for this voltage.
Some control panels are fitted with a room
temperature probe and/or a water tem-
perature probe. In addition, it is possi-
ble 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
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 mounting
in the coil to the delivery hose upstream
– remove the push-outs (6) on the right
side;
– rotate the coil (5), then secure it in the
new position with the screws previously
removed;
– remount the coil cover sheet (4) and
secure it with screws, then insert the
plastic plugs (7) supplied in the openings
left free by the hydraulic connections;
all trays are designed to collect conden-
sate on both sides. In the case of verti-
cal installation, for condensate drainage
on the right side, position the drainage
union to the right (8).

lation, with direct expansion
coil, without control panels).
condensate discharge pipe (supplied sepa-
rately) 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 con-
densate is discharged into the sewage sys-
tem, install a siphon to prevent return of
unpleasant odour into the room.
- Make the electrical connections as shown
in the wiring diagrams.
- Remount the cover, or the front pannel,
connect the ambient sensor or the micros-
witch (if present).
- CAUTION: Keep separate electrical con-
nections from water connections.
Water connections and drain should be on
the side opposite of the electrical connec-
tions.
of the valve.
When relocating the water tempera-
ture 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 con-
figuration, though can be adjusted to the
specific operating requirements by means
of the internal dip-switches.
Customised functions vary between mod-
els; for this reason, consult the relative
manuals.
WARNING: check whether the instal-
lation has been carried out correctly.
Follow the checking procedures indicated
in the manuals of the control panels.
– to move condensate drainage to the right
of the unit, reverse discharge of the tray
(3) (if present), then transfer the drainage
line (8) to the right;
– slide out the electrical connections from
the right side, remove the push-out, then
transfer the cable guide (9) from the right
to the left side;
– transfer the electrical connections to the
left side through the cable guide (9);
– move the terminal block (10) and the
ground jumper connection (11) to the
left side of the unit;
