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:
- In the case of floor-mounted units on bases, refer to the instructions
supplied with the accessory.
- 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 AMPZ 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 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 "drawings - fig.6")
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 person-
nel 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 conditions.
Stranded wires may only be used in connection 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/113°F (<85% U.R.).
The control panel may not be fitted on a metal wall unless this is per-
manently connected to a grounded outlet.
The control panels consist simply of electric circuits connected to
the mains voltage of 120V; all the inputs for the sensors and controls
must therefore be correspondingly insulated for this voltage.
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 (chapter "drawings -
fig.8-9") :
– remove the condensate tray (a)
- Remove the battery cover (B) by loosening the screws;
- Remove the screws that secure the battery (c) and then pull it out;
- Rotate the coil (c) and fix it with the screws previously removed;
- Replace the cover (b), securing it with the screws and the plastic caps
(s), supplied together, the holes left by the hydraulic connections;
all the trays are arranged for the condensate discharge on both sides.
- Slide out the electrical connections from the right side, remove the

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 cooling appli-
cations.
For a correct tightening of the hydraulic fittings during the installa-
tion it is necessary to use 10 teflon turns and a maximum torque of
14 Nm (chapter "drawings - fig.5")
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(chapter "drawings - fig.7") .
The condensate drainage system should be of an adequate size and
be positioned to favour runoff (min. 1% slope). If condensate is dis-
charged 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 connec-
tions.
Water connections and drain should be on the side opposite of the
electrical connections.
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 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/102 °F.
In installations with a three-way valve, the minimum water tempera-
ture probe must be relocated 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
suitable length.
CAUTION: given that it is powered to 230 VAC, the probe has
double insulation.
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.
The connections are made by the manufacturer as shown in the pic-
ture (chapter "drawings - fig.7") .
WARNING: check whether the installation has been carried out
correctly. Follow the checking procedures indicated in the manu-
als of the control panels.
push and move the cable guide (g) from right to left;
- Transfer the electrical connections on the left side through the cable
guide (g);
- Move the terminal (h) and the jumper of the ground (s) on the left
side.
