5 INSTALLATION
Remove the fan heater from the packing container and check that no
damage has occurred during transport.
Before starting to install the unit, make sure that the installation height and
air range conform to the specifications provided in the technical catalogue.
The maximum installation height is shown in figure 4.
All models making up the AREO C series can be mounted either on a wall
(heating function) or on the ceiling (heating function ONLy).
In the case of wall installation, use suitable mounting boards, available
as accessories:
DFP for wall mounting
DFC for mounting on columns
Adjustable DFO for mounting on walls/columns (from 0° to ±45°).
If you do not use the mounting boards supplied by the manufacturer, make
sure in any case that the unit is adequately spaced from the wall or ceiling,
at a distance that is at least that shown in figure 5.
Use screw anchors of adequate dimensions to support the weight of the
unit and make sure that the surface of the installation site is suited to the
purpose.
For ceiling installation, use the 4 brackets provided and suspend the fan
heater with 4 suitable chains, bearing in mind its weight.
To optimise the distribution of air within the room, half of the louvers
should be turned 180° as indicated in figure 6, by pressing on the louver
to compress the spring.
Use suitable lifting equipment to move the unit to the installation site and
rest it on the side of the fins.
The plumbing connections on the side of the unit may not be used to carry
or bear the weight of the unit.
The unit must be installed perfectly level to prevent air pockets from forming
within the heat exchange coil, and in the case of operation in the cooling
phase, to ensure proper drainage of the condensate.
Warning: for hydraulic connections use a tightening wrench to avoid
the manifold rotation that may damage the heat exchanger (figure 7)
When used in air conditioning mode there should be an adequately sized
condensate drain line (with sufficient inclination), ensuring its operation
is tested before starting the unit.
In order to prevent dragging condensate phenomena use the
AREO C fan heaters in the cooling phase only at the maximum
speeds permitted for each model. The maximum permitted speed
for each model is indicated by the symbol
regulator supplied with the unit (mandatory accessory) The maxi-
mum permitted speed for each model may be

Warning: cooling operation is ONLY allowed for WALL-MOUNTED
units
The water inlet must be placed in correspondence with the lower fitting,
in order to have improved air ventilation inside the coil and a correct
functioning of the heat exchanger.
If the unit is to be ceiling mounted (for vertical air flow), make sure it is
installed in a perfectly level position.
On completing installation, open and direct the louvers.

The standard motors used on the AREO C fan heater series consist of
two permanent magnets with built-in inverter.
THERE IS NO NEED FOR AN EXTERNAL THERMAL PROTECTION,
THE ENGINE HOWEVER REQUIRES PROTECTION OF ITS POWER
SUPPLy LINE.
Make the electrical connections with the power supply disconnected, in
accordance with current safety regulations. All wiring must be carried out
by qualified personnel.
Check that the mains electricity supply is compatible with the voltage
shown on the unit rating plate.
Scrupulously follow the wiring diagram provided, according to the type
of installation.
Each fan heater on the supply line must be equipped with an omni-
polar mains disconnecting switch pole in overvoltage category III.

If single-phase fan heaters are installed on a three-phase line, they
must be connected so as to ensure an equal distribution over the 3
phases: this will ensure a balanced load.

- Check the tightness of the plumbing connections.
- Check the stability of the mounting brackets if the unit is installed on
the wall; the chains if the unit is ceiling mounted.
on the RVM speed
- Make sure that the wiring is firmly secured.
- Make sure that air has been eliminated from the heat exchanger.
- Adjust the louvers as desired and switch on the unit to check that it
works properly.
- Always make sure that the fan turns in the correct direction (ANTI-
CLOCKWISE viewing the fan heater from the rear, figure 11).
