AREO ACP
All single-phase MODELS are supplied with a single speed motor all
motors are fitted with an internal safety thermal cut-out (klixon), class
F windings, protection rating IP 54.
- Axial fan with statically balanced sickle blades housed in a specially
designed compartment that enhances ventilation and reduces noise
emissions.
- Safety grille made of electrogalvanized steel wire: it supports the
motor and is fixed to the cabinet by means of vibration-damping
GB
supports.
Main components as shown in figure 2:
(1) Cabinet: side panel
(2) Cabinet: upper/lower panel
(3) Rear panel/fan compartment
(4) Finned block heat exchanger (heat exchanger coil)
(5 ) Safety grille (fan) supporting motor
(6) Adjustable louvers
(7) Top cover of heat exchanger
(8) Conveyor duct
(9) Wall/ceiling mounting brackets
(10) Plastic corner trim on cabinet

(2) Water outlet connection, male gas coupling
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,
according to the number of motor poles and type of air flow of the unit.
The maximum installation height is shown in figure 4.
All models making up the AREO ACP 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.
Using suitable lifting equipment (a forklift truck is recommended), convey
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
inside the heat exchanger.
Warning: for hydraulic connections use a tightening
wrench to avoid the manifold rotation that may damage
the heat exchanger (figure 7)
If the unit is to be ceiling mounted (for vertical air flow), make sure it is
installed in a perfectly level position.

6 WIRING
The standard motors installed in AREO fan heaters are of the closed type:
asynchronous three-phase 2-speed motors (400/400 V Y connection )
or single-phase single-speed motors.
400/400 V -Y motors are equipped internally with klixon and speeds are
selected by means of a normal star-delta switch (accessory CST), figure
15.
The terminals of the klixon are connected to the terminal block so that they
can be used as protection in series with the coil of a contactor (TOP in the
terminal block, figures 9, 10, 11).
If the internal klixon is not used to protect the motor, it will be necessary
to provide a motor overload cut-out set at a current that is 10-15% higher
than the current indicated on the unit rating plate.
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
omnipolar mains disconnecting switch pole in overvoltage
category III.
The table in figure 8 shows the electrical specifications of the motors,

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.

FUNCTIONAL TEST

- 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.
- 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 14).
