DECLARATION OF CONFORMITY
Galletti S.p.A. whose main office is located at 12/a via Romagnoli,
40010 Bentivoglio (BO) - Italy, hereby declares, under its own
responsibility, that the fan heaters belonging to the AREO series,
indoor units for air-conditioning systems, conform to the
specifications of
98/37/CE, 2004/108/CE, 2006/95/CE
and subsequent
modifications.

BEFORE STARTING INSTALLATION
Carefully read this manual.
Installation and maintenance may be carried out solely by qualified
technicians specifically trained for this type of equipment, in conformity
with current regulations.
On receiving the equipment, check that it has not undergone any damage
during transport.

INTENDED USE AND OPERATING LIMITS
Galletti S.p.A. will not accept any liability for damage or injury caused as
a result of:
- installation by non-qualified personnel;
- improper use or use in conditions not allowed by the manufacturer;
- failure to perform the maintenance prescribed in this manual;
- use of spare parts other than original factory parts.
The operating limits are specified at the end of this chapter; usage outside
the stated limits is to be considered improper.
When choosing an installation site, you should observe the following rules:
- The heating unit should not be placed immediately under a socket.
- do not install the unit in places where inflammable gases are present;
- do not expose the unit directly to sprays of water;
- install the unit on walls or ceilings able to withstand its weight; use
accessories suited to the purpose and suitable screw anchors.
Store the unit in its packing container until you are ready to install it to
prevent dust from infiltrating inside it.
Installation, maintenance and cleaning jobs may be carried
out only with the power supply disconnected.
If the unit is installed in a room that is only occasionally used, the
temperature in the room itself must be kept above 0°C or else antifreeze
must be added to the water to prevent it from freezing inside the coil.
Do not attempt to modify the internal wiring or other parts of the unit.
Operating limits
- Thermal carrier fluid:
water
- Water temperature:
min + 7°C, max +95°C
- Air temperature:
min -10°C, max + 40°C
- Supply voltage:
rated v/- 10%
- Max water pressure during operation:
10 bars
To prevent phenomena of condensate dripping, it is advisable
to select indoor units capable of maintaining, when operating at
full capacity, an air temperature below 35 °C and relative humidity
of less than 60%.
The range comprises 18 models whose features are summarised in the
table of figure 1 where:

UNIT DESCRIPTION
AREO is an indoor unit for heating medium to large interiors with a horizontal
discharge of warm air. It comprises the following main components:
-
A pre-painted sheet steel cabinet
complete with ABS corner trim,
internally insulated to prevent condensate from forming on the cabinet
during operation with chilled water.
The cabinet is complete with adjustable aluminium louvers (spring-
operated) placed on the air outlet which enable an optimal distribution
of air within the room.
On the rear of the cabinet there are
4 brackets for suspending the
fan heater
from the ceiling or joining it to the mounting board for
installation on the wall (accessory DFC, DFP or DFO).
-
Heat exchanger
, made up of copper tubing and aluminium fins
providing superior thermal conductivity compared to traditional iron pipe
exchangers.
The heat exchanger is set back in relation to the air outlet; an
auxiliary
drip tray
is fitted onto the front to guarantee complete collection of
condensate.
- Galvanised sheet steel
drip tray
insulated with closed-cell polyurethane,
connected to the auxiliary tray.
-
Electric motors:
two-speed, 4/6-pole or 6/8-pole, in 400V three-phase delta-triangle
configuration.
ALL MODELS may be supplied with a single-phase motor with three
speeds corresponding to 4/6/8 poles for sizes from 1 to 4 and 6/8/10
poles for sizes 5 and 6.
All motors are fitted with an internal safety thermal cutout, class F
windings, protection rating IP 55.
-
Axial fan
with statically balanced sickle blades housed in a specially
designed compartment that enhances ventilation and reduces noise
emissions.
-
Safety grille
made of electrogalvanised steel wire: it supports the motor
and is fixed to the cabinet by means of vibration-damping supports.
