Carefully read this handbook
1 BEFORE INSTALLING THE EQUIPMENT
Read this manual carefully.
The equipment is to be installed and serviced exclusively by technical personnel who
are qualified for using this type of machine, conforming to the prevailing regulations.
On receiving the equipment, check its state ensuring that it was not damaged during
transport. Refer to the associated technical sheets for the installation and use
instructions of any accessories.
2 INTENDED CONDITIONS OF USE AND OPERATING LIMITS
No responsibility is assumed by Galletti S.p.A. if the equipment is installed by
unqualified personnel, if it is used improperly or under inadmissible conditions,
if maintenance is not performed as envisaged in this manual or if original spare

Keep the equipment inside the packing until it is ready to be installed so that dust
will not infiltrate.
Air sucked by the equipment must always be filtered. Use, when possible, the specific
accessories (MA/F, MA/FO).
If not used during the winter, drain the water from the system to prevent damage
caused by the formation of ice. If antifreeze solutions are used, check the freezing
point.
Do not change the internal wiring or other parts of the equipment.

DESCRIPTION OF THE EQUIPMENT

The UTN range of air conditioning and hot-air heating units has been implemented for
conditioning rooms that require the installation of channeled units.
The main components are as follows:

Load-bearing structure made of galvanized steel sheet of suitable thickness,
duly insulated with noise-proof/anticondensing material, self-extinguishing in
Class 1. Complete with inspection panels, air delivery panel with round collars
(Ø 200 mm), setup for external air inlet and fast-coupling slots.

Heating fan unit with single or dual fan wheel, dual intake centrifugal type,
with statically and dynamically balanced impellers, coupled directly to the 3-
speed electric motor, equipped with permanently fit condenser and thermal
safety device.

Terminal strip for fast-on electrical connection;

Heat exchanger: high-efficiency, made of copper tube and aluminium fins
secured to the tubes by mechanical expansion. They are fit with brass manifolds
and air valves. The heat exchanger, normally supplied with left-hand attachments,
may be turned 180°.

System for collecting and discharging condensate setup either for ceiling or
wall mounting. All UTN range models may be installed either in horizontal or
vertical position.

5 INSTALLATION
On the thermal-ventilating unit install a switch (IL) and/or all remote controls
in a position out of the reach of persons who are in a bathtub or shower.
The UTN air conditioning and hot-air heating units may be installed either in
horizontal or vertical position. Check that the desired installation complies with
one of the diagrams shown in FIGURE 8, in which both possible configurations,
AA or AB, are suitable to work for heating and cooling.

AA (INTAKE IN LINE – DELIVERY IN LINE):
AB (AIR SUCTION AT 90° - AIR OUTLET IN LINE):
- CONFIGURATION of the unit
The units are always supplied in AA configuration, but the air intake position
may be changed during the installation.
If the installation differs from the supply terms, the layout must be changed by
dismantling the unit as shown in FIG. 9;
Note: closing panels, connection panels to channels or round ducts, filter module
(parts 1, 2, 3, 4) and other like accessories, are mounted as shown in FIG. 9by adjusting
the fastening screws.
