1  BEFORE STARTING THE INSTALLATION PROCEDURE

Carefully read this manual.
Installation and maintenance should be carried out by technical 
personnel qualified for this type of machine, in compliance with 
current safety regulations.
When receiving the unit please check its state verifying if any 
damage occurred during the transport.
For installation and use of possible accessories please refer to 
the pertinent technical sheets.
Identify the model of the ART-U fan coil following the indications 
on the packing container. See paragraph   Configurator  p. 19.

WARNING:

 Electrical and electronic products may not be 

mixed with unsorted household waste. Do NOT try to dis-
mantle the system yourself: the dismantling of the system, 
treatment of the refrigerant, of oil and of other parts must be 
done by an authorized installer and must comply with appli-
cable legislation. Units must be treated at a specialized treat-
ment facility for reuse, recycling and recovery. By ensuring 
this product is disposed of correctly, you will help to prevent 
potential negative consequences for the environment and 
human health. For more information, contact your installer 
or local authority.

2 INTENDED 

USE

Galletti S.p.A. will not accept any liability for damage or injury 
caused as a result of installation by non-qualified personnel; im-
proper use or use in conditions not allowed by the manufactur-
er; failure to perform the maintenance prescribed in this manual; 

use of spare parts other than original factory parts.
Equipment designed for ambient air conditioning and intended 
for use in civil comfort applications.

INSTALLATION SITE

When choosing an installation site, you should observe the fol-
lowing rules:

 

—  The air conditioning unit should not be placed immediately 

under a socket 

 

—  Do not install the unit in places where inflammable gases or 

powders are present

 

—  Do not expose the unit to sprays of water

 

—  Install the fan coil on walls able to withstand its weight. Keep 

a clear space all around the unit to assure the proper func-
tioning and accessibility for maintenance

 

—   Store the unit in its packing container until you are ready to 

install it to prevent dust from infiltrating inside it.

DESIGN-DRIVEN INNOVATION

From the extensive experience of Galletti in the development 
and design of fan coil units, and in confirmation of its continu-
ous search for innovation, has been created ART-U, the result of 
a perfect combination of performance and design.
The ambitious goal of this project was to develop something 
absolutely new and unique, a product not yet present on the 
market, which on the one hand was able to meet the increasing-
ly stringent demands for energy efficiency, while on the other 
hand could, for the first time, reflect the latest trends in furnish-
ings and interior design.
With the new ART-U, Galletti this goal has been fully achieved, 
presenting on the market a new concept of hydronic indoor 
unit, a product that is characterized by its enviable technical 
performance and at the same time represents a true style shift 
in a field that has long been dominated by products that are all 
very similar to each other.
ART-U, with its width that in some places is only 10 cm, and 
thanks to its unique lines, was designed to be an absolutely 

all-purpose product, that adapts perfectly to rigorous and es-
sential environments as well as to warmer and more sophisticat-
ed spaces. Thanks also to the possibility of customizing the front 
panel, ART-U meets the demand for ever more personalization 
of the spaces to be furnished.
The achievement of extremely high aesthetic standards has not 
weakened the usual construction integrity of Galletti products: 
striving for innovation has in fact also focused on the compo-
nents and the use of new materials.
With ART-U the state of the art has been redefined also in terms 
of technical performance, thanks to the use of computational 
fluid dynamics simulations for the optimisation of the heat ex-
change inside the indoor unit combined with the use of perma-
nent magnet electric motors.
