3 UNIT DESCRIPTION
Fan coil unit with Design cabinet, minimum depth and BLDC motor. See gure p.60Exploded view.
DESIGNDRIVEN INNOVATION
From the extensive experience of Galletti in the development
and design of fan coil units, and in conrmation 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 eciency, while on the other
hand could, for the rst time, reect 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 eld 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 redened also in terms
of technical performance, thanks to the use of computational
uid dynamics simulations for the optimisation of the heat ex-
change inside the indoor unit combined with the use of perma-
nent magnet electric motors.

MAIN COMPONENTS
Cabinet
The elegant front panel consists of two sheets of aluminium
with a polyethylene core and possibly a polyester-based surface
coating. It is a light but very resistant material, created for cov-
ering façades in the building sector. The side panels are made of
UV-stabilized ABS to maintain the colour over time.
The polyethylene core acts as a exible ller and thermal in-
sulation while the aluminium provides structural strength and
aesthetics.
Conveyors
Made of high-density polystyrene. They are designed to opti-
mise the air ow inside the hydronic indoor unit allowing opti-
mal distribution of the air ow in the coil and low noise in every
operating mode.
Upper grille
Consisting of adjustable ns made of anodised aluminium, avail-
able in the version for on-board or wall-mounted control. The
ABS combs support the grilles and prevent them from being
bent, thus always guaranteeing the user’s safety.
Wall-mounted control unit version has a continuous upper grille.
In the version for on-board control, the grill has two side doors
to allow access to the control.
Front grille
Stabilizes the operation of the tangential fan unit and is
equipped with a stainless steel lter.
Electric motor
Permanent magnet BLDC motor with inverter integrated in
the ventilation unit. An IP54 protection rating is guaranteed;
therefore, dust inside is avoided and resistance to water spray
is guaranteed.
Heat exchangers
With high eciency turbocoil-type heat exchanger, and made
with copper tubing and aluminium ns, it is equipped with brass
manifolds and a vent valve.
The hydrophilic treatment is applied to the ns as a standard
treatment, to increase their eciency during cooling.
On standard version water connections are on the left. Water
connections on the right on request.
Air lter
Honey-comb polypropylene washable lter, easily removable
for maintenance operations.
Tangential fans
Tangential fan, statically and dynamically balanced to reduce its
noise during operation.
The ABS used for the blades guarantees, in comparison with
metal fans, a reduction in vibrations and an absence of bending
along the rotation axis.
The blades are alternated with intermediate reinforcement disks
in order to increase their sturdiness.

5 INSTALLATION
WARNING: unit installation and start-up must be entrusted
to competent personnel and performed in a workmanlike
manner, in accordance with current regulations.
For each unit an (IL) switch should be mounted on the power
supply, with opening contacts at a distance of at least 3 mm
and a suitable protection fuse (F) .
WARNING: Install the unit, circuit breaker (IL) and/or any re-
mote controls in a place out of reach of persons who may be
taking a bath or shower.
WARNING: the EMC lters connected to frequency con-
verters (inverters) can create leakage currents toward
ground (in order to make the unit EMC compliant, by re-
ducing conducted emissions on power supply line). De-
pending on installation site, this can force the cut out of the
dierential safety switch. It is recommended to install a sepa-
rate dierential safety switch, only for the BLDC unit, with an
adjustable threshold for the cut out current.
WARNING: base unit must be protect by original packaging
to avoid demage at the worksite, before cabinet installation.
WARNING: keep the cabinet inside the original packaging
until the nally installation
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 inammable gases or
powders are present
 Do not expose the unit to sprays of water
 Install the unit on walls able to withstand its weight. Keep a
clear space all around the unit to assure the proper function-
ing and accessibility for routine and extraordinary mainte-
nance (see gure 11.4Dimensionp.62)
 store the unit in its packing container until you are ready to
install it
INSTALLATION REQUIREMENTS
The fan coils should be installed in a position where the room
can be cooled or heated evenly, on walls able to withstand their
weight.
It is advisable to install any accessories on the standard unit pri-
or to positioning the latter.
For installation and use of accessories, please refer to the relative
technical sheets.
Install any remote control panel in an easily accessible position
allowing the user to set the functions while ensuring an accurate
reading of the ambient temperature, if provided.
Avoid therefore:
 positions directly exposed to sunlight;
 positions exposed to direct currents of warm or cold air
 placing obstacles that impede an accurate temperature
reading
The water connections are on the left side, viewing the unit
from the front.
Hydraulic connections on the opposite side are available on-
ly on order
The water connection pipes must pass through the slots pro-
vided on the rear panel of the unit (depending on the L or R
version, use the appropriate slot)
NOTE: the electrical wiring must always be positioned on the
opposite side of the plumbing connections.
Make the plumbing connections to the heat exchanger and,
where the cooling function is to be used, to the condensate
drainage outlet.
It is recommended to connect the installation intake to the up-
per part of the heat exchanger and the return to the bottom part
of it.
Bleed air from the exchanger by means of the air vent valves
(hexagonal wrench type 10) situated beside the plumbing con-
nections of the exchanger. See gure p.63Air vent.
To favour the drainage of condensate, the drain hose should be
inclined downward, at least 3 cm/m; make sure that no loops or
bends form along its path.
WARNING:
In normal operation, particularly with the fan at minimum
speed and ambient air with high relative humidity, conden-
sation may form on the air outlet and on some external parts
of the unit.
To avoid such issues while always remaining within the op-
erating limits envisaged for the unit, it is necessary to limit
the (average) temperature of the water inside the heat ex-
changer. In particular, the dierence between the air dew
point (TA,DP) and the average water temperature (TWM) must
NOT exceed 14 °C, according to the following relationship:
TW>TA,DP-14 °C
Example: in the case of ambient air at 25 ° C with 75% rel-
ative humidity, the dew point temperature is about 20 ° C
and therefore the average temperature of the water in the
battery must be greater then:
 20-14 = 6 °C in order to avoid condensation on a fancoil
equipped with a valve.
 20-12 = 8 °C If the valve kit accessory can not be installed.

In the event the indoor unit is stopped for a prolonged peri-
od, with the fan stopped and circulation of cold water in the
heat exchanger, condensation may also form on the unit’s
exterior. In this case it is advisable to install the 3-way (or
2-way) valve accessory in order to stop the ow of water in
the coil when the fan is stopped.
During wintertime periods of quiescence, drain water from the

FC66005296 21
system, to prevent ice from forming. If anti-freeze solutions are
used, check for their freezing point using the table below.

MOUNTING BASE UNIT AND COVER CABINET
Upon receipt of the unit, check the integrity of the package.
Leave the cabinet inside the packaging and proceed with the
installation of the base unit (which also includes the air outlet
grille, in the upper part) to the wall using the 4 slots provided
and the screw anchors suitable for the characteristics of the sup-
porting wall, keeping the bottom edge at least 100 mm above
the oor to ensure a correct intake of air and facilitate the lter
removal. See gure p.68 Air lter.
Once the installation of the base unit (which also includes the
hydraulic and electrical connections) is completed, it is possible
to proceed with the assembly of the covering cabinet (front pan-
el and side panels)
In order to x the cabinet, proceed with positioning it near the
base unit, so as to align the support pins with the slots on the
rear panel (see gure 11.11Cabinetp.69).
Then, lower the cabinet so as to obtain the locking of the pins
inside the appropriate seats.
To prevent the cabinet from disassembling it is necessary
to act on the lower locking screw, as shown in the gure
11.11Cabinetp.69.
6 CHECKS BEFORE STARTUP

8 MAINTENANCE
For safety reasons, before carrying out any maintenance or
cleaning jobs, turn o the unit by moving the fan speed se-
lector to “O” and putting o the main switch (0 position).
Due caution must be taken while carrying out maintenance:
some metal parts may cause injuries; wear protective gloves.
ART-U type fan coils do not have particular maintenance re-
quirements: it is sucient to periodically clean the air lter.
A running in period of 100 hours is necessary to eliminate all ini-
tial mechanical friction of the motor.
Start-up should be carried out at the maximum operating speed.
To assure that the ART-U fan coil units perform eciently, abide
by the following indications:
 keep the air lter clean
 do not pour liquids inside the equipment;
 do not introduce metal parts through the air outlet (upper)
grill and through the frontal grill;
 avoid obstructing the air outlet or intake
Whenever starting up the unit after it has not been used for a
long time, check that there is no air in the heat exchanger.
Before the period of operation in the cooling mode, check that
condensate is properly drained and that the heat exchanger ns
are not obstructed by impurities.
Clean as necessary using compressed air or low pressure steam,
taking care not to damage the ns.
Adequate periodic maintenance will ensure save both ener-
gy and cost savings.
CLEANING THE AIR FILTER
Clean the air lter at least once a month and in any case at the
start of the period of use (before the heating and the air condi-
tioning season).
To clean the air lter proceed as follows see gure  p. 68 Air
lter:
1. Unscrew the two M5 screws that block the lter by pulling
it out of its housing and freeing it from the magnets (use a
Phillips screwdriver, maximum length 8 cm).
2. Clean it with warm water (in the event of dry dust build-up,
using compressed air).
3. After allowing it to dry, t the lter back in place.
4. Once the lter has been repositioned, x it again with the
two M5 screws.
WARNING: THE FILTER MUST ALWAYS BE SECURED IN PLACE
WITH THE SCREWS PROVIDED TO PREVENT ACCIDENTAL
CONTACT WITH THE FAN.
It is recommended to replace the air lter once a year, using an
original replacement lter; the indoor unit model is specied on
the identication plate on the inside of the side panel.
CLEANING THE HEAT EXCHANGER
It is advisable to check the condition of the exchangers before the start of every period of use and to make sure that the ns are not
obstructed by dirt.
CLEANING THE CABINET
 Use a soft cloth
 Never pour liquids onto the unit, as this could cause electri-
cal discharges and damage the internal components.
 Never use harsh chemical solvents.
