DECLARATION OF CONFORMITY
Galletti S.p.A. with head offices in Via Romagnoli 12/A, 40100
Bentivoglio (Bologna) - Italy, declares under its own exclusive
responsibility that the UTN range of air conditioning and hot-air
heating units, heating and conditioning equipment, for systems
that distribute air through channels, comply with the requirements
of the following EEC Directives:
73/23, 89/392, 91/368, 93/44, 93/68, 98/37 and 89/336.
Bologna, 02/07/2001

Chairman
OPERATING LIMITS
Thermal carrier: water
Water temperature: + 5°C to +95°C
Air temperature: -20°C to + 43°C
Power supply voltage: 230 V +/-10 %
Max. pressure of primary fluid: 10 bar
1 MEAN FEATURES
The new range of UTN high pressure fan coils units has been designed for
conditioning rooms that require the installation of ducted units.
Proposed in 12 models with air flows from 600 to 3000 m3/h, the UTN units
are characterized by a wide applicative flexibility thanks to the special
constructive solutions.
> possibility of installation both in horizontal and vertical position thanks
to the special conformation of the condensate discharge system;
> the air intake direction may be modified during installation;
> reduced height (280 mm up to model 16A);
> pre-shared element for the recycle of external air, standard on all models
(Φ 100 mm);
> wide range of accessories for effectively.
2 VERSIONS AND COMPONENTS
Versions
UTN air handling unit setup for 2-pipe systems
UTNDF air handli ng unit set up for 4-pipe systems (2 heat
exchangers)
N.B. both version may be manufactured, on request, with pre-painted
panels.
Components
> Load-bearing structure made of galvanized steel sheet of suitable
thickness, duly insulated with noise-proof/anticondensing material,
self-estinguishing in Class 1; the insulating material is characterized
by a thickness of 10 mm and a density of 90 Kg/m3.
The unit is completed by the following:
- inspections panels;
- setup for external air intake;
- fast-coupling slots.
> Dual intake centrifugal fans made of alluminium, with statically and
dinamically balanced impellers, coupled directly to the electric
motor.
> 3 speed electric motor, equipped with permanently fit condenser and
thermal safety device, installed on vibrator damping supports.
> Heat exchanger: high efficiency, made of copper tube and alluminium
fins secured to the tubes by mechanical expansion. It is fitted with
brass manifolds and air valves. The heat exchanger, normally
supplied with left hand attachments, may be turned by 180°.
> System for collecting and discharging condensate setup either for
horizontal or vertical installation.
> Terminal strip for fast - on electrical connections.
The technical and dimensional data indicated in this catalougue are subject to modifications
in the view of the improvement of the product.

8 INSTALLATION SUGGESTIONS
UTN units can be installed both vertically and horizzontally.
The UTN units are always supplied for the A-A placing.
If a different placing is needed the installer can modify it before mounting the
unit (see chapter 3 "POSSIBLE CONFIGURATIONS").
Choose the unit position to have the best ductwork path.
The air sucted by the unit must be filtered: use the MAF or MAFO accessories.
Fit any accessories on the standard unit before installing it.
It is suggested to use anti-vibration joint (available as option) between the
unit and the ducts.
Ductworks, in particular the air outlet one, must be insulated to avoid
moisture formation.
Glycol percentage in weight Freez ing temperature (°C) Capacity correct ion factor Pressure drop correction factor

20 -10 0,92 1,10
30 -16 0,87 0,05
40 -24 0,82 1,20
Keep free space around the fan coil to allow proper operation of the unit and
ordinary and extraordinary maintenance.
Install the remote control panel, if any, in a position that can easily be reached
by the user to set the functions and that is suitable for the proper detection
of the temperature, if provided.
Therefore avoid:
- positions directly exposed to sunlight;
- positions exposed to hot or cold draughts;
- obstacles preventing the proper temperature detection.
If the system is shut down during the winter months, drain off the water from
the system to prevent damage due to freezing; if antifreeze solutions are
used, check the freezing point using the table shown at the foot of the page.

13 MAINTENANCE
The maintenance operations for the UTN air conditioning and hot-air heating
units are limited to the periodic cleaning of the air filter (provided on MA/F and
MA/FO accessories) and the heat exchanger, and the checking of the working
efficiency of the condensate discharge.
Only skilled personnel may perform the aforesaid maintenance.
Pay utmost attention during the maintenance operations: accidentally
coming into touch with some of the metallic parts might cause injuries
therefore wear safety work gloves.
Every time the units are started after long dwell times, make sure that air is
NOT present inside the heat exchanger.
The motor is maintenance-free since it is equipped with self-lubricating
bearings.
For safety reasons, before performing any maintenance or cleaning
operations, turn off the equipment and cut voltage by turning the line
switch.
