1 MAIN FEATURES
FLAT by Galletti represents a new generation of fan coil units and has been
engineered to offer performance and design features placing it at the top of its
category.
FLAT means innovation also in terms of engineering: it combines a guarantee
of excellent low-noise performance with the advantage of an exclusive design
that fits well with both residential and commercial settings.
The construction concept allows to standardize the models for vertical
mounting and those for horizontal mounting: 2 versions for floor wall or
ceiling installation:
FLAT L Wall mounted installation with decorative cabinet with vertical air
outlet.
FLAT U Floor / ceiling installation with decorative cabinet vertical air
outlet and suction grille complete with filters.
The uniqueness of FLAT lies both in the use of extremely high quality materials
- which contribute to making this product exceptionally robust - and the
assurance of constant performance over time.
OPERATING LIMITS
> thermal fluid: water
> water temperature: from 5°C to 85°C
> maximum operating temperature: 10 bar
> air temperature: from 5°C to 43 °C
> power supply: 230V +/- 10%
The technical and dimensional data reported in this manual may be modified in view
of any product improvement

2 VERSIONS AND MAIN COMPONENTS
> DESIGN CASING
Colour RAL9010
Front panel made of sheet steel
Side panels upper grill and side doors manufactured from UV-stabilised
ABS to maintain the colour intact over time.
The upper grille is made of a FLAP and by swinging fins to adress the
flow to the outdoor ambient on the right and on the left.
The flap features a microswitch that automatically shuts down the unit
(fan motor and valves) when the flap itself is closed.
The closing of the FLAP avoids the risk of dust inside the machine
when the unit is not used.
The side doors provide access to the control panel and compartment
housing the plumbing connections.
The doors may be secured by screws to prevent opening.
> BEARING STRUCTURE
Made of thick galvanized steel sheet insulated withself-extinguishing
Class 1 heat-insulating panels.
FLAT U can be used both for vertical installation (on the floor) and for
horizontal installation by means of two different trays for collecting and
discharging the condensate of the heat exchanger.
The basic unit is presetted for assembling all the available accessories
on "FLAT" product line.
> FAN MOTOR ASSEMBLY
Thanks to the new fan-drive assembly FLAT ranks at the top of the category
of indoor air-conditioning units in terms of low-noise operation.
The fan motor assembly Includes 1 ore 2 centrifugal fans with staggered
airfoil-shaped blades manufactured from anti-static ABS (To avoid the
dust and the consequent unbalance).
The fans are housed in a low-noise ABS volute distinguished by a
compact high-efficiency profile.
The 3-speed electric motor is directly coupled to the centrifugal and
installed on vibration-damping supports; it comes complete with built-in
capacitor and thermal protection for the windings.
Six speed motor available on request.
> HEAT EXCHANGER
High-efficiency heat exchanger made of copper pipe and aluminium fins
fixed to the pipes by means o mechanical expansion equipped with
brass manifoldsand air purge valve.
The units normally come with water connection on left side butthe heat
exchanger and can be turned on the field by 180°.
On request it is possible to install an additional 1 row heat exchanger for
the connections to the hot water circuit in 4 pipe system.
>AIR FILTER
Washable air filter made of beehive polypropylene installed on galvanized
sheet frame with safety grille easy to remove for maintenance.
The filter may be secured to the unit by means of screws.
in the U version the air filters are inserted in the intake grilles on the front
panel of the cover cabinet.
The innovative BIOXIGEN system applicable on all units guarantees high
standards of quality and purification of interior air as well as of the fan coil
unit itself.
> CONTROL PANELS
New control panels for controlling and regulating the temperature by means
of a microprocessor-based system which adapts the operation of the fan
coil automatically when room conditions change.
FLAT fan coils units can be connected to ERGO network.

Galletti indoor units is completed by the LED503
command with LED display that is designed for
recess wall mounting.
CONTROLLER
The control software developed by the Galletti Software Dept. features:
- Manual fan speed selection;
- Automatic selection of fan speed according to the difference between
the set temperature and the room air temperature;
- Manual selection of heating/cooling operating mode;
- Automatic selection of heating/cooling operating mode;
- Control of 1 or 2 ON/OFF valves;
- Control of additional heating element;
- On board timer function to detect the actual ambient temperature;
- Reading of air ambient temperature set point fan speed and mode
selection on the LED display.
S - ater temperature sensor for microprocessor controls
model MYCOMFORT and LED503
Connected directly to the microprocessor control panel this probe
measures the water temperature inside the heat exchanger.
If the temperature registered is lower than 17°C the unit works in
cooling mode and the temperature range of the control panel will
be referred to the cooling mode (19 / 31°C); if the temperature
registered is higher than 37°C the unit works in heating mode and the temperature
range of the control panel will be referred to the heating mode (14 / 26°C).
If the temperature registered is between 17°C e 37°C the control panel will
disable the unit operation.

9 INSTALLATION SUGGESTIONS
Fan coil units should be installed in a position where they heat and cool the room
evenly on walls or ceilings that can bear their weight.
Fit any accessories on the standard unit before installing it.
Read the relevant technical sheets for the installation and use of the accessories.
Keep free space around the fan coil to allow proper operation and ordinary and
extraordinary maintenance (see the overall dimensions chapter)
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 following table
.
Glycol percentage Freezing Capacity correction Pressure drop
in weight temperature (°C factor correction factor
0 0 1,00 1,00
10 -4 0,97 1,05
20 -10 0,92 1,10
30 -16 0,87 1 15
40 -24 0,82 1,20
1 MAINTENANCE
FLAT fan coils do not require special maintenance: it is enough to clean the
air filter periodically.
The motor does not need maintenance as it is fitted with self-lubricating
bearings.
Replace the air filter once a year using original spare parts; the fan coil model
can be seen on the ID plate on the internal side-panel.
Refer to the installation use and maintenance manual supplied with the
product for all cleaning and maintenance operations.
