FCL - FAN COIL
The FCL cassette-type fan coil:
4 sizes for 2-pipe systems
FCL 32 - FCL 36 - FCL 42 - FCL 62
4 sizes for 4-pipe systems
FCL 34 - FCL 38 - FCL 44 - FCL 64
VERSIONS
The cassette fan coils are available in three versions, to satisfy all system requirements.
The sizes, performance levels and outer dimensions are the same as those for the standard FCL
version.
In this manual, versions FCL_V and FCL_VL2 will only be referred to when there are differences
compared with the standard FCL version; otherwise they will simply be called FCL. Versions
FCL_V and FCL_VL2 are available upon request.
• Standard FCL version, with standard internal 3-way valve fitted with fast connection actuator
and visual signalling of the position.
• FCL_V2 version, with standard internal 2-way valve fitted with fast connection actuator and
visual signalling of the position, suitable for systems with a variable water flow rate.
• FCL_VL version, without an internal valve.
DESCRIPTION OF THE FCL CASSETTE-TYPE FAN COILS
The FCL cassette-type fan coil is a room air treatment terminal unit. The FCL concentrates high
technological and functional characteristics that make it the ideal climate control unit for all types of
rooms. The unit is installed in a suspended ceiling with the possibility to send conditioned air to
adjacent rooms and introduce external air regardless of unit ventilation. Thanks to its dimensions,
the FCL can be perfectly integrated in standard 600x600 suspended ceiling panelling.
The standard FCL unit is available in two versions, for 2-pipe and 4-pipe systems. The FCL
cassette-type fan coil is only complete when used with a grille of the GLL range - an obligatory
accessory for the operation of the fan coil. The grille accessory of the GLL range not only offers
delivery and suction with a filter, but also a special electric box with bayonet coupling to the
connector bound to the unit's load-bearing structure. The air filter is easy to remove and clean; it
has a self-supporting structure and is characterised by high efficiency and low pressure drops.
The same standard FCL unit can be configured in a number of versions by simply combining it with
3 different grille groups of the GLL range (obligatory accessories) that determine its working
modes.

- GLL 10 M: with remote control, louvres oriented by the remote control, IR receiver integrated in
the grille. GLL-M is complete with an electronic thermostat able to manage all the configurations
(heating coil with valve, cooling coil with valve, supplementary or replacement electric heater) as
well as all the functions (heating, cooling, continuous or thermostat-operated ventilation,
dehumidification, timed switch-on or switch-off operations). When working with the electric heater,
the ventilation is only active at maximum and medium speeds. The air filter can be regenerated
with a fire resistance class of V0 (UL 94). The grille is made of plastic, colour RAL 9010.
- GLL 10 R: with remote control, louvres oriented manually, IR receiver integrated in the grille.
GLL-R is complete with an electronic thermostat able to manage all the configurations (heating coil
with valve, cooling coil with valve, supplementary or replacement electric heater) as well as all the
functions (heating, cooling, continuous or thermostat-operated ventilation, dehumidification, timed
switch-on or switch-off operations). When working with the electric heater, the ventilation is only
active at maximum and medium speeds. The air filter can be regenerated with a fire resistance
class of V0 (UL 94). The grille is made of plastic, colour RAL 9010.
- GLL 10: version with louvres oriented manually, must be interfaced with an external control
panel, single or centralised (not included). The working modes are managed from the control
panel. It is necessary to choose a control panel that can manage all the functions and any
accessories that may be installed. The air filter can be regenerated with a fire resistance class of
V0 (UL 94). The grille is made of plastic, colour RAL 9010.
The load-bearing structure, reinforced with a galvanised steel side band, contains insulation
elements in expanded polystyrene obtained from injection moulding for purposes of noise
reduction and air routing.
The condensation drip tray is in one piece, with V0 self-extinguishing level and joined by means of
over-moulding technology to the insulation in expanded polystyrene with flame retardant additive.
The heat exchange coil has a shaped profile to increase the exchange surface.
In the standard version, the unit contains a 3-way valve with a fast connection actuator and visual
signalling of the position; there are also another two versions available, one with a 2-way valve and
the other with no valve. A second valve for 4-pipe systems is available as an accessory in the
versions for systems with fixed or variable flow rates.
The ventilation unit offers particularly quiet operation. It has 3 speeds for the smaller sizes (FCL
32-34-36-38) and 4 speeds for the larger sizes (FCL 42-44-62-64) so you can choose the 3 speeds
that best meet the individual needs of power supplied and quiet operation. The FCL can be set with
continuous fan operation to prevent the layering of room air.

Main customisations envisaged:
- electric heater for heating (accessories RXL and RXLE) - supplementary or replacement, they
can be installed in 2- or 4-pipe units
- 3-way valve for heating coils for 4-pipe systems (accessory VHL1)
- 2-way valve for heating coils for 4-pipe systems with variable water flow rate (accessory VHL2)
- connection flange for delivery air conduit towards a second nozzle, even in an adjacent room
(accessory KFL)
- connection flange for external fresh air conduit, even with the fan switched off (accessory KFLD)
- electrostatically pre-charged air filter, regenerated with class-2 fire resistance (UL 900),
(accessory).

DESCRIPTION OF THE COMPONENTS
Base
The unit is characterised by a
reinforced, integral metal structure
with insulation in expanded
polystyrene obtained from injection
moulding for purposes of noise
reduction and air routing. The load-
bearing base is in galvanised sheet
steel and is varnished with
polyester powders. The following
are fixed to the base: fixing
brackets, coils, motor and fan,
condensate discharge pump,
attachment plate, control board unit
and condensate drip basin. By
means of the flanges, it allows the
channels (for renewing
environmental air and/or delivery to
an adjacent room) to be joined to
the sides.

6
Basin
Thermal exchange battery
.
Basin closing off the unit.
Made of injection co-moulded
polystyrene to avoid thermal
dispersion and the formation
of condensate, it conveys
conditioned air towards the
louvres and from the
condensate drip basin. The
air intake conveyor is
equipped with a protective
grille that impedes access to
the moving fan.
The coils used have copper
pipes and corrugated or
turbulent aluminium louvres.
They are designed to offer
the maximum heat exchange
surface. All batteries are
provided with air bleed pipes
and water drain valves,
located respectively on the
highest and lowest point of
the battery circulation.

7
Three-way valve
Internal 3-way valve, of the
all-or-nothing type, with fast
connection actuator and
visual signalling of the
position, assembled as
standard on the
heating/cooling coil, powered
with a voltage of 230V ~
50Hz.

8
Fan unit
The fan unit, with the latest
axial-centrifugal fan designed
to obtain low sound
emissions, is dynamically and
statically balanced and
coupled with a 4-speed
motor. The fan unit can be
easily accessed for cleaning
and maintenance.
