IFCLTY 1112 - 4528511_04
sheet steel, thermally insulated with
closed cell polyethylene foam and cov-
ered with anti-condensate felt.
FASTENING BRACKETS
Galvanised steel brackets for attaching
the unit to the ceiling.
TRAY
Tray closing off the unit. Made of injec-
tion co-moulded polystyrene to avoid
thermal dispersion and the formation of
condensate, it conveys conditioned air
towards the louvres and from the con-
densate drip tray.
The air suction conveyor is equipped
with a protective grille that impedes
access to the moving fan.
THERMAL EXCHANGE COIL
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.
WATER VALVE
The standard version of the unit includes
an internal 3-way all-or-nothing valve
with fast connection actuator and
visual position signalling, assembled
as standard on the heat/cool coil and
powered with a current of 230V ~
50Hz.
The units are available - upon request -
in two other versions, one with a 2-way
valve and the other without a valve.
The units with dual coil (for 4-pipe sys-
tems) can be connected to a second
valve, available as an accessory in the
3-way versions (for fixed output sys-
tems), or the 2-way versions (for vari-
able output systems).
FAN UNIT
The fan unit, with the latest axial-centrif-
ugal fan designed to obtain low-sound
emissions, is dynamically and statically
balanced.
The electric motor offers 3 speeds for
smaller sizes (FCL 32-34-36-38) and
4 speeds for larger sizes (to be able
to select the 3 speeds that best meet
the specific power and noise require-
ments). The FCL can be set with con-
tinuous fan operation to prevent the
layering of air in the room.
The electric motor is cushioned with
elastic supports and the steel shaft is
assembled on bearings.
The fan unit can be easily accessed for
cleaning and maintenance.
CONDENSATE DISCHARGE DEVICE
The condensate drain device is needed
to dispose of the condensate that is
produced by the unit and deposited in
the polystyrene tray. The device con-
sists of a control card, a non-return
valve, a three-level floating sensor
and a pump with a maximum head of
800mm. The unit can easily be con-
nected to the condensate discharge sys-
tem by means of a plastic coupling
(ext. Ø 16mm).
ALARM: when the level of condensate
in the tray reaches the prefixed limit,
the alarm will stop the flow of water
to the battery, allowing only the fan to
function.
WATER CONNECTIONS
The attachment plate groups together
the water connections and the vent
of the coil's primary circuit for 2-pipe
and 4-pipe systems. The plates contain
raised symbols that identify the input
(IN) and output (OUT) water connec-
tions for the water.
FILTERING SECTION
The air filter is inserted in the suction
grille.
Mechanical air filter with ABS frame.
Filter in filtering class G1, self-
extinguishing class V0 (UL94).
Easily removable and made from regen-
erable materials. May be cleaned by
washing.
SUCTION AND DELIVERY GRILLE
UNIT
(GLL range accessories)
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 suction with a filter and air deliv-
ery fins, but also a special electric box
with bayonet coupling to the connector
that is bound to the unit's load-bearing
structure.
The form and opening of the suction lou-
vres were developed in order to have
the best possible distribution of the air,
both when functioning in winter as
well as in summer.
Intake occurs through the central grille,
and delivery through the adjustable,
outer slots. In plastic, colour RAL 9010,
it contains the air filter that can be eas-
ily removed for cleaning.
The same standard FCL unit can be con-
fi gured in a number of versions by sim-
ply combining it with different grille
units of the GLL range (obligatory
accessories) to determine its working
modes:
- GLL 10 M (for Module 600 only)
With remote control, fi ns adjustable from
the remote control, IR receiver inte-
grated in the grille. GLL-M has an elec-
tronic thermostat able to manage all the
confi gurations (heating coil with valve,
cooling coil with valve, supplemen-
tary or replacement electric heater) as
well as all the functions (heating, cool-
ing, continuous or thermostat-operated
ventilation, dehumidifi cation, timed
switch-on or switch-off operations).
When working with the electric heater,
the ventilation is only active at maxi-
mum and medium speeds.
- GLL 10 R (for Module 600 only)
GLL 20 R (for Module 840 only)
With remote control, manually adjusted
fi ns, IR receiver integrated in the grille.
GLL-R has an electronic thermostat able
to manage all the configurations (heat-
ing coil with valve, cooling coil with
valve, supplementary or replacement
electric heater) as well as all the func-
tions (heating, cooling, continuous or
thermostat-operated ventilation, dehu-
midification, timed switch-on or switch-
off operations). When working with the
electric heater, the ventilation is only
active at maximum and medium speeds.
- GLL 10 (for Module 600 only)
GLL 20 (for Module 840 only)
Version with manually adjusted fi ns, must
be interfaced with a single or central-
ised external control panel (not includ-
ed). 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 accessories of
the SIT range allow several FCL units -
complete with GLL to be connected in
a single network and commanded from
a single control panel (for the selection,
consult the characteristics and compat-
ibility of the accessories).
CONTROL PANEL (Accessory)
The units with a GLL10 or GLL20 grille
unit must be used with an external con-
trol panel (see the compatibility and
functions of the control panels).
