drain valves, located respectively on the
highest and lowest point of the battery
circulation.
THREE-WAY VALVE
Internal 3-way valve, of the all-or-nothing
type, with fast connection actuator and
visual signalling of the position, assem-
bled as standard on the heating/cooling
coil, powered with a voltage of 230V ~
50Hz.
FAN UNIT
The fan unit, with the latest axial-centrif-
ugal fan designed to obtain low-sound
emissions, is dynamically and statically
balanced.
The three-phase brushless electric motor is
powered by a dedicated inverter device
that allows the ventilation speed to be
continuously varied.
The electric motor is cushioned with elastic
supports and the steel shaft is mount-
ed on bearings and resists salty fog in
accordance with ASTM B117/64.
The fan unit can be easily accessed for
cleaning and maintenance.
CONDENSATE DISCHARGE DEVICE
The condensate discharge device disposes
INSTALLATION
WARNING: before carrying out any
work, make sure the power supply is dis-
connected.
WARNING: before carrying out any work,
put the proper individual protection
devices on.
WARNING: the device must be installed in
compliance with the national plant engi-
neering rules.
WARNING: the electrical connections, the
installation of the fan coils and relevant
accessories should be performed by a
technician who has the necessary techni-
cal and professional expertise to install,
modify, extend and maintain systems, and
who is able to check the systems for the
purposes of safety and correct operation
(in this manual they will be indicated with
the general term "persons with specific
technical skills").
In the specific case of electrical wirings, the
following must be checked:
- measurement of the electrical system
insulation strength
- continuity test of the protection wires
WARNING: install a device, main switch, or
electric plug so you can fully disconnect
the device from the power supply.
The essential indications to carry out a
proper installation are given below.
The final touches to all the operations are,
however, left to the experience of the
installation engineer in accordance with
the specific needs.
The water, condensate discharge and elec-
trical circuit ducts must be provided for.
The fan coil should be installed in such a
way as to facilitate routine (filter clean-
of the condensate that is produced by
the unit and deposited in the polysty-
rene basin. The device consists of a con-
trol board, a non-return valve, a 3-level
float, and a pump with a maximum head
of 800mm. The unit can be easily con-
nected to the condensate discharge sys-
tem by means of a plastic connector with
an external Ø of 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 connections for the
water.

as well as access to the air drain valve on
the side of the unit frame (connections
side).
Do not install units in rooms where there
are inflammable gases or acid or alkaline
substances that could irreparably damage
the aluminium-copper heat exchanger or
internal plastic parts.
Do not install the unit in workshops or
kitchens, where oil vapours mixed with
the treated air can be deposited on the
exchange coils, reducing their effective-
ness, or on the internal parts of the unit,
damaging the plastic components.
The fan coil must be installed in such a
position that the air can be distributed
throughout the room and so that there
are no obstacles (curtains or objects) to
the passage of the air from the suction
grilles.
Choose a position at the centre of the
room whenever possible; adjusting the
air output allows air to be distributed
optimally within the room. Generally the
best position of the fins is that which
allows the launch of the air adhering to
the ceiling for the coined effect, during
cold functioning.
On the side of the deflectors there is an
indication of the opening positions for
correct operation:
- Module 600 (GLLI) 20 ° hot opening;
- Module 600 (GLLI) 10 ° cold opening;
- Module 840 (GLLI) 25°; 100% hot opening;
- Form 840 (GLLI) 50 ° cold opening;
The form and opening of the intake slats
were developed in order to have the
best possible distribution of the air, both
when functioning in winter as well as in
summer.
Suction occurs through the central grille,
and delivery through the manually
adjustable, perimetric slots. In plastic,
colour RAL 9010, it contains the air filter
that can be easily removed for cleaning.

FILTERING SECTION
Mechanical air filter with ABS frame, colour
RAL9010.
Filter in filtering class G1, self-extinguishing

Depending on the user's needs, the fins can
be adjusted to the intermediate positions,
or completely closed.
Thanks to the special shapes of the fins,
the machine can also function with the
deflectors completely closed.
Do not install at a height above three
metres.
The FCLI unit is prepared for connections
with channelling for the fresh air and for
the delivery of treated air to an adjacent
room.
