INSTALLATION

ELECTRICAL WIRINGS

The unit must be connected directly to an
electrical outlet or to an independent
circuit.
The FCLI cassette -type fan coils
must be powered with a current of
230V ~ 50Hz (FCLI32_64), 230V ~
50/60Hz (FCLI82_122) with an earth
connection; the line voltage must
however remain within the tolerance
of ±10% compared with the nominal
value.
To protect the unit against short
circuits, fit an omnipolar thermal trip
max. 2A 250V (IG) to the power line
with a minimum contact opening
distance of 3 mm.
The electrical power cable must be of the
H07 V-K or N07 V-K type with 450/750V
insulation if inside a tube or raceway.
Use cables with double H5vv-F type
WARNING: check that the power supply
is disconnected before carrying out
any procedures on the unit.
WARNING: before carrying out any
work, put the proper individual pro-
tection devices on.
WARNING: the device must be installed
in compliance with the national plant
engineering rules.
WARNING: the electrical connections,
the installation of the fan coils and
relevant accessories should be per-
formed by a technician who has the
necessary technical and professional
expertise to install, modify, extend
and maintain systems, and who is
able to check the systems for the pur-
poses 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

insulation for visible cable installation.
For all the connections, follow the wiring
diagrams supplied with the device and
shown in this documentation.
The electric box is supplied with
obligatory accessories (GLLI - GLLI_N).
WARNING: install a device, main switch,
or electric plug so you can fully dis-
connect the device from the power
supply.
The essential indications to install the
device correctly are given here.
The completion of all the operations in
accordance with the specific require-
ments is however left to the experience
of the installation engineer.
See also the installation manual of the
FCLI unit and the user's manual provided
with the grille unit.
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.
The opening positions are indicated
on the side section of the deflectors
(GLLI10N) for correct machine heating
(20° opening) and cooling (10° opening)
operation.
For units with GLLI20N grilles the deflector
should be fully opened in the heating
operation and it should be rotated half-
way in the cooling operation.
Depending on the user's needs, the
fins can be adjusted to the interme-
diate 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.
