Electrical Wirings - AERMEC GLLI10N Manual De Uso

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 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 insulation for visible
cable installation.
WARNING: check that the power sup-
ply 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 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

NSTALLING NEAR A WALL
If the unit is to be installed near a wall,
the corresponding delivery outlet can
be closed using the gasket supplied.

For all the connections, follow the
wiring diagrams supplied with
the device and shown in this
documentation.
The electric box is supplied with
o b l i g a t o r y a c c e s s o r i e s ( G L L I -
GLLI_N).
WARNING: install a device, main
switch, or electric plug so you can
fully disconnect 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 pro-
vided 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° open-
ing) operation.
For units with GLLI20N grilles the deflec-
tor should be fully opened in the heat-
ing operation and it should be rotated
halfway in the cooling operation.
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 connec-
tions with channelling for the fresh air
and for the delivery of treated air to an
adjacent room.
