WARNING: The suction and delivery
grille GLLN is an accessory that must
be connected to the electronic cards
applied to fan coils. Consult the manu-
als of the fan coils and cards (if they
have been provided as an accessory),
and apply all safety precautions indi-
cated for the electronic cards.
WARNING: the fan coil is connected to
the power supply and water circuit.
Operations performed by unqualified
personnel can lead to personal injury
to the operator or damage to the unit
and surrounding objects.
WARNING: Components sensitive
to static electricity may be destroyed
by voltages notably lower than those
at the human perception threshold.
These voltages form when you touch a
component or electric contact of a
unit, without first discharging accu-
mulated static electricity from your
body. The damage caused to the unit
by an overvoltage is not immediately
evident - it only appears after a cer-
tain period of operation.

ACCUMULATION
Any person not connected in a conductive
manner with the electronic potential of
his surrounding environment can accu-
mulate electrostatic charges.
DESCRIPTION
GLL10N (600x600)
GLL20N (840x600)
Intake and delivery grille unit with
"VMF System" advanced
thermostat.
The grille is part of the GLL-N range grille
unit (obligatory accessory).
The form and opening of the suction
louvres 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.
GLL_N needs to be interfaced with an
external control panel VMF-E4 (NOT
SUPPLIED) if installed in a single "stand
alone" FCL unit or as a master unit of
a fan coil slave network (max 5). If the
GLL_N is combined with a VMF-E4
control panel ("Master" configuration),
the fan coil can be connected to a VMF-
E5 central supervisor system.
The FCL units are available in two basic

STANDARD PROTECTION AGAINST
ELECTROSTATIC CHARGES
Earthing quality
When working with units sensitive to elec-
trostatic electricity, ensure that people,
workplaces and unit casings are correctly
earthed. This will prevent the formation
of electrostatic charges.
Avoid direct contact
Only touch the element exposed to elec-
trostatic risk when absolutely essential
(e.g. for maintenance).
Touch the element without coming into
contact with either the contact pins or
the wire guides. If you follow this rule,
the energy of the electrostatic charges
cannot reach or damage the sensitive
parts.
Before taking measurements on the unit,
it is necessary to discharge all electro-
static charges from your body: to do this,
just touch an earthed metal object. Only
use earthed measuring instruments.
MALFUNCTIONING
In the case of malfunctioning remove
the power to the unit then re-power
it and start the apparatus up again.
If the problem occurs again, call your
areas After-Sales Service promptly.
DO NOT PULL THE WIRES

SUCTION AND DELIVERY GRILLE UNIT
(GLLN range accessories)
The FCL cassette-type fan coil is only
complete when used with a grille of the
GLLN range - an obligatory accessory
for the operation of the fan coil with the
VMF system. The grille accessories of
the GLLN range not only offer suction
with a filter and air delivery fins, but also
include a special electric box.
The form and opening of the delivery fins
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 easily
It is highly dangerous to pull, crush or
tread on the electric cables, or to fix
them with nails or drawing pins.
A damaged power cable can cause short
circuits and injure people.
WARNING: Avoid any use of the device by
children or incompetent persons with-
out appropriate supervision; also note
that the unit should not be used by chil-
dren as a toy.
removed for cleaning.
FILTERING SECTION
The air filter is inserted in the suction
grille.
Mechanical air filter with ABS frame.
Filter in self-extinguishing class V0 (UL94).
Easily removable and made from regener-
able materials. May be cleaned by wash-
ing.
