Remove the front grille (1) and the
protection cover (2).
The unit can be mounted on the wall
or ceiling using the 4 plastic plugs
and the screws provided.
Ensure that there are no obstructions
to the airfl ow and that the impeller
turns freely.
Introduce the mains cable through the
cable entry (5) and fi x it to the wall.
Connect the electrical wiring as set
out below and then mount the protec-
tion cover and the front grille.
ELECTRICAL CONNECTION
The ECO dMEV LC is an extractor de-
signed for a single phase supply, with
voltage and frequency as indicated on
the rating plate of the unit. The units
are manufactured with double electri-
cal insulation (Class II) and therefore
they do not need an earth connection.
The electrical installation must inclu-
de a double pole switch with a contact
clearance of at least 3 mm.
The electrical cable must enter the
ECO dMEV LC through the cable en-
try (5).
Once the cable has been introduced
proceed using the electrical wiring
diagram applicable to the selected
model.
OPERATION
The ECO dMEV LC is an extractor fan
designed to operate continuously at
low speed (adjustable) with the facility
to be set to high speed (fi xed) through
the following functions depending on
the version: an external switch live or
light switch (
S, T and HT versions);
the humidity sensor ( HT and HTP ver-
sions); the internal pull cord switch
( HTP version ) ; or the PIR detector ( DT
version ).
The extractor can also be used for in-
termittent operation with adjustable
speed at installation.
In both cases the speed setting is
done when installing the extractor,
with the potentiometer (7) placed on
the electronic PCB (fi g.1b).
Please commission the fan at 9l/s or
above to meet SAP requirements.
The selection between continuous
operation and intermittent operation
is done with the dip-switch 9:
Continuous operation: ON
Intermittent operation: OFF
ATTENTION : In intermittent opera-
tion, mount the backdraft shutter on
the fan outlet.

Once the air volume is set the fan
is connected to the mains and the
unit will operate continuously at
this air volume.
2. Continuous operation on trickle
with ability to boost at high speed.
