ing, use a standard Ø100 mm duct.
Remove the front grille (1) and the
protection cover (2).
The unit can be mounted on the wall
or ceiling using the 4 raw 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 is an extract fan 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 in-
clude a double pole switch with a con-
tact clearance of at least 3 mm.
The electrical cable must enter the
ECO dMEV through the cable entry (5).
Once the cable has been introduced
proceed using the electrical wiring dia-
gram applicable to the selected model.
OPERATION
The ECO dMEV is an extract fan de-
signed to operate continuously at
low speed and constant volume. The
constant fl ow setting is made with
dip-switches placed on the electronic
circuit board (Fig. 1b):

The ECO dMEV may also operate at
high speed that is activated by: an ex-
ternal switch live or light switch
(S, T
and HT versions) an integral humidity
sensor (HT and HTP versions) or an
internal pull cord switch (HTP ver-
sion) .
ECO DMEV S
The ECO dMEV S can operate in two
modes:
Continuous operation on trickle set-
ting only (Fig. 3). Once the air vol-
ume is set the fan is connected to the
mains and the unit will operate con-
tinuously at this air volume.
Continuous operation on trickle with
the ability to boost on high speed.
The ECO dMEV is connected to an ex-
ternal switch or light switch.
When the switch is pressed, the fan
operates on full speed (not constant)
until the switch is turned off (light off):
