The ECO DMEV is suitable for wall or
ceiling mounting and can either extract
directly to the outside or through a ducted
system (see Fig. 2).
Make a Ø105 mm hole in the wall or
ceiling.
If the unit is to be installed with ducting,
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 airflow and that the impeller turns
freely.
Introduce the mains cable through the
cable entry (5) and fix it to the wall.
Connect the electrical wiring as set out
below and then mount the protection
cover and the front grille.
Electrical connection
The ECO dMEV is an extract fan
designed for a single phase supply, with
voltage and frequency as indicated on
the rating plate of the unit. The units are
manufactured with double electrical
insulation (Class II) and therefore they do
not need an earth connection.
The electrical installation must include a
double pole switch with a contact
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
diagram applicable to the selected
model.
Operation
The ECO dMEV is an extract fan
designed to operate continuously at low
speed and constant volume. The
constant flow setting is made with dip-
switches placed on the electronic circuit
board (Fig. 1):
