Models provided with a PIR (passive
infra-red) detector (movement detec-
ted with a maximum distance of 4 me-
tres) and with an adjustable “run on”
timer (1 to 30 minutes).

riod set by the over-run timer and
then automatically returns to tric-

a movement is detected and the

selected period set on the over-run
timer (fi g.3).

MAINTENANCE
IMPORTANT: DISCONNECT FROM
THE MAINS SUPPLY BEFORE CARR-
YING OUT ANY MAINTENANCE
The ECO dMEV extract fan is supplied
with a plastic fi lter.
Performance depends on cleaning
frequency and thus we recommend
cleaning, minimum every two mon-
ths, in accordance with fi g 1a.
The ECO dMEV extract fan must
always be operated with the fi lter fi -
tted.Using the extract fan without the
fi lter invalidates the warranty.
The external surfac e of the fan only
requires periodical cleaning using a
cloth lightly impregnated with a soft
detergent.
