This appliance is conside-

red to be suitable for use
in countries having a warm
damp equable climate as
specified in IEC 60721-2-1.
It may also be used in other
countries.
The SILENT DESIGN is an extractor
designed for a single phase supply,
with voltage and frequency as indi-
cated on the rating plate of the unit.
The units are manufactured with dou-
ble electrical insulation (Class II) and
therefore they do not need an earth
connection.
In addition to the switch shown in the
installation drawing/diagram, there
must be an All Pole switch in the fixed
wiring with a contact opening of min
3 mm.
The electrical cable must enter the
SILENT DESIGN through the cable
entry (4).
Once the cable has been introduced
proceed using the electrical wiring
diagram applicable to the selected
model.
