- SILENT-100 DESIGN: 100 mm
- SILENT-200 DESIGN: 125 mm.
- SILENT-300 DESIGN: 150/160 mm.
Ensure that there are no obstructions to the
airflow and that the impeller turns freely.

Electrical connection
The SILENT DESIGN is an extractor
designed for a single phase supply, with
voltage and frequency as indicated on the
rating plate of the unit. The units are
manufactured
with
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.
