External electrical connection to the ventilation unit
As the default factory setting, the
following voltages have been set for the
cooker hood:
• Away profile 70V
• At home profile 135V
• Boost profile 230V
To change these values, move the
transformer wires to more suitable
connectors (see the wiring diagrams).

Measuring and adjusting performance values
Standard ventilation
The volume flow rate of the air inside the cooker hood is measured
with the damper closed and, where required, adjusted based on the
static pressure loss and the performance scheme of the cooker hood.
• The static pressure loss is measured from the hole in the damper
using the measuring tube found in the accessory bag (see figure).
• Determine the volume flow rate from
the performance scheme based
on the measured pressure and the
number of open holes in the damper.
Adjustment:
• Cover the required number of holes
in the damper with the magnetic
strip that is delivered with the cooker
hood.
dp
Boost ventilation
The volume flow rate of the air inside
the cooker hood is measured with
the damper open based on the static
pressure loss and the performance
scheme of the cooker hood.
• Measure the static pressure
loss of the cooker hood. The
measuring point must be located 2
times the duct diameter above the
outlet collar of the cooker hood
(see figure).
• Determine the volume air flow based on the measured pressure
and the performance scheme (with the damper open).
