External electrical connection
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).

Measuring tubes that leave at the of top the hood are intended to
be connected to the smoke limiter that is sold as an accessory. If
the assembly does not include a smoke limiter, the tubes are left
unconnected. Separate air flow measurement instructions are
delivered with the smoke limiter.
