External electrical connection
Standard ventilation
The volume flow rate of the air inside the cooker hood is
measured with the damper closed.
Measuring
• The air flow measuring tubes are located behind the cooker
hood light on the right side.
• Connect the differential pressure gauge to the measuring
tube that is marked with a “min.” sticker. The enclosed
figure illustrates the measuring principle.
Adjustment
• Cover the required number of holes in the damper with the
magnetic strip that is delivered with the cooker hood.
• Determine the volume flow rate from the performance
scheme based on the measured pressure and the number
of open holes in the damper.
Boost ventilation
The volume flow rate is measured and adjusted with the damper
open.
Measuring
• The measuring tubes should be connected as specified in
the standard ventilation section.
• The differential pressure gauge is connected to both
measuring tubes. The enclosed figure illustrates the
measuring principle.
• Determine the volume air flow from the performance
scheme based on the measured pressure.
Adjustment
• Cover the required number of holes in the damper with the
magnetic strip that is delivered with the cooker hood.
