• When the hood is used in its extraction mode, the following rules
must be followed to obtain optimal operation:
— short and straight outlet hose
— keep bends in outlet hose to a minimum
— never install the hoses with an acute angle, they must always
follow a gentle curve.
— keep the hose as large as possible (preferably the same diameter
as the outlet hole).
— the length should be no more than:
3 metres with one 90° bend
2 metres with two 90° bends
Bends of more than 90° will reduce the efficiency of the hood and
reduce the airflow.
•
Failure to observe these basic instructions will drastically reduce
the performance and increase the noise levels of the extractor
hood.
