• If the hood is used in its recirculation mode, it will operate simply

and safely in the above conditions without the need for any of the

aforementioned measures.

• 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.
