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).
Failure to observe these basic instructions will drastically reduce the
performance and increase the noise levels of the extractor hood.
