• The exhaust air line should be as short and straight as
possible.
• To avoid excessive noise or a reduced
extractioncapacitythediameteroftheexhaustair
pipeline should not be less than 150 mm.
• Use or form only large radius bends.
Small radius bends reduce the extrac-tion capacity
of the hood.
• Use only smooth pipelines or flexible
hoses of non-flammable materials for the exhaust air
pipeline
• If the exhaust air pipeline is horizon-
tally routed, there must be a minimum gradient of 1
cm per metre or an incli-nation angle of 2°. (

)
Otherwise condensation water could run into the
extractor hood motor.
• If the exhaust air is directed into an
exhaust air duct, the end of the entry fitting must be
directed in the direc-tion of flow.
