The unit's connectors must be connected
to air duct connections. Airtightness and
vibration isolation must be ensured.
Air pipes and attachments such as sound
absorbers etc. may only be attached to
the ventilation unit using adequately
dimensioned elements for mounting to
suitable solid wall or ceiling structural
components.
Avoid using flexible hoses for connections
to the unit. When making connections,
ensure in particular that no tools or
assembly material will fall into the
connections to the unit or onto the
unit itself. This could cause damage
components such as fan blades. Air
duct and installation components must
be suitably and adequately insulated in
accordance with project specifications.
