.2 Connecting air ducts and components
When connecting the air ducts, ensure that they are airtight and are suitably vibration
dampened.
The air ducts and add-on parts such as sound absorbers etc. may only be attached to the ventilation
unit using adequately dimensioned fastening elements to suitable, solid wall or ceiling structural
elements.
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 may damage components such as fan blades.
Project specifications require that air duct and installation components be suitably and adequately
insulated.
Remove all tools and assembly materials from the unit when work is complete.
Ensure that no tools or assembly materials remain in the unit, since these may
damage or destroy the unit when starting up.
Ensure that the housing seals well and reliably against the closing front door, to
guarantee airtight and condensate- tight sealing.
