Always ensure that the ventilation unit is mounted in such a way that the ducts are connected to the correct inlet and outlet openings! To prevent noise complaints, Itho Daalderop recommends connecting the two ducts coming from the house with silencers. The ventilation unit is mounted on the wall. - Page 16 Mounting positions High rise 'standard High-rise 'twisted' (1) Low-rise 'standard Low-rise 'twisted' (1) 1) See Conversion for assembly.
