Prior to mounting prepare holes for the telescopic duct, the outer box and the ventilating unit. Install the telescopic duct in the hole
and fill the gaps between the duct and the wall with a mounting foam. For easy mounting keep the clearances between the duct and the
wall within 5-10 mm (3/16’’-3/8’’). Fix the outer block according to the wall holes with four 4x35 screws included into delivery set and the
matching dowels 6x35.
Fix the air duct with smaller cross section to the wall with the screws 4x35 from the delivery set and the dowels 6x35. Then fix the
ventilating unit to the latches. The hole spacing for fastening of the air duct with smaller cross section is shown in fig. 5. The hole spacing
for the outer boxes fastening is shown in fig. 6.
