THE VENTILATOR.
ATTENTION!
DO NOT BLOCK THE AIR DUCT OF THE INSTALLED VENTILATOR WITH DUST
ACCUMULATING MATERIALS, SUCH AS CURTAINS, CLOTH SHUTTERS, ETC. AS IT

1. Prepare round core holes in the outer wall.
Prepare one or two round core holes in the outer wall, depending on the ventilation system equipment.
For efficient operation of the ventilation system it is recommended to install the ventilators as far apart from one another as possible.
While preparing a core hole make preparations for layout of the power cable and other required cables.
The core hole size and minimum distance to a mounting surface, for example, a wall, ceiling or a window as well as the minimum
distance between the ventilators are shown below.

Measure the wall thickness B.
The air duct length is calculated as L = B + A, where A means an air duct
segment that protrudes in the outer wall to enable installation of the
external grille of the outer ventilation hood. For details, see the table
