5. Mounting

5.1 Mounting instructions

● Position outside wall air opening as per
the details of your planning office.
● Install ALD at an incline of around 1...2 %
to the outside wall.
● Recommendation: Install ALD in top part
of window (to right or left of window) at a
height of 2 to 2.20 m.
● It must be possible for the designer cover
[1] to be removed in order to change the
filter. The mounting site should be
selected accordingly.
● Thinner walls will mean reduced sound
insulation.
● Together the three sound-absorbing
elements must be of the same length as
the wall sleeve [11] (otherwise sound
insulation is reduced).
● You will find more information and
planning tips in the Practical guidance for
comfort ventilation, chapter 3.8
