MOUNTING
WARNING
Read the operation manual prior to any electric installations. Connection of the unit to power mains is allowed by qualified professionals.
The unit is designed for through-the-wall mounting in the building outer
wall.
Mounting sequence:
1. Prepare a round core hole through the outer wall. The size is shown in the
gure 7. While mounting several connected in series units provide a recess
for the cable layout during the hole preparation to enable series connection
of several units.
2. Install the telescopic air duct in the wall. The protruding telescopic air duct
section on outer wall side must be equal to the distance A, g. 8.
3. Fill the gaps between the wall and the telescopic air duct with a mounting
foam.
