1. Install the mounting frame by fitting & fastening the hole in the wall using Ø6 screws.
In the top holes of the mounting frame, we designed special widening, which facilitates the screw fastening.
2. Put the layer of insulation
under the mounting frame.
3. Cut the hole in the insulation so it fits the hole in
the wall.
4. Manually or with pliers, bend the correct fasteners. Both the right and left fastenings
are designed in the manner that includes the slop for possible condensation.
