Bring the delivery sections in the exact mounting position and push them together as near as pos-
sible. The screw holes on the flanges have to lie opposite now.

The precisely aligned and parallel flanges are connected with the enclosed screws. Initially, all
screws are only loosely screwed as follows:

-
If accessible, in the connection angles located in the upper corners of the unit (Figure 58 bot-
tom center).
-
If accessible, in the circumferential connection frame (Figure 58 top center).
In the panels (Figure 58 right).
