Cutting open the pipe connections
The openings for the connections are still closed when they
are delivered to the building site and must be opened using a
fine-toothed saw (e.g. jigsaw) as required. The cuts may only
be made along the markings provided; construction
elements that are wrongly sawn out must be replaced. The
component structure must not be damaged outside the cut
contours provided.
