Installation
Calculating the worktop cut-out
The frames of the ProLine elements overlap the worktop at the outside right and
left by 8 mm on each side.
 Add up the widths of the ProLine elements and subtract 16 mm from this figure.
Example:
288 mm + 288 mm + 380 mm = 956 mm - 16 mm = 940 mm
The ProLine elements are 288 mm, 380 mm or 576 mm wide depending on the
ProLine elements (see "Building-in dimensions" in the "Installation" chapter).
Spacer bars
When installing several ProLine elements, an additional spacer bar must be fitted
in between the individual ProLine elements. The position for securing the spacer
bar will depend on the width of the ProLine element.
