f Measure the wall thickness, including thermal insulation and
plaster.
The marked measuring scale helps you to adjust the wall mount
casing to the wall thickness.
Note
The corners of the wall mount casing must finish flush
with the wall.
f Slide the two parts of the wall mount casing into each other
or pull them apart.
f To secure the halves of the wall mount casing in position and
seal the overlap, wind suitable adhesive tape around the
joint. The adhesive tape must be airtight and must stick to
plastic. The adhesive tape must be designed for the tempera-
tures expected at the installation site.

must not be facing down. Otherwise, condensate from the
wall mount casing may penetrate the wall.

marked measuring scale is at the top.
f Push the wall mount casing a little way into the wall.
