6.3. Unit with Different Widths
For units with different widths, there are four different
situations. For an indoor installation the method desc-
ribed below applies to all situations.
Indoor Installation
The top section includes a projecting cross beam that
is effectively as wide as the bottom section.
• Check that the cover strip at the ends of the bottom
section is installed in the correct place.
• Position the top section as indicated in the dimen-
sional drawing.
• Screw the projecting cross beam of the top section
to the corner posts of the bottom section.

• If the top section is shorter than the bottom sec-
tion, the unit ends should be finished as described
below.

• Cut the connection profile supplied to the correct
length and mount it to the unit ends as described
below

mediate base frame
• A longer top section needs no further finish at the
top.

diate base frame
NOTE: For an outdoor installation, seal all joints
resulting from the mounted profiles. This applies
to both corner and butt joints.
