Mount the flange around the wall inlet, the end with the pieces
driven out must turn downwards, enabling any water to run out.
NB: It is important that the cut edge of the wall is above the inner
side of the flange bottom to prevent water from running into the
wall, see Figure 9.
Tip: Mount one flange in each end of the building and stretch a
line between the flanges.

Concrete wall:
Use 6 mm wall dowel, 4x40 chipboard screw and Ø4 face plate
when mounting on concrete wall.
1) Drill a Ø6 mm hole.
2) Insert a rawlplug into the hole.
3) Hammer the rawlplug as far as it will go into the hole.
4) Fasten the flange with the 4x40 chipboard screw and Ø4
face plate.
Sandwich wall:
Use tapping screw 5x16 flange when mounting on sandwich
panels.
1) Drill a hole according to the table below.
2) Fasten the flange with the tapping screw 5x16 flange.
