Installation and Operating Instructions
Length of wall installation sleeve
ò
Max.: 500 mm
Min.: 300 mm
The length of the wall installation sleeve
comprises the thickness of the uncovered
wall with internal ready-mix plaster, the height
of the feet (
) of the soffit channel and the
ä
immersion depth (
) in the soffit channel
ù
(see Fig. 4 & 5).
m NOTE: The length of the wall installation
sleeve should be adjusted so that there are
no collisions in the area of the shutter rail.
Immersion depth of the wall installation
ù
sleeve in the soffit element
Length: 20 mm
m NOTE: The wall installation sleeve must
not be cut off flush with the wall on the outside!
Soffit channel feet
ä
Max.: 40 mm
Min.: 0 mm
The soffit channel feet determine how far it
sits from the uncovered wall. The height of
the feet and the height of the soffit channel
of 100 mm corresponds to the min. insulation
thickness. If necessary, the feet can be
underpinned .
Distance from core drilling hole (centre)
ë
to the end of the soffit channel
Max.: 480 mm
Min.: 200 mm
The adjustable length of the channel must
be selected depending on the distance
between the core drilling hole (centre) to the
ready-mix plaster in the window soffit. This
distance minus the height of the shortened
plaster frame (
) provides the length of the
ö
shortenable area
.
ë
Height of the plaster frame
ö
Max.: 35 mm
Min.: 15 mm
The height of the plaster frame bridges the
distance between the soffit channel and
the wall grille. The height must be selected
depending on the thickness of the window
soffit insulation and the ready-mix plaster.
The plaster frame allows for tolerance
compensation.
A minimum height of 20 mm is recommended
for the plaster frame.
