Installation procedure
Mount the metal posts and the wall in accordance with the
specifications of the wall manufacturer and the required ex-
change parts as shown on Figure 14.
Provide a recess for the wet installation of BKA-Ü (pos. 1)
From B > 800 mm (with horizontal damper blade axle), on
both B sides of the exchange profiles, 2 bent perforated
plates each (t ≥ 0.5 mm; width x length = 40 x 70 mm), must
be fastened as mortar anchor (pos. 14). They must be
screwed to the metal profiles at the wall centre, using one
dry-wall screw for each plate.
Insert the BKA-Ü into the wall recess (operating side - ob-
serve the installation dimension of 210 mm). Average out
the circumferential annular gap evenly between the wall
and BKA-Ü. Mounting of BKA-Ü with the help of mounting
suspensions etc.
Insert mortar (pos. 13) into the circumferential gap of 40
mm between the BKA-Ü housing and the circumferential
metal profiles (pos. 10). If reveals (pos. 20) are used, a mor-
tar bed depth of 100 mm is sufficient. When using reveals,
the exchange parts must be adjusted to the recess dimen-
sions.
