It is important to check that the components are correctly installed for the specific construction conditions (e.g. weight of window casement, surface properties, hole pattern in the brick). Note the guidelines for planning and executing the installation of windows and house doors (art. no. 5995 000 000).
To ensure the fall-proof mounting of windows in line with applicable guidelines and regulations, approved securing systems (e.g. window installation bracket W-ABZ) must be used, or approval is required for each individual case.
Align window frames using alignment clamps or Amo Bag
Screw length = frame width + distance + screw-in depth (see also 55.2 Amo III 11.5 mm)

Guidelines for planning and executing the installation of windows and exterior doors, 2020 edition
Art. no. 5995000000:
The fixture must safely transfer all standard forces affecting the window to the structure and the foundation. The total load must therefore be calculated from e.g. the window load, wind load and working load (see DIN 1055). The currently applicable building regulations stipulate that buildings and their components must be planned in such a way that they do not endanger human life and health or pose a risk to public safety. Attachment of the windows must also comply with this criterion.
When securing window walls compliant with the former DIN 18056 standard or elements with a surface area in excess of 9 m2 and fall-proof glazing as specified in the German technical rules for safety glazing (TRAV) or DIN 18008-4, the following must be observed
The DIN 18056 standard applied to window walls with a minimum surface area of 9 m² and a minimum side length of 2 m on the shortest side. Anchors with general or European technical approval or with individual approval should be used for this application. Similarly, only anchors with a general construction permit or European Technical Approval or with individual approval must be used to attach fall-proof glazing as specified in the German technical rules for safety glazing (TRAV) or DIN 18008-4.
