Note the following when selecting the installation location
Select a suitable installation location for parapet or soffit installation.
- ATTENTION: Damage to the unit. Always install the mounting sleeve load-free and do not apply any loads to the mounting sleeve. When installing the parapet wall never stand on the mounting sleeve to avoid damage. Recommendation: Protect the mounting sleeve with a wooden plank until the window sill is installed. If a window sill is installed, it distributes the load.
- ATTENTION: Damage to the unit. No fixing points are permitted in the area of the mounting sleeve. Then, final installation of the ventilation unit is not possible.
- ATTENTION: Damage to the unit.
Do not place half starting stones on the mounting sleeve. - When installing the soffit, to transfer the load, lay the bricks over the mounting sleeve in a semi-offset position.
- Do not install the mounting sleeve in the area of structural elements with vertical centre posts. There may be statically loaded areas in the centre parapet area of the wall opening.
