Using a unit outside the specified conditions and contrary to the intended use leads to the
loss of all warranty claims. The warranty is limited to units that have been installed exclusively
by trained and certified personnel.
The following should be considered when selecting an appropriate installation site:
• Ensure that installation mode A (standard) or B (optional) can be implemented at the
installation site. If mode B is preferred, please follow the change-over procedure on
page 35. For more information on the air duct connections in mode A/B, please see
page 18.
• The unit is designed for installation in environments at temperature levels >-12 °C. Due to
its compact design, the unit can be set up e.g. in utility rooms with little space or in the
attic.
• Ensure that the wall structure is able to support the weight of the unit regardless of the
type of wall bracket.
• Provide extra space to ensure a proper installation and access for maintenance activities
(see following figure).
The additional space required for maintenance activities is depicted in the following figure
(top view).
