Mounting on the ceiling

On rafter frames or other frame structure with M8 thread bars so that they withstand the weight of the unit.
Horizontally, because the levelness of the ceiling mounting plate determines the levelness of the unit.

Note:

Install the ventilation unit in a place where the temperature does not drop below +10°C.

Insulate the outdoor air and exhaust air ducts against condensation also between the unit and the ceiling mounting plate.
