The installation location must be level and have adequate load bearing
capacity (see data sheets for individual unit weights). Level the unit
horizontally (align using the adjustable feet). The installation site must be
able to bear the load of the ventilation unit without vibrations on a long term
basis. Provide sufficient space at the front of the unit for maintenance work.
Site the unit in a room that is free from the risk of frost!
