WARNING
In case of a sandwich panel installation, the fans cannot be fixed directly on the "foam" sidewall, but
a proper metal supporting structure shall be used for steadily holding the fans in place as shown in Figure 1.
WARNING
There must be no obstacle neither in front or behind the fans. The outgoing airflow must be kept
free at least of a length of 3-times fan diameter and the ingoing airflow must be kept free at least in a radius of
1.5 m distance in front of the fan.
