Assembly and Start-up
SMART-EC-4000 fans are
meant for work outside the buildings.
It is recommended to install them
on roof bases or wall brackets (delivery on separate order).
To reduce
the noise level, it is advised to apply sound
absorbing roof bases. After the fan is placed
on a roof base, it is important to screw up thoroughly all the mounting bolts between the fan flan-
ge connection
and
the roof base.
In the Fig. No.2
are given the
dimensions of the mounting flange and sound absorbing roof bases.
