6. Mount the vertical support(s):
Note: This step must be carried out only on air ducts /AHU's with a width >1650 mm.
• For air ducts/AHU's with a height >2000 mm the vertical supports are supplied in sections and
must be bolted together on site. Proceed as follows: Undo the screw connections on the vertical
supports overlapping. Arrange vertical support sections and x them together using the screws
M6 x 16 mm and nuts removed right before. Exactly align vertical support sections and fasten
the screw connections.
• Fix angle bracket(s) (for xing the vertical support to the duct ceiling) to the vertical support(s)
using two screws M6 x 16 mm and nuts. If necessary, remove the corresponding screw connec-
tion on the vertical support(s) rst.
Important: Fix angle bracket in such a manner that the distance between the leg of the angle
bracket and the upper edge of the vertical support has the same distance as the upper edge of
the two lateral supports have to the duct ceiling (see step 1).
