28 Installation
3. Mount vertical support(s):
Note: This step must be carried out only on air ducts /AHU's with a width >2000 mm.
• Mark horizontal position(s) of the vertical support(s) on the cross members. From the back (view
in air ow direction) attach the vertical support(s) with the same distance to the duct ceiling
as the lateral supports of the nozzle system have, then x the vertical support(s) four screws
M6 x 16 mm and nuts to the cross members. Slightly fasten the screw connections only.
• Check distance between upper edge of the vertical support(s) and the duct ceiling as well as
the vertical alignment of the vertical support(s) by measuring the distance between the vertical
support(s) and the duct walls on top and on the bottom.
Important: The distance between the upper edge of the vertical support(s) to the duct ceiling
must be identical to the distance between the upper edge of the two lateral supports of the noz-
zle system to the duct ceiling. If necessary, align vertical support(s) horizontally and vertically.
• Fasten all screw connections.
