5. Mount the cross members:
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 width >2000 mm the cross members are supplied in sections and
must be bolted together on site. Proceed as follows: Undo the screw connections on the cross
members overlapping. Arrange cross member sections and x them together using the screws
M6 x 16 mm and nuts removed right before. Exactly align cross member sections and fasten the
screw connections. Then, x the reinforcement plates at the overlapping to the cross members
as shown below using four screws M6 x 16 and nuts, align plates and fasten the screw connec-
tions.
• Slightly loosen the four screw connections, with which the mounting plates are attached on both
sides to the cross members, so the mounting plates can be moved.
• From behind (view in air ow direction) hang up the cross members at the appropriate vertical
position to the lateral supports of the post-evaporation unit, then push the cross members down-
wards until they come to a stop. Now, fasten all screw connections of the mounting plates.
