4.2.3 Mounting the nozzle system
1. Mount the lateral supports of the nozzle system to the duct walls:
• Align the lateral supports with the “TOP” labeled mounting bracket on top with an identical dis-
tance to the duct ceiling (target measure ”a”: 65 mm, admissible range: 0...90 mm) and with
a distance “d” of 780 mm +120/-180 mm to the supports of the post-evaporation unit, then x
them via the topmost fastening hole to the duct wall using self-tapping screws 6.3 x 25 mm (do
not tighten the screw yet).
• Align both supports at right angles to the duct ceiling and check the distance to the duct
ceiling once more (the distance must be identical for both supports). Then, x both supports
approx. every 30 cm with self-tapping screws 6.3 x 25 mm to the duct walls.
Note: evenly allocate the self-tapping screws over the entire length of the supports.
