• Start on the bottom shift the lateral sealing plates with the slightly bent surface behind the fasten-
ing proles. Make sure the sealing plates on top of each other covers and overlaps the subjacent
sealing plate. Slightly tighten the self-tapping screws of the appropriate fastening prole after
the sealing plates have been positioned to ensure that the sealing plates do not slip downwards
but can still be moved.
• Evenly allocate the overlapping of the sealing plates over the duct height. Shift the topmost seal-
ing plate ush to the duct ceiling and the lowest sealing plate ush to the duct oor, then tighten
all self-tapping screws on the fastening proles.
