Mounting a reducer
The reducer can be used to create a reduction from the main duct to a
narrower duct. The following reductions are possible:
•
250 mm-wide duct routing (BSKM 1025) to a duct section of width
110 mm (BSKM 0711)
•
110 mm-wide duct routing (BSKM 0711) to a duct section of width
70 mm (BSKM 0407)
See Fig. 59:
1
Stick the self-adhesive sealing strip to the lock plate.
2
Fasten the threaded rods to the ceiling and fasten the lock plate to
the threaded rods with washers and nuts at the desired height.
3
Shorten the ducts as necessary and then re-drill the duct fastening
holes (see Fig. 12 on page 18). If necessary, use locking brackets
for the duct lid (see "4.4 Inserting locking brackets" on page 19).
Remove the duct lid and fix the duct sections with two self-tapping
screws each (contained in the scope of delivery of the lock plate) on
the lock plate.
Insert cables.
