8.3 Duct

1. Debur edges on the inside of the duct.
NOTICE
Risk of damage to flexible ducts (folded
spiral-seams ducts) caused by spring
hooks. Snap off the spring hooks prior to
installation of the flexible ducts.
2. If necessary snap off the two spring hooks [1].
3. Perform installation preparations as
described in Chapter 8.1.

8.4 Fan

1. Unpack fan unit. Remove internal grille/
shutter frame [12]. For loosening unlock
both safety catches ( Fig. D) with a
screwdriver.
NOTICE
Damage to unit/functional problems
in the event of rubbing impeller [9].
 Do not fit housing so it is twisted or
crushed. Make sure there is a level seating.

9. Installation

9.1 Installing housing

1. Insert housing [4] in wall breakthrough/wall
sleeve/duct.
2. Align housing [4] horizontally, mark the
two dowel holes, drill the dowel holes
Ø 6 mm and insert the dowels.
NOTICE
Danger of short circuits and damage to
unit. If the power cable is incorrectly fed
or if the cable grommet is not fitted
correctly, water may penetrate into the
fan housing and the degree of protection
cannot be guaranteed. Pierce the cable
grommet [2] or [3] such that the cable
grommet tightly clasps the power cable (cut
in a round shape, no slot). Guide the
surface- or recessed-mounted cables
correctly into the intended cable grommet.

3. Carefully press out the cable grommet [2]
or [3] from the housing [4], then remove
and pierce a round hole in the cable
grommet by means of a grommet puncher.
Use cable grommet [3] for surface
installation and cable grommet [2] for
recess installation.
4. Reinsert the removed cable grommet in
a professional manner, provide sealing
on site if necessary.
5. Guide the power cable into the connection
area such that the cable grommet fits
around the cable sheathing completely.

9.2 Electrical connection

NOTICE
Unit damage in the case of short-circuits.
 Insulate PE conductor and unneeded
cable cores.
 Do not touch electric components.
NOTICE
The opening function of the shutter
frame (K fans) will be hindered by
protruding cables. Cut off and insulate PE
conductor and individual cable cores that
are not required.
NOTICE
Risk of damage to the unit if ESD
sensitive components on the board are
touched [5.2] / [5.3]. Avoid direct touching
of the components or contact surfaces.
1. Switch off mains fuse, secure against
being accidentally switched back on and
position a warning sign.
2. Only lay single cable cores in the unit.
Remove the power cable cladding and
insulate the ends of the cable cores.
