9. Mounting instructions

NOTICE
Damage to unit/functional problems
in the event of rubbing impeller [8].
Do not fit connecting flange [3] so it is
twisted or crushed. Make sure there is a
level seating.
Danger of short-circuits/damage to unit
as a result of build-up of condensation
in fan housing.
 Thermally insulate ventilation ducts in a
professional manner.
● Minimum wall thickness:
EN/ENR 20 and EN/ENR 25: 105 mm
EN/ENR 31: 130 mm
● Make sure there is sufficient space to the
wall or ceiling.
● Select installation site where foreign
bodies will not be accidentally drawn in.
● Any installation position can be selected.
● Electrical connection can be either
surface- or recessed-mounted.
● Use mounting material suitable for base
and of sufficient dimensions.
● In order to guarantee the degree of
protecttion (IP value), the cable grommets
[T...] must be drilled through/pierced cor-
rectly, i.e. with a circular hole that is some-
what smaller than the cable diameter.
● Never dismantle the shutter  Damage
to the unit. Only mount the shutter on a
level surface in order to guarantee the
shutter function.
● If electric "shutters with plug connections"
are present, disconnect the connector and
wire the individual cable cores in
accordance with the wiring diagram in
Chapter 17.
10. Mounting
10.1 Wall mounting (Figures 2A to 2H)
1. Switch off mains fuse, secure against
being accidentally switched back on and
position a warning sign.
2. Mark and drill dowel holes, for connec-
ting flange drilling distances  Fig. 2A.
3. Fit wall breakthrough, power cable [L]
(surface-mounted AP or recess-mounted
UP) and if necessary wall sleeve WH.
Lay an empty ducting [9.4] with a slight
incline towards the outside, for an
electrically operated shutter  Fig 2B.
4. Take off internal cover [1]  Fig. 2C.
The internal cover can be taken off the
connecting flange [3] without any tools.
To do this, grip connecting flange, swivel
out internal cover [1] at the underside
and remove upwards
5.
For surface-mounted connection, remove
protective bar [1.1].
6. Remove the terminal box cover [2].
7. Pierce desired cable grommet [T...]
( Fig. 2D) of connecting flange all the
way round and insert power cable [L].
8. Attach the connecting flange [3] to the
wall with suitable mounting material
 Fig. 2E.
9. Fit shutter in accordance with relevant
instructions  Fig. 2F. For electrically
operated shutter, guide connection cable
through duct [9.4] into connecting flange
and guide through black grommet [T5]
into terminal box. To prevent moisture
from entering the terminal box, pierce
grommet all the way round and slightly
smaller than the connection cable. The
cable grommet must tightly seal the
connection cable.
