Device-side preparation for installation
The ventilation appliance should only be removed from
itspackagingneartoitsplaceofnalassembly.
Note:
Do not lift the appliance out of the packaging by
means of its top or front panel! The top and front
panels are only loosely tted!
• Unpack the appliance.
• Remove the front panel. To do this, push the front
panel approx. 1 cm towards the top side of the appli-
ance and pull it forward and away.
• Pull the top panel upwards out of the spring shack-
les, then tilt it towards the rear in order to remove it
from the slider (Fig. 1, Pos. 3).
• Remove the wall-mounting strip. To do this, remove
the screws (Pos. 1) and take off the bracket to the
rear.

Minimum clearances
The Electric ventilation unit shall be mounted ush to
the wall. Following minimum clearances must be ad-
hered to (Fig. 3):
• from the right-hand side panel
to remove the retractable rotary knob............... 10 cm
• from the left-hand side panel
to remove the retractable rotary knobs............. 10 cm
• above the top panel
to hinge open the top panel.............................. 15 cm
• The free ow of convection air into, and out of the
appliance must be ensured both at the top, and at the
bottom (recommendation: 10 cm) of the appliance.
• When mounting in niches or under projecting window
sills, a minimum height of 840 mm and a minimum
width of 865 mm must be available.
On-site preparation for installation
Beforetheapplianceisnallyinstalled,theexternalair
ducts and a suitable earthed socket 230 V~ must be
installed.
The appliance itself is always to be mounted using the
wall-mountingstrip(„A“,Fig.2),whichistobexedto
the wall with suitable material, dependent on the wall
type.
External air ducting
Before the appliance is installed, the appropriate exter-
nal air passages must be made in the outside wall. This
is done – dependent on the wall material – by installing
suitable ducting in the wall (if necessary with a protec-
tive grille on the outside end).
Round ducting “System 100” (external diameter
104mm)oratducting“System100”(externaldimen-
sions 54 x 110 mm) should be used.
Theairductsmustbecutoffushtotheinsideofthe
wall and should be run with a slight downward incline of
2-3° from inside to out!
The positioning of the ducts in the wall is determined
according to Fig. 3. The wall-mounting strip can be
used as a template to mark the positions (Fig. 2)
The left hand duct is always for the fresh air inlet and
the right hand duct is always for the exhaust air outlet.
The knock-outs in the wall-mounting strip are larger
than the external dimensions of the ducts!
Earthed plug and socket 230 V~
The appliance is of the plug-in type. An earthed socket
230 V~ is thus to be installed at a maximum distance of
50 cm below the left hand side panel of the appliance.
In order to prevent the connecting cable being seen
whentheElectricventilationunitisnallyinstalled,we
recommend, at least in new buildings, that he socket
be installed in the hatched area (“D”, Fig. 2) under the
appliance.
Plug the appliance in only after all installation work has
been completed!
