INSTALLATIoN
Installation
10.3.5 Overflow apertures
Living rooms and bedrooms are only supplied with air. Air is only
extracted from rooms where odours and moisture are generated.
Ensure an unimpeded overflow and consequently air balancing.
Install ventilation grilles in internal doors or walls, or enlarge the
air gap beneath the door to ≥ 8 mm.
10.3.6 Cleaning apertures
f Fit cleaning apertures when installing the air ducts, so
that the air ducts can be inspected and cleaned at regular
intervals.
10.3.7 Supply and extract air vents
Supply and extract air vents for the living space are available for
wall or ceiling mounting.
When venting the kitchen, ensure that the extract air vent is fitted
as far as possible from the cooker.

10.4 Fitting the front panel

f Push the plug on the cable leading to the programming unit
into the appliance.
f Hook the front panel into the hooks provided at the front of
the appliance.
f At the upper edge of the front panel, screw in the two screws

10.5 Programming unit

10.5.1 Installation location of the programming unit
The programming unit is connected with an I²C bus. The length
of the bus cable between the programming unit and ventilation
unit must not exceed 20 m.
Observe the following installation location requirements to ensure
correct function.
f Fit the programming unit to an internal wall, but not in a
recess.
f Do not cover the programming unit with curtains or similar.
f Do not expose the programming unit to any direct external
heat source (e.g. the sun, a heater or a TV set).
f Avoid direct draughts coming from windows and doors.
10.5.2 Installing the programming unit
f Route a 4-core bus cable from the ventilation unit to the
mounting position of the programming unit. Use a screened
electronic cable such as LiYCY 2x2x0.8 mm². Do not route the
cable parallel to a three-phase cable.
The BUS cable must protrude 20 to 30 cm out of the wall to allow
installation.

Remove programming unit from the wall mounted enclosure
f Release the locking tab found in the opening on the under-
side of the wall mounted enclosure. Press the locking tab
with a screwdriver.
Installation with a flush box
For securing to a wall we recommend using a flush box, which can
hold the part of the bus cable protruding from the wall.
f Make sure that the screws supporting the flush box are ar-
ranged either vertically or horizontally opposite one another.
f Route the bus cable through the aperture in the wall mount-
ed enclosure from the back.
Installation without a flush box
f To secure the wall mounted enclosure, drill four holes
(Ø 5 mm).
f When routing the BUS cable, be careful not to damage the
cable when drilling the fixing holes.
In the area around the cable entry (behind the wall mounted en-
closure), a reservoir needs to be made to hold 20 to 30 cm of data
cable.
f Break out one of the knock-outs in the wall mounted
enclosure.
f Route the bus cable through the aperture from the back.
