1. General notes
The cooker hood needs a sufficient and correct supply of air to achieve an optimum effect and maximum
ventilation efficiency. If not enough fresh air is supplied, the speed of the fan motor increases, the air
throughput decreases and the noise level rises.
When the filter mats are saturated the air throughput of the cooker hood decreases and the vapours are
only cleaned to an inadequate extent.
The minimum distance between the edge of the hood (IKD 1157.1 / KD 957.1) and the cooker must be
at least 650 mm for gas cookers and at least 500 mm for electric cookers.
The cooker hood is designed for the extraction of the emerging vapours. The cooker hood is delivered
in exhaust air operation. If the extraction to the exterior is not possible, activated carbon filters have to
be inserted for the circulating air operation.
2. Electronic controls
By pressing lightly the control keys on the front the desired extraction power can be set.
The control lights above the keys indicate the set extraction power of the cooker hood.
The lighting is switched on or off by slightly pressing .
3. Programming the air extraction time
The factory setting for the extraction time is 10 minutes. This time is activated when the control key for
the desired power setting is pressed for 2 seconds. The according control light flashes and stops flashing
again after 10 minutes. The cooker hood switches off automatically.
To set another extraction time, proceed as follows:
1. Press lightly the control key.
2. Select the desired extraction time on the scale with 5, 10, 20 and 30 minutes and confirm the with
the according control key. The control light flashes and indicates the programmed extraction time.
Confirm by once againg pressing the control key.
3. Select the desired extraction power, it will be switched on for the programmed extraction time.

4. Lighting
The lighting can be used at any time even when the fan is switched off.
5. Metal grease filters
Both grease filters are dismantled by pressing the respective lock downwards.
6. Charcoal filter
For the recirculating air mode you need two activated charcoal
filters.
• When the filter effect is run-down (depending on use up
to 12 months) they have to be replaced.

Dismantling and installation of the activated charcoal filters
After dismantling the grease filters attach the active charcoal filters to the aspiration hole of the motor.
To do so, adjust the Bayonett fitting on the motor casing and turn the filters in order to fasten them as
shown in the illustration.
7. Installing the recirculating air diverter
In the case of the recirculating air mode, a recirculating air
diverter must be installed so that the cooking fumes extracted
can escape through the ventilation openings on the side of the
upper chimney.
Subsequent to installing the upper chimney mounting support
(A), attach the recirculating air diverter (B) with screws as
shown in the illustration.
Then connect the recirculating air diverter to a pipe (diameter
of 150 mm) and to the motor outlet. Hose clips should be used
for connecting.

9. Accessing components
9.1 Replacing the halogen lighting and the lamp body
Remove part (A) by turning it as shown in the illustration.
Remove the lamp (B) from its mounting support. On installing a new halogen lamp, do not touch the
glass bulb with your bare hands. The maximum lamp power is 20W.
We recommend that you use a dry cloth in order to protect the lamp.
Replace part (A) by turning it, so that it clicks into place as shown in the illustration.
In order to demount the entire body of the lamp the grease filters must firstly be removed. Then remove
component (A) and press the two plastic flaps of the lower part of the lamp together above the bar (C)
and, pressing lightly downwards, release the lower part of the lamp and remove it.

9.2 Demounting the switch unit
If you loosen the two front metal screws in the bar (C) you will be able to remove the switch unit on the
side above the bar.
9.3 Accessing the mains supply, transformer and electronics unit
Once the lower chimney has been removed all three components are accessible.

9.4 Demounting the motor and the fan wheel from the KD 957.1
In order to demount the motor (KD 957.1) the hood should be taken off the wall. To do so, remove the
upper chimney and the lower chimney, take out the grease filters and remove both of the safety screws
on the back wall of the hood body inside the suction shaft. Remove the extraction hose on the motor
support and pull out the non-return valve. Then loosen the screws on the mounting brackets, gently
press the hood upwards, remove it from the wall mounting support and pull it out towards the front. Place
the hood on its back on a scrape-resistant surface. Remove the switch unit as indicated in 9.2, remove
the halogen lamps completely as described in 9.1. Loosen the screws (1) and then pull out the mounting
plate with the motor and the cables (switch and halogen lamps) upwards. Now loosen the screws (2) and
remove the motor with its casing from the mounting plate. Remove the screws from the motor casing.
The screw on the fan wheel can then be removed and the motor or the fan wheel can be replaced.
The installation procedure is carried out in reverse.

9.5 Demounting the motor and the fan wheel of the IKD 1157.1
In order to demount the motor, the lower chimney must be pushed upwards, subsequently ensuring that
it does not slip down (risk of injury). Loosen the 8 screws of the front plate and then remove the grease
filters. Now loosen the two screws at the front and remove the front plate. After removing the front plate,
loosen the 4 screws (2 on the left and 2 on the right) of the support.
Then remove the support plate for the motor with the mains supply box, the electronics unit and the
halogen transformer by means of tilting it to the side. Loosen the 4 screws and remove the motor from
the support plate. Finally remove the 6 screws of the motor casing in order to be able to replace the motor
or the fan wheel.
The installation procedure is carried out in reverse.
