1. Safety

Danger!

Repairs may only be carried out by a qualified electrician!

Improper repairs can be extremely dangerous for the user.

It is essential that you observe the following instructions in order to prevent electric shocks:

• The casing and the frame may be live in the event of faults!

• Touching live components inside the appliance may cause dangerous currents to flow through your

body!

• Disconnect the appliance from the mains prior to carrying out any repair work!

• When inspecting live parts, a residual current circuit breaker must always be used!

• The earthed conductor resistance must not exceed the resistance specified in the standard! It is vital

for ensuring the safety of persons and the functioning of the appliance.

• On completion of repairs, an inspection must be carried out in accordance with VDE 0701

[Association of German Electrical Engineers] or in accordance with the corresponding regulations for

your country!

Make sure you observe the following instructions:

• The appliances must be disconnected from the mains prior to all repairs. If inspections must be

carried out on live appliances, make sure you use a residual current operated device.

Attention!

Sharp edges: Use protective gloves.

Components may be electrostatic!

Observe handling precautions!

2. General Information

Changing the specification or attempts to modify the product are dangerous. For your own safety spare

parts should be installed by an authorised, qualified specialist. The manufacturer accepts no liability for

damage which occurs as a result of improper installation or failure to observe currently-valid regulations

for this type of application. Please read through the installation instructions carefully prior to commencing

with work.

The cooker hood requires a sufficient flow of inlet air in order to function optimally and ensure maximum

ventilation. If the supply of inlet air is insufficient the speed of the ventilation fan will rise, the flow rate will

drop and more noise will occur.

The air flow of the cooker hood will drop when the filter mats have become saturated and vapours will

not be sufficiently removed.

The cooker hood has been designed to extract vapours generated during the cooking procedure. The

hood is supplied for extraction air operation. If it is not possible to extract the air to the outside, special

accessories are available to convert the hood to recirculating air operation with charcoal filters.

With the help of cooker hoods steam and odours

that arise during the cooking procedure are

extracted out of the kitchen through a special

discharge device. Fresh air is drawn into the

kitchen through an air opening to the outside to

replace the extracted air.

This effect is generated in the suction module in the

hood which extracts the air under the hood and

leads it to the outside through the air hole. The

hood is also fitted with a control panel for the

extraction modes and a functional lighting system

for the hob. If the hood is installed professionally,

regularly maintained and the safety regulations are

closely observed, it will provide long years of

reliable service.

3. Installation

3.1 General installation instructions

Dimensioned drawing

On installing the cooker hood, the following points are to be observed in addition to currently-valid safety

instructions and the respective instructions of your country:

1. The cooker hood must always be installed above the centre of the hob.

2. The clearance may not be smaller than that stipulated for instalment.

The minimum clearance between a hob and the lower edge of the hood is 250 mm.

3. Exhaust air may not be discharged into a smoke or exhaust gas chimney which is in operation;

nor may it be discharged into a shaft used for ventilating rooms where hearths or fireplaces have

been installed. Should exhaust air be discharged into smoke chimneys or exhaust gas chimneys

which are not in operation, prior approval must be granted by the master chimney sweep

responsible.

4. In the case of extraction air operation of the cooker hood and the simultaneous operation of

heating systems requiring a chimney (such as gas, oil or coal heaters, flow heaters or hot water

boilers), a sufficient supply of inlet air, required by the heating system for combustion purposes,

must be ensured. Negative pressure in the location of a fireplace may not exceed 4Pa

(0.04mbar). This is achieved if it is possible for more air to flow in. The entire ventilation system of

a house or apartment must always be taken into consideration when assessing this.

In the case of the recirculating air mode of the cooker hood, operation can be carried out

without any restrictions.

5. The cooker hood may only be installed above a fireplace for solid fuels where there may be a risk

of fire (e.g. flying sparks) if the fireplace has a fully-enclosed permanent cover.

3.2 Installation

3.2.1 Mounting holes and clamps

1. Draw a vertical line up to the ceiling or to the top demarcation in the middle of the area onto which

the hood is to be mounted.

2. Draw a horizontal line at least 960mm above the hob.

3. Mark a dot (1) on the horizontal line 200mm to the right of the vertical gauge line.

4. Repeat this procedure on the opposite side and check the alignment.

5. Mark another reference dot (2) as described 180mm from the vertical reference line and 362mm

from the hob.

6. Repeat this procedure on the opposite side and check the alignment.

7. Drill the dots (1) marked with a Ø 12mm drill.

8. Drill the dots (2) marked with a Ø 8 mm drill.

9. Insert the dowels and the clamps (11a) and screw them tight.

10. Insert the dowels (11) into the hole (2) and screw tight.

3.2.2 Mounting the hood unit

1. Open the filter panels.

2. Remove the grease filters with the

respective handles.

3. Hook the panel out of the hood unit by

moving the lever of the fastening pin.

4. Adjust the two screws (Vr) of the clamps

(11a) so that they are only screwed in

until the thread commences (B).

5. Hook the hood unit into the two clamps

(11a).

6. Align the hood unit with the Vr screws

from the inside of the hood.

7. Tighten the safety screws (11).

3.2.3 Connections

Connection of the extraction air model

The optional “outgoing air chimney” kit, spare part no. 877 must be bought for installing the exhaust air

models.

Connection of the recirculating air model

Charcoal filters, spare part no. 603, are required

for installing the recirculating air models. A cover,

spare part no. 527678 (item 16), and a grid, spare

part no. 536452 (item 8), should be installed for

better air circulation.

1. Fasten the filter cover at the air exit with the

four screws (12c) (2.9 x 9.5).

2. Fasten the air conduction grid (8) with two of

the screws supplied (12d) (2.9 x 9.5) at the

exit of the recycling air.

3. Activating the saturation display

For hoods with a recirculating air mode the

saturation display is activated on installation

or later. Switch off the lighting and the fan

motor. Disconnect the hood from the power supply at the intermediate two-pole switch or at the

main switch. Re-establish connection by pressing and holding the T1 button. Let go of the button;

all five LEDs light up consistently.

Within three seconds press the T1 button until the T1 and T4 LEDs begin to blink as

acknowledgement:

2 blinks of the LEDs – saturation display of the charcoal odour filters is ACTIVATED;

1 blink of the LEDs – saturation display of the charcoal odour filters is DEACTIVATED.

Press the T1 button until the T1 and T4 LEDs begin to blink as acknowledgement. Two blinks of

the saturation display LED indicates that the charcoal odour filters are ACTIVATED.
