Operation Instructions

Operating modes

Exhaust-air mode:

The extractor-hood fan extracts the kitchen vapours and conveys them through the grease filter into the atmosphere.

The grease filter absorbs the solid particles in the kitchen vapours.

The kitchen is kept almost free of grease and odours.

Circulating-air mode

An activated carbon filter must be fitted for this operating mode (see Filters and maintenance).

Activated carbon filters can be purchased from specialist outlets

(see Optional accessories on the last page).

The ventilator fan draws the vapours produced during cooking into the extractor hood, where they pass through the grease filter and the activated carbon filter before the clean air is discharged back into the kitchen.

The grease filter absorbs the grease contained in the vapours produced during cooking.

The activated carbon filter absorbs any odorous substances.

DWhen the extractor hood is operated in exhaust-air mode simultaneously with a different burner which also makes use of the same chimney

(such as gas, oil or coal-fired heaters, continuous-flow heaters, hot-water boilers) care must be taken to ensure that there is an adequate supply of fresh air which will be needed by the burner for combustion.

Safe operation is possible provided that the underpressure in the room where the burner is installed does not exceed 4 Pa (0.04 mbar).

This can be achieved if combustion air can flow through non-lockable openings, e.g. in doors, windows and via the air- intake/exhaust-air wall box or by other technical measures, such as reciprocal interlocking, etc.

If the air intake is inadequate, there is a risk of poisoning from combustion gases which are drawn back into the room.

An air-intake/exhaust-air wall box by itself is no guarantee that the limiting value will not be exceeded.

Note: When assessing the overall requirement, the combined ventilation system for the entire household must be taken into consideration. This rule does not apply to the use of cooking appliances, such as hobs and ovens.

Unrestricted operation is possible if the extractor hood is used in recirculating mode – with activated carbon filter.

Before using the first time

Important notes:

The Instructions for Use apply to several versions of this appliance. Accordingly, you may find descriptions of individual features that do not apply to your specific appliance.

This extractor hood complies with all relevant safety regulations.

Repairs should be carried out by qualified technicians only.

Improper repairs may put the user at considerable risk.

Do not use the appliance if damaged.

The appliance may be connected to the mains by a qualified technician only.

Do not allow children to play with the extractor hood! Adults and children must never operate the appliance unsupervised

–if they are not physically or mentally capable of doing so,

–or if they do not have the knowledge and experience to operate the appliance correctly and safely.

If the connecting cable for this appliance is damaged, the cable must be replaced by the manufacturer or his customer service or a similarly qualified person in order to prevent serious injury to the user.

Dispose of packaging materials properly (see Installation instructions).

This extractor hood is designed for domestic use only.

Light bulbs must always be fitted when the extractor hood is in use.

Defective bulbs should be replaced immediately to prevent the remaining bulbs from overloading.

Never operate the extractor hood without a grease filter.

Overheated fat or oil can easily catch

fire.

If you are cooking with fat or oil, e.g. chips, etc., never leave the cooker unattended.

Do not flambé food directly under the extractor hood.

!Risk of grease filter catching fire due to flames.

Before using your appliance for the first time, please read these Instructions for Use carefully. They contain important information concerning your personal safety as well as on use and care of the appliance.

Please retain the operating and installation instructions for a subsequent owner.

The hotplates must always be covered with a utensil.

Restrictions apply to the use of the extractor hood over a solid-fuel burner (coal, wood, etc.). (See Installation instructions).

Gas hobs / Gas cookers

Do not use all the gas hotplates simultaneously for a prolonged period (max. 15 minutes) at maximum thermal load, otherwise there is a risk of burns if the housing surfaces are touched or a risk of damage to the extractor hood. If the extractor hood is situated over a gas hob, operate the hood at maximum setting if three or more gas hotplates are operated simultaneously.

If no activated carbon filter is installed, it is not possible to bind the odorous substances in the cooking vapours.

The filter can be cleaned in a dishwasher.

This can however cause slight discoloration.

If you encounter a problem

If you have any questions or if a fault occurs, please call Customer Service.

(See list of Customer Service representatives).

When you call, please quote the following:

E-Nr. FD

Enter the relevant numbers into the box above. The E-Nr. (product no.) and FD (production date) are shown on the nameplate which can be seen inside the extractor hood after the filter frame has been detached.

How to operate the extractor hood

The most effective method of removing vapours produced during cooking is to:

Switch the ventilator ON

as soon as you begin cooking.

Switch the ventilator OFF

a few minutes after you have finished cooking.

Filters and maintenance

Various types of grease filter can be used to absorb the grease contained in the vapours produced during cooking.

Fleece grease filter

The filter mat is made from material that is itself virtually non-inflammable.

Caution:

As it becomes more and more saturated with grease however, the filter becomes increasingly inflammable. The efficiency of the extractor hood can also be adversely affected.

Important:

Renewing the fleece filter at appropriate intervals prevents the possibility of it catching fire as a result of a build-up of heat, such as occurs when deep-fat frying or roasting is taking place.

Renewing the fleece filter:

Under normal operating conditions (1 to 2 hours per day), the fleece filter will require replacing after 8 to 10 weeks. Printed fleece filters must be

renewed no later than when the coloured printing has started to fade.

Use only original replacement filters.

In so doing you will ensure that safety regulations are upheld and the extractor hood performs as effectively as possible.

Disposing of the old fleece grease filter:

Fleece grease filters do not contain any pollutants. They can be composted and disposed of as biodegradable waste.

Metal grease filter

The filter mat is made of non-combustible metal.

Caution:

As it becomes more and more saturated with grease, the filter also becomes increasingly inflammable. The efficiency of the extractor hood can also be adversely affected.

Important:

Clean the metal grease filter at regular intervals.

Cleaning the metal filter:

Under normal operating conditions (1 to 2 hours per day), the metal grease filter will

require cleaning after 8 to 10 weeks.

Filters and maintenance

Important:

Metal filters that are heavily saturated with grease should not be cleaned at the same time as any crockery, etc.

If the filter mat is going to be cleaned by hand, soak it first of all in a hot detergent solution for several hours.

Clean the filter with a brush, rinse it off thoroughly and allow it to drip dry.

Use only original replacement filters.

In so doing you will be ensuring that the extractor hood performs as effectively as possible.

Removing and installing the grease filter

Extractor hoods with a filter mat:

1. Rotate the handles on the left and right of the filter grille.

Extractor hoods with two filter cartridges:

Warning: The halogen bulbs must be switched off and cool.

1.Depress the detent on the grease filters in the direction of the arrow and fold down the grease filter slightly. Detach the grease filter by pulling it towards yourself.

2. Press the retaining spring and remove the filter frame.

2. Clean the grease filters.

3. Re-insert the clean grease filters.

3.Remove the wire grille and replace the filter mat.

4.Install the filter frame in reverse sequence.

Re-attach the retaining spring.

The left and right sides of the filter frame must lock into position!

Activated carbon filter

Removing and installing the activated carbon filter

Extractor hoods with a filter mat:

1.Remove the filter; see grease filter.

The wire grille is no longer required when an activated carbon filter is installed.

2.Place the activated carbon filter on the filter mat and clamp it in.

3.Install the filter frame.See grease filter.
