Operating instructions:

Description of appliance

Switch/light/ fan Light Filter grille

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.

If the extractor hood is operated in exhaust-air mode at the same time as a flue-type heater (e.g. gas, oil or solid-fuel heater, instantaneous water heater, boiler), ensure that there is an adequate air supply which the heater requires for combustion.

Safe operation is possible provided that the partial vacuum in the room in which the heater is installed does not exceed 4 Pa (0.04 mbar).

This can be achieved if the combustion air is able to flow through non-lockable openings, e.g. in doors, windows and in conjunction with an air supply/air-intake wall box or by other technical procedures such as reciprocal interlocking.

Operating modes

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.

Circulating-air mode:

☐ An activated carbon filter must be fitted for this operating mode (see Filters and maintenance). The activated carbon filter can be purchased as an optional accessory FROM YOUR DEALER. The corresponding accessory numbers can be found at the end of these operating instructions.
☐ The extractor-hood fan extracts the kitchen vapours which are purified in the grease filter and activated carbon filter and then conveyed back into the kitchen.
☐ The grease filter absorbs the grease particles in the kitchen vapours.
☐ The activated carbon filter binds the odorous substances.

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

⚠️ If the extractor hood is switched from exhaust-air mode to circulating-air mode, the exhaust-air opening must be sealed to prevent a hazardous situation (see optional accessories in the Instructions for use).

Filters and maintenance

Grease filters:

Metal filters are used to trap the greasy element of the vapours that develop during cooking.

The filter mats are made from non-combustible metal.

Caution:

As the filter becomes more and more saturated with grease, not only does the risk of it catching fire increase but the efficiency of the extractor hood can also be adversely affected.

Important:

By cleaning the metal grease filters at appropriate intervals, the possibility of them catching fire as a result of a build-up of heat such as occurs when deep-fat frying or roasting is taking place, is reduced.

Cleaning the metal grease filters:

☐ In normal operation (1 to 2 hours daily), the metal grease filter must be cleaned after 8 to 10 weeks.
☐ The filters can be cleaned in a dish-washer. It is however possible that they will become slightly discoloured.
☐ The filter must be placed loosely, and NOT wedged, in the dishwasher.

Important:

Metal filters that are saturated with grease should not be washed together with other dishes etc.

☐ When cleaning the filters by hand, soak them in hot soapy water first of all.

Then brush the filters clean, rinse them thoroughly and leave the water to drain off.

Removing and inserting the metal grease filters:

1. Press the catch on the grease filters inwards and fold the filters down.

Replacing the activated carbon filter:

☐ During normal operation (daily 1 to 2 hours) the activated carbon filter must be replaced approximately 1 x year.

☐ The activated carbon filter can be purchased FROM YOUR DEALER (see Optional accessories).

□ Use only original filters.

These ensure optimum function.

Disposal of the old activated carbon filter:

□ Activated carbon filters do not contain any harmful substances. They can be disposed of as residual waste.

Cleaning and care

Isolate the extractor hood by pulling out the mains plug or switching off the fuse.

☐ When cleaning the grease filters, remove grease deposits from accessible parts of the housing. This prevents the risk of fire and ensures that the extractor hood continues operating at maximum efficiency.
□ Clean the extractor hood with a hot soap solution or a mild window cleaner.
☐ Do not scrape off dried-on dirt but wipe off with a damp cloth.
☐ Do not use scouring agents or abrasive sponges.
☐ Note: Do not use alcohol (spirit) on plastic surfaces, as dull marks may appear.

Caution: Ensure that the kitchen is adequately ventilated. Avoid naked flames!

⚠ Clean the operating buttons with a mild soapy solution and a soft, damp cloth only. Do not use stainless-steel cleaner to clean the operating buttons.

Stainless steel surfaces:

□ Use a mild non-abrasive stainless steel cleaner.
□ Clean the surface in the same direction as it has been ground and polished.
Do not use any of the following to clean stainless steel surfaces: abrasive sponges, cleaning agents containing sand, soda, acid or chloride!

Aluminium and plastic surfaces:

□ Use a soft, non-linting window cloth or micro-fibre cloth.
□ Do not use dry cloths.
□ Use a mild window cleaning agent.
☐ Do not use aggressive, acidic or caustic cleaners.
☐ Do not use abrasive agents.

Replacing the light bulbs

1. Switch off the extractor hood and isolate the extractor hood by pulling out the mains plug or switching off the fuse.
2. Remove the grease filter (see Filters and maintenance).

Important information

⚠️ Old appliances are not worthless rubbish. Valuable raw materials can be reclaimed by recycling old appliances. Before disposing of your old appliance, render it unusable.

⚠️ You received your new appliance in a protective shipping carton. All packaging materials are environmentally friendly and recyclable. Please contribute to a better environment by disposing of packaging materials in an environmentally-friendly manner.

Please ask your dealer or inquire at your local authority about current means of disposal.

⚠ The extractor hood can be used in exhaust air or circulating air mode.

⚠️ Always mount the extractor hood over the centre of the hob.

⚠️ Minimum distance between electric hob and bottom edge of extractor hood: 650 mm, Fig. 1.

Additional information concerning gas cookers:

⚠ When installing gas hotplates, comply with the relevant national statutory regulations (e.g. in Germany: Technische Regeln Gasinstallation TRGI).

⚠️ Always comply with the currently valid regulations and installation instructions supplied by the gas appliance manufacturer.

⚠️ Only one side of the extractor hood may be installed next to a high-sided unit or high wall. Gap at least 50 mm.

⚠ The installation of the extractor hood above gas cooking devices, at a minimum height of 650 mm – Fig. 1 – is permitted provided that the following nominal heat loads (Hs) are not exceeded:

☐ Gas cookers Load of one hotplate max. 3.0 kW Load of all hotplates max. 8.3 kW Load of the oven max. 3.9 kW

☐ Gas hobs Load of one hotplate max. 3.9 kW Load of all hotplates max. 11.3 kW

☐ Gas ceramic hotplate The nominal heat load specifications do not apply to closed gas ceramic hobs. Always observe the specifications of the hob manufacturer.

☐ Solid-fuel cookers The maximum nominal heat loads and the minimum distance are the same as for gas cookers.

⚠ The extractor hood may only be installed over a fireplace which burns solid fuel (fire hazard due to flying sparks) if the fireplace has a closed, non-detachable cover and national regulations have been observed. This restriction does not apply to gas cookers and gas hobs.

⚠ The smaller the gap between the extractor hood and hotplates, the greater the likelihood that droplets will form on the underside of the extractor hood.

Exhaust-air mode

The exhaust air is discharged upwards through a ventilation shaft or directly through the outside wall into the open.

Exhaust air must not be discharged via a smoke or exhaust gas flue which is already in use or via a shaft which is used for ventilating rooms in which fireplaces are located.

Discharge exhaust air in accordance with official and statutory regulations (e.g. national building regulations).

Discharge of air into smoke or exhaust air flues which are not in use requires the consent of a heating engineer.

If the extractor hood is operated in exhaust-air mode at the same time as a flue-type heater (e.g. gas, oil or solid-fuel heater, instantaneous water heater, boiler), ensure that there is an adequate air supply which the heater requires for combustion.

Safe operation is possible provided that the partial vacuum in the room in which the heater is installed does not exceed 4 Pa (0.04 mbar).

This can be achieved if the combustion air is able to flow through non-lockable openings, e.g. in doors, windows and in conjunction with an air supply/air-intake wall box or by other technical procedures such as reciprocal interlocking.
