Frequently Asked Questions - DWB063451 BOSCH

How do I install the Bosch DWB063451 range hood?

Installation should be done by a qualified professional. Ensure the hood is mounted at least 65 cm above electric cooktops and 76 cm above gas cooktops. Use the provided template for drilling holes and secure with screws. Connect to a 220-240 V power outlet.

How often should I clean the grease filters?

Clean the aluminum grease filters every 2 months or when the filter saturation indicator lights up. Remove the filters and wash them in a dishwasher or by hand with warm soapy water. Allow to dry completely before reinserting.

Can I use the range hood in recirculation mode?

Yes, but you need to install an activated carbon filter (optional accessory). This filters odors and returns air to the kitchen. Follow the manual for installation instructions.

What is the maximum noise level of the hood?

The maximum noise level is 65 dB(A) at the highest speed. At lower speeds, it operates more quietly. Use the intensive speed for short periods to reduce noise.

How do I replace the LED lights?

LED lights are integrated and should only be replaced by a qualified technician. If a light fails, contact Bosch customer service for assistance.

Why is my range hood not extracting properly?

Check if the grease filters are clean. Ensure the duct is not blocked or kinked. Also, verify that the carbon filter (if used) is not saturated. If the problem persists, check the power settings and consult the manual.

How do I reset the filter saturation indicator?

After cleaning or replacing the filters, press and hold the filter reset button (usually a button with a filter icon) for about 3 seconds until the indicator light turns off.

What are the recommended safety distances?

Minimum distance between the hob and the range hood is 65 cm for electric hobs and 76 cm for gas hobs. Follow local regulations and the installation manual for exact requirements.

Can I operate the hood without a duct?

Yes, in recirculation mode with an activated carbon filter. The hood will filter and recirculate air back into the kitchen. Ensure the carbon filter is replaced every 6-12 months.

What type of grease filter does the DWB063451 use?

It uses washable aluminum grease filters. They can be cleaned in a dishwasher at 65°C. Ensure they are completely dry before reinstalling to prevent odors.

Description of appliance Operating modes

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-in-take wall box or by other technical procedures such as reciprocal interlocking.

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 complete installation set and replacement filters can be obtained from specialist outlets.
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.

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.

as soon as you begin cooking.

☐ Switch the ventilator OFF

a few minutes after you have finished cooking.

Key	Function
A	Switches the extractor motor on and off at low speed.
B	Medium speed
C	Maximum speed
D	Switches the lighting system on and off.

Grease filters:

Metal-mesh filters are used to trap the grease particles in the cooking vapours.

The filter mats are made from noncombustible metal.

Caution:

As the filter becomes more and more saturated with grease, there is an increased risk of fire and the function of the extractor hood may be impaired.

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.

Filters can be washed in the dish machine. The filters must be cleaned every 2 months of operation, or more frequently for particularly heavy usage, and can be washed in a dishwasher.

Removing and inserting metal self-supporting grease filters

☐ Remove the filters one at a time by pushing them towards the back of the group and pulling down at the same time.
☐ Wash the filters, taking care not to bend them. Allow them to dry before refitting.
☐ When refitting the filters, make sure that the handle is visible on the outside.

Filters and maintenance

Activated carbon filter:

For neutralizing odours in recirculating mode.

Caution:

As the filter becomes more and more saturated with grease, there is an increased risk of fire and the function of the hood may be impaired.

Important:

Change the activated carbon filter promptly to prevent the risk of fire from the accumulation of heat when deep-fat frying or roasting.

Replacing the activated charcoal filter

☐ The filter is not washable and cannot be regenerated, and must be replaced approximately every 4 months of operation, or more frequently for particularly heavy usage.
☐ Remove the metal grease filters.
☐ Remove the saturated activated carbon filter by releasing the fixing hooks.
☐ Fit the new filter by hooking it into its seating.
☐ Refit the metal grease filters.

Disposal of the old activated carbon filter:

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

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.
The extractor hood must not be installed over a solid fuel cooker – a potential fire hazard (e.g. flying sparks) – unless the cooker features a closed, non-removable cover and all national regulations are observed.
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.

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.
⚠️ Minimum distance on gas hotplates between the upper edge of the trivet and lower edge of the extractor hood: 650 mm.

Exhaust-air mode

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

Exhaust air should neither be directed into a smoke or exhaust flue that is currently used for other purposes, nor into a shaft that is used for ventilating rooms in which stoves or fireplaces are also located.

Exhaust air may be discharged in accordance with official and statutory regulations only (e.g. national building regulations).

Local authority regulations must be observed when discharging air into smoke or exhaust flues that are not otherwise in use.

When 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 under-pressure 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 airintake/ 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.

If the exhaust air is going to be discharged into the open, a telescopic wall box should be fitted into the outside wall.

For optimum extractor hood efficiency:

☐ Short, smooth air exhaust pipe.
☐ As few bends in the pipe as possible.
☐ Diameter of pipe to be as large as possible and no tight bends in pipe.

If long, rough exhaust-air pipes, many pipe bends or smaller pipe diameters are used, the air extraction rate will no longer be at an optimum level and there will be an increase in noise.

The manufacturer of the extractor hoods accepts no liability for complaints which can be attributed to the design and layout of the pipework.

Prior to installation

Round pipes:

We recommend

Internal diameter: 150 mm (at least 120 mm).

☐ Flat ducts must have an internal crosssection that equates to that of round pipes.
