FAQ Range Hoods

Topic

What actions can I take to prevent undesirable odours?

To make sure the range hood works as effectively as possible, switch it on three to five minutes before you start cooking. This allows an air flow to be established in the room so that vapours and odours can be conducted away quickly. To prevent the build-up of negative pressure and support the extraction of cooking odours, fresh air must be supplied at the same time. As a result, the following rules apply: always open a window when using air extraction solutions. Once you have finished cooking, keep the fan running for another five to ten minutes. Many range hoods have an automatic run-on function for this purpose. In particular, frying pans should be left under the range hood if they are still hot because they can still disperse odours even after you have finished cooking.

What is the automatic run-on function?

Hoods with the automatic run-on function extract the remaining cooking vapours from the room for a specific time period (between 5 and 20 minutes) even after you have finished cooking and switched off the range hood. After that point, the range hood is switched off automatically. If the appliance is being used in recirculation mode, the activated charcoal filter can also carry out final drying of the furniture base – just like in range hoods that remove vapours by extracting them downwards (downdraft systems). This useful function is integrated into various range hoods and downdraft systems, and is activated by tapping the clock button shown at the end of the cooking process.

How long will the LED lights last in my range hood?

Since 2019, all our range hoods have been equipped exclusively with energy-saving LED lights. LEDs have energy-efficient properties plus a long service life. 

Can I adjust the colour temperature for the range hood lighting?

Yes you can – various range hoods have the FlexLED function. This allows you to easily adjust the colour temperature, from a warm-white 2700 to a cool 4000 kelvin. This feature creates the perfect atmosphere in harmony with the kitchen lighting and can be individually tailored to all kinds of lighting concepts.

What should I bear in mind when planning and installing an exhaust duct?

The exhaust duct should be as short as possible and have as few bends and curves as possible. Ideally, it should have a diameter of 150 mm. Each additional metre added to the exhaust duct and each additional bend will create resistance, reducing the power of the range hood. A more powerful range hood cannot compensate for a poorly designed exhaust duct. This will only result in increased losses and noise levels. Reducing the diameter of the exhaust duct should be avoided where possible – due to the increased flow rate, this will also lead to increased noise levels.

How important is it for the range hood to cover the entire hob surface?

The more the range hood covers the hob, the better the extraction performance. This is why flat pull-out deflector plates perform very well. For wall and island hoods, you should make sure that the majority of the hob is well covered.

Can you clean the metal grease filters in the dishwasher?

All metal grease filters should be cleaned at least once every two months (more frequently in the event of intensive use, and at the latest when the noise increases). Range hoods with saturation indicators on the display remind you to clean them regularly. You can soak the metal grease filter by hand and clean it with gentle detergent. It can, of course, also be cleaned in the dishwasher – simply choose an intensive programme. If you choose to wash the filter in the dishwasher, do not place any other crockery in the dishwasher.

What is the metal grease filter saturation indicator?

Some range hoods are equipped with a warning light that shows you when the metal grease filter needs to be cleaned. The operating hours counter can be used to roughly estimate whether the metal grease filter is full or not. 

What is the difference between an extracted air and a recirculation air range hood?

Extracted air range hoods require access to the outdoors. They convey cooking vapours directly outside into the open air via the metal grease filter. In a recirculation air range hood, the air is drawn in, cleaned using an activated charcoal filter and then conveyed back into the kitchen. This option is particularly suitable if there is no way to convey the cooking vapours from the range hood in your kitchen to the outside. Virtually all V-ZUG range hoods can be operated with either extracted air or recirculation air. 

What makes the extractor hoods particularly user-friendly?

We recommend conveying the extracted air outside wherever possible, as this carries smells away from the kitchen. The most effective solution is to use an exhaust system (duct) with a diameter of 150 mm.

What types of range hoods are there?

There are different solutions to suit you – whether you want your range hood to be an eye-catching design feature or for it to be discreetly integrated into your kitchen.

On the wall 
If you want to make your range hood stand out, then a wall hood is a great choice. Wall hoods are also available as slanted versions which provide ample headroom. They are installed on the wall directly above the hob.

Integrated into the kitchen units
If you would rather incorporate the hood into the kitchen so that it is virtually invisible, then we recommend a built-in range hood with a glass canopy, a flat-panel range hood or an integrated range hood. These are perfect for kitchens in which you need to make clever use of the space.

On the ceiling
Range hoods designed for ceiling installation are the perfect solution in open-plan kitchens that feature a free-standing cooking island. Choose your favourites from our elegant ceiling range hoods and our wide range of attractive island hoods.

Downdraft or in the hob itself
Without long detours, cooking vapours are whisked away at the very place where they first develop – on the hob itself. Our integrated hob hood, the pull-out downdraft and the induction hob with integrated range hood offer increased headroom and extract the vapours downwards. 

Should I leave the windows and doors open or closed when using the range hood?

Range hoods need enough replacement air to guarantee optimum extraction performance. You can ensure this by opening a window or incorporating a replacement air unit. If there is insufficient replacement air, this can create negative pressure (a vacuum) – the range hood will become significantly louder and it will have difficulty conveying the cooking odours outside.

How often does the activated charcoal filter need to be replaced?

The activated charcoal filters can be easily removed and regenerated, depending on the model. The most efficient long-life plus activated charcoal filter, for example, can be regenerated in the oven every three to six months. The long-life activated charcoal filter can be cleaned in the dishwasher and then dried in the oven. Conventional activated charcoal filters need to be replaced every six months or so.

Is it possible to use an extracted air or a recirculation air solution in conjunction with the Fusion hob with integrated range hood?

Yes it is – the unit can be installed with either an extracted air or a recirculation air solution.

Which range hoods are particularly quiet?

The level of noise emitted by a range hood depends on the model and extracted air system chosen. In the case of extracted air range hoods, the following rule applies: the smaller the diameter of the exhaust duct, the louder the appliance. As a result, we recommend using a pipe diameter of 150 mm in extracted air mode. 

Is it a good idea to install a sound absorber with a wall/island hood or built-in range hood?

Yes, we would definitely recommend installing a sound absorber to reduce the overall noise emissions. In extracted air mode, both the fan noise going outside and the outdoor noise coming inside via the extracted air duct can be reduced. In the case of recirculation mode, the sound absorber is positioned directly on the fan nozzle in the hood flue.

What material is the ventilation duct of the DSMS hob hood made from?

The material is a flame-retardant plastic blend, which is self-extinguishing with a V0 classification as per the UL94 standard.

What does the energy efficiency category say about a range hood?

The energy efficiency category helps you to understand a range hood’s energy consumption and to compare it to others. Since the start of 2020, products have been given a rating on a scale of A+++ to D. The most energy-efficient V-ZUG range hoods are in efficiency category A++.

How do the hob hood and the hob with integrated range hood work?

Steam and odours rise at a maximum rate of one metre per second. The V-ZUG hob hood or hob with integrated range hood extracts the air using a cross current that is higher than the rising speed of the cooking vapour. As a result, cooking vapours and odours can be effectively extracted straight away at the hob.

Does the hob ventilation/hob hood ventilation also work with taller pots?

Cooking vapours can be extracted without any problems in the case of pots up to 20 cm tall. For pots that are over 21 cm tall, we recommend placing the pot lid at an angle in order to direct the steam towards the range hood. 

What do I need to consider with regard to the exhaust duct?

If possible, you should make sure that the duct diameter is at least 125 mm and ideally 150 mm. If there is no room for a round pipe, a flat channel with an equivalent cross section may also be used. The use of 90° pipe bends should be kept to a minimum. Narrowing cross sections and reducing pipes with a smooth inner surface should also be avoided. We recommend using short piping lengths, wall boxes with large slats and sufficient replacement air.
 

What do I need to know about range hoods using recirculation air?

Compared with the extracted air solution, there is much less to consider for range hoods with recirculation air, particularly if you have chimney-based heating (such as gas, oil or coal-fired heaters, flow heaters, water heaters and open fireplaces). They are easy to install and they can be operated without restrictions if the range hood is used in recirculation mode with an activated charcoal filter. To use recirculation mode, you must provide an activated charcoal filter – the filter absorbs unpleasant odours and ensures there is fresh air in the kitchen while you are cooking. 

Do I need to air the room when I use my range hood?

You should always ensure there is a supply of replacement air when the range hood is running. In the case of a recirculation air range hood, this enables air that is still moist after passing through the filters to be replaced. In extracted air solutions, an open window helps to optimise the air flow and prevents negative pressure building up in the kitchen.

oder direkt in der Brochure: "Standard-Lüftungssysteme für Wohnbauten"

What is OptiLink?

Hobs and range hoods that feature the OptiLink function communicate with each other via Bluetooth. The fan level automatically adjusts to the current cooking level and switches off automatically when the hob is switched off – so you can focus all your attention on cooking without having to think about operating the range hood. All models in the V6000 and V4000 series have this technology integrated as standard at no extra cost. 

Does every hob work with OptiLink?

To fully enjoy OptiLink, both the hob and the hood must be equipped with the OptiLink function. Look out for the "Fan wheel with chain links" symbol in the "Equipment and operating modes" section.
 

How many hobs can I connect to a range hood via Bluetooth?

Up to three hobs at the same time.

How do I connect my hob to the range hood so that I can use OptiLink?

Connecting, or pairing, your V-ZUG built-in range hood with our networkable hobs is a breeze.
 

Can I switch off/suppress the automatic light activation if I don’t really need a light above the cooking area?

For safety reasons, we recommend that the cooking area is always well lit.

Does the screen need to be pulled out on a built-in range hood for OptiLink to work?

The screen must always be pulled out to ensure the range hood can work at its best. 

Can I adjust the reaction times for the hob and range hood in OptiLink operating mode?

Three levels are available in OptiLink mode that vary in terms of their reaction times 
and the maximum possible power level.
 
Level 1: Silent mode – reaction time 60 seconds and maximum power level 2
Level 2: Standard mode – reaction time 45 seconds and maximum power level 3
Level 3: Intensive mode – reaction time 20 seconds and maximum power level Intensive
 
You can easily select whichever operating mode you want. When the appliance is switched off, press the "Light" and "Automatic run-on" buttons at the same time. The operating mode that is currently selected will be shown on the power level display. You can change the operating mode by pressing the power button. The selected setting will be saved 5 seconds after the last input.
