Frequently Asked Questions - IBE 7944 N I79E44N0 NEFF

How to install the Neff IBE 7944 N hood?

Installation must be carried out by a specialist. Respect minimum distances: 550 mm above an electric hob, 650 mm above a gas hob. The hood is mounted on the ceiling using the provided support frame. Ensure the ceiling can support a weight of 43 kg. Connect the exhaust duct (Ø 150 mm recommended) and the electrical connection to an earthed socket.

How to clean the grease filters?

The metal grease filters should be cleaned once a month to prevent fire risk. You can wash them in the dishwasher (placing them flat) or by hand with hot water and mild detergent. Never use abrasive products.

When should the charcoal filter be replaced?

The activated charcoal filter should be replaced approximately twice a year, or more frequently with heavy use. It is available from the after-sales service or online store. Use only original filters.

How to replace a bulb?

Before replacing the bulb, cut off the power and allow the bulb to cool. Gently remove the bulb ring (for halogen) or cover (for incandescent). Replace with a bulb of the same type and power (see rating plate). Do not touch the glass of the halogen bulb.

What to do if the hood does not turn on?

First check the electrical supply (socket, circuit breaker). Ensure the plug is properly inserted. If the lighting does not work, check the bulbs. If the problem persists, contact the after-sales service with the EFD number (on the rating plate after removing the filters).

What is the minimum distance between the hood and the hob?

For electric hobs: 550 mm. For gas hobs: 650 mm (measured from the top edge of the grid to the bottom edge of the hood). If using both types, respect the larger distance.

Can the hood be used in recirculation mode?

Yes, the hood can operate in air recirculation mode. In this case, you must install an activated charcoal filter (optional). The filtered air is then returned to the kitchen. The complete mounting kit is available as an accessory.

How to adjust the suction power?

Use the control buttons: press 1 for low speed, 2 or 3 for higher speeds. For temporary intensive suction (strong odors or steam), press the P button. Switch off with the 0 button.

(See list of customer service centres).

When calling, please quote:

E-no. FD

The numbers can be found on the rating plate, after removal of the grease filter, inside the extractor hood.

Enter the numbers in the above fields.

Intended use

This extractor hood complies with the stipulated safety regulations. Improper use may result in injury or damage. The extractor hood may be used in the household only. The manufacturer is not liable for damage which is caused by improper use or incorrect operation. The manufacturer cannot be made responsible for damage which can be attributed to non-observation of the safety instructions.

RISK OF INJURY

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.

Technical safety

The extractor hood left the factory in perfect condition. Nevertheless, check the appliance for visible damage before installation. If it is damaged, do not switch it on! If the power cord of the extractor hood is damaged, it must be replaced by the manufacturer, its customer service, or a similarly qualified person to prevent hazardous situations. Only a qualified technician may install (including electrical connection), service, or repair the extractor hood. Always isolate the extractor hood by pulling out the mains plug or switching off the fuse!

If the appliance is improperly installed, serviced, or repaired, the user may be placed in considerable danger for which the manufacturer is not liable. Changes to the electrical or mechanical installation are dangerous and must not be undertaken! They may also cause the extractor hood to malfunction.

Simultaneous operation of the extractor hood with a heating appliance which is dependent on ambient air

Heating appliances which are dependent on ambient air, e.g. gas, oil, wood, or solid-fuel heaters, instantaneous water heaters, hot water boilers, hobs or ovens, and which draw combustion air out of the installation room and whose exhaust gases are conveyed to the exterior by a flue.

RISK OF POISONING

If the extractor hood is operated at the same time as a heating appliance which is dependent on ambient air, there is a risk of poisoning due to combustion gases being drawn back in.

• Safe operation is possible provided the low pressure in the installation room of the heating appliance does not exceed 4 Pa (0.04 mbar). This can be achieved if the combustion air can flow through non-closable openings, e.g. in doors, windows, in conjunction with air intake/exhaust air wall boxes or by other technical measures.

Adequate intake air must therefore always be provided. An intake/exhaust air wall box alone does not ensure compliance with the limit value.

NOTE: When making your evaluation, always consider the entire ventilation system in the home. Include the advice of a competent heating engineer when making your evaluation.

If the extractor hood is used in circulating air mode only, it can be operated without any restrictions.

Special information for gas cookers

When installing the extractor hood above gas hobs, observe the appropriate national statutory regulations (e.g. in Germany: Technische Regeln Gasinstallation TRGI). Observe the currently valid installation regulations and instructions of the gas appliance manufacturer. During installation, ensure that only one side of the extractor hood is situated directly next to a high-sided unit or a wall. Otherwise, there is a risk of heat build-up. The gap between the extractor hood and the wall or high-sided unit must be at least 50 mm.

RISK OF BURNS

Do not operate more than 2 gas cooking areas simultaneously over a period of max. 15 minutes at maximum thermal load. Due to the effect of the heat there is a risk of burns if the surfaces of the housing are touched!

Note that one large burner of more than 5 kW (Wok) is equivalent to the power of 2 gas burners. The extractor hood may be damaged by the intense heat. Never operate a gas cooking area without a cooking utensil on it. Regulate the flame in such a way that it does not project over the cooking utensil.

Proper use

Clean the extractor hood thoroughly before using for the first time. Before cleaning and servicing the extractor hood, isolate it from the power supply by pulling out the mains plug or switching off the fuse. Bulbs (especially halogen bulbs) become very hot during operation. Even some time after the appliance has been switched off, there is still a risk of burns! Before changing bulbs, isolate the extractor hood from the power supply and leave the bulbs to cool down! Do not operate the extractor hood without bulbs inserted. Always switch on the extractor hood if a hotplate is being used. If the extractor hood is not switched on, condensation may form. As a result, the appliance may corrode. Do not place any objects on the extractor hood.

RISK OF FIRE

Do not flambé under the extractor hood or work with a naked flame. When switched on, the extractor hood draws flames into the filter. There is a risk of fire due to deposits on the grease filter! Do not leave pans, frying pans or deep-fat fryers unattended if you are cooking food with oils or fats, e.g. chips. Overheated oils or fats can easily ignite! A risk of fire can be prevented by cleaning the grease filters regularly and changing the activated-carbon filter in good time.

Never operate the extractor hood without grease filters.

Correct installation

Check the manufacturer's specifications for the cooker to determine whether an extractor hood can be operated over it. If the manufacturer of the cooker has not specified any significant safety distances, the following minimum distances apply

• 550 mm between electric hob and the lower edge of the extractor hood, Fig. 1.
• 650 mm between gas hob (upper edge of pan support) and the lower edge of the extractor hood, Fig. 1.

If various cookers are used, the greatest indicated distance applies. The width of the extractor hood must correspond to the width of the cooking area. The extractor hood must not be installed over a solid fuel heating appliance which may be a fire risk (e.g. flying sparks) unless the heating appliance has a closed, non-detachable cover and the country-specific regulations are observed. This restriction does not apply to gas cookers and gas hobs. To avoid damaging the hob, cover it when installing the extractor hood.

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

Exhaust-air mode

The air which is drawn in is cleaned by the grease filters and conveyed to the exterior by a pipe system.

Appliance dimensions Exhaust air

Circulating-air mode

The air which is drawn in is cleaned by the grease filters and an activated carbon filter and conveyed back into the kitchen.

An activated carbon filter must be installed to bind odours in circulating-air mode (see "Removing and installing the grease filters").

The complete installation set as well as the replacement filters are available from specialist outlets, customer service or the Online Shop. The accessory number can be found at the end of the operating instructions.

Appliance dimensions Circulating air

The description of the operation applies to several appliance models. It is possible that individual features are described which do not apply to your appliance.

Light Fan settings

LOOKING AFTER THE APPLIANCE

Suitable cleaning agents and care products for your appliance can be purchased via the Hotline or from the Online Shop (see cover page).

Appliance surfaces

NOTE: Observe the warranty regulations in the enclosed service booklet.

The appliance surfaces and controls are scratch-sensitive. Therefore observe the following cleaning instructions:

• Avoid cleaning the extractor hood with dry cloths, abrasive sponges, scouring agents, cleaning agents containing sand, soda, acid, chlorine or any other aggressive substances.
• Clean the appliance surfaces and controls with a soft, damp cloth, washing-up liquid or a mild window cleaner only.
• Do not scrape off dried dirt, but moisten with a damp cloth.
• Clean carefully in the area of the controls to avoid liquid from getting into the electronics.

NOTE: Clean the stainless steel surfaces in the direction of the ground surface only! Do not use stainless steel cleaner for the control buttons!

Metal-mesh grease filters

The metal-mesh grease filters absorb the grease particles from the kitchen fumes. The filter mats consist of fire-proof metal.

RISK OF FIRE

As the filters become more saturated with greasy residue, the flammability increases. The function of the extractor hood may also be impaired.

The risk of fire is prevented by cleaning the metal-mesh grease filters in good time. When cleaning the grease filters, also remove grease deposits from the accessible parts of the housing with a damp cloth.

Cleaning the metal-mesh grease filters ...

Under normal operation (daily 1 to 2 hours), the metal-mesh grease filters must be cleaned 1x month.

... in the dishwasher

The metal-mesh grease filters can be cleaned in the dishwasher. Slight discolouration may occur but this will not affect the function of the grease filters. The filters must be placed loosely in the dishwasher. They must not be wedged in.

NOTE: Do not clean heavily saturated metal-mesh grease filters together with utensils.

... by hand

When cleaning by hand, soak the grease filters in a hot detergent solution, brush off the dirt, rinse thoroughly and leave to dry. Do not use any aggressive, acidic or alkaline cleaning agents. If dirt is particularly stubborn, we recommend using a special grease solvent spray. This can be ordered via the Online Shop.

Before removing and installing the grease filters, always follow the instructions and warnings in the chapter entitled "Safety instructions"!

Removing and installing the metal-mesh grease filters

1. Open the lock and fold down the grease filters. In doing so, hold the underside of the grease filters with your other hand.

Defective bulbs should be replaced immediately to avoid overloading the remaining bulbs.

Prior to installation, always follow the instructions and warnings in the chapter entitled "Safety instructions"!

Exhaust-air mode

The exhaust air is conveyed upwards via a ventilation shaft or directly through the outer wall to the exterior.

NOTE: The exhaust air must not be conveyed into a functioning smoke or exhaust gas flue or into a shaft which is used to ventilate installation rooms which contain heating appliances.

Before conveying the exhaust air into a non-functioning smoke or exhaust gas flue, obtain the consent of the appropriate heating engineer. Discharge exhaust air in accordance with the official and statutory regulations (e.g. regional building laws). If the exhaust air is conveyed through the outer wall, a telescopic wall box should be used.

To ensure optimum performance, the extractor hood requires:

• a short, straight exhaust air pipe and
• the largest possible pipe diameter. If pipe bends cannot be avoided, ensure the largest possible radii. NOTE: If long, rough exhaust air pipes, a lot of pipe bends or pipe diameters less than 150 mm are used, the air capacity will be less than optimum and there will be an increase in noise. Use only pipes or hoses made of noncombustible material for installation of the exhaust air duct. The manufacturer of the extractor hoods is not responsible for complaints which can be attributed to planning and design of the pipework.

Connecting pipes

The diameter of the exhaust air pipes should not be less than 150 mm.

Round pipes:

We recommend an inner diameter of 150 mm, however at least 120 mm.

Flat ducts must have the same inner cross-section as round pipes.

There should be no sharp bends.

0 150 mm approx. 177 cm² 0 120 mm approx. 113 cm²

If pipe diameters differ:

Use sealing strips.

Connection of 150 mm Ø exhaust air pipe (recommended size)
