1. Why we need a cooker hood in the kitchen?

The kitchen cooker hood (absorber) removes the unpleasant smells, vapour and smoke originated during the cooking making the atmosphere more pleasant and comfortable. It is irreplaceable helper for the contemporary housewife because it not only purifies the air in the kitchen but  prevents the precipitation of fat particles on the furniture as well as the formation of condense in the kitchen.

2. Extraction hood or recycling hood?

In the extraction working mode the vapors and unpleasant smells are expelled to the duct, ventilation shaft of the building or directly to the atmosphere.  In this case the appliance is called “extraction hood”. 
In the recycling working mode (recycling version) usually there is no possibility for expelling fumes and steams out of the kitchen and therefore it turns to putting charcoal filters inside the hood which purify the air.  The recycled air returns to the kitchen. All FABER and EUROLUX BY FABER  hoods can be completed with charcoal filters.
From both working modes the first one (extraction version) is advisable because the hood reaches its full capacity in it.  The appliance reduces its capacity by 25% working on charcoal filter. Moreover,  the charcoal filter is consumable which must be changed after fixed periods of time depending on the intensity of the hood's usage

3. How to install the hood properly?

As the cooker hood is designed to absorb the vapours, it is recommended it to be fitted at a distance not less than 60 cm and not more than 65 cm over the cooking hob. For gas appliances the minimal distance is 65 cm, the maximal – 70 cm. It is necessary the optimal distance to be observed in order to protect the grease filters from catching fire which results in a damage of diffuser group, lighting, etc.
It is important to be considered that the smoke duct must be maximally close to the the cooker hood: it is recommended the duct to be with a diameter of 150 mm with permissible reduction up to Ø120 mm. A back draught damper is mounted on the hood's outlet which prevents the unpleasant smells to be returned back in the kitchen when the outlet is connected to the general duct of the building. The back draught damper is not fitted in the case when the cooker hoods is working with charcoal filters

4.How to prevent the increasing of the hood's noise level?

The noise level, which the cooker hoods concretely generate during operation, is measured in decibels and is different at every working speed. That's why the users must be informed not only for the noise level at the minimal speed of aspiration but also for the decibels originated at every next speed in order to be guaranteed their calmness and silence.
An important condition, when a  cooker hood is chosen, is the noise level generated by the appliance to be measured according to European Norms EN 60704-3 which is the only one of its kind of international specification for studying the real noise levels when the hood is operating.
Opposed to the logic, the source of the noise in a hood is determined by the air flow which is sucked in during the hood's operation. The internal components of FABER and Eurolux by Faber hoods are made so that they do not obstruct the air flow in its way. By this way excellent results are achieved in terms of efficiency and noise level. An useful expedient to avoid excessive noise levels is utilization of outlet ducting with the larger diameters (120 – 150 mm). Of course, hood becomes more noiseless thanks also to the innovative technologies patented by FABER. An undoubted evidence for that is the SILENCE KEY – the revolutionary noise reducing system, able to reduce the noise level up to 43 dB(A) at the capacity of 450 m³/h and up to 59 dB(A) at the capacity 900 m³/h which makes the operation 16 times more silent than this one of a standard hood  without such system.

5.How to choose a cooker hood with the right capacity?

The capacity is the most important parameter of a cooker hood. Its definition is: the air flow in cubic meters that the hood can extract within 1 hour through a duct long 1 linear meter + a bend at 90º + a linear meter more. All values for the capacity indicated in the trade catalogue of LEKS GROUP are measured on the basis of such airway.
ATTENTION! The aspiration capacity of FABER and Eurolux by Faber hoods is measured in accordance with the European Norm EN 61591 studying the real capacity of suction when the  kitchen hood is in operation. In practice besides the capacity measured in accordance with the international standard also the definitions as “capacity at free outlet” and “maximal capacity”. However, these definitions are only theoretical ones, as they cannot be applied to the real use of the hood. In order to be effective, the cooker hood should be able to change the air 10 times per hour. The capacity is chosen on the basis of the kitchen volume.Depending on the sizes of the room the hood's capacity is calculated by the following formula:

square surface of the kitchen x height of the kitchen x 10 = aspiration capacity necessary for 10 changes of air within a hour.

 

Example: A kitchen with the square surface of 20 m² and height 2,6 m requires a hood which aspirate at least 520 m³/h as 20 m² x 2,6 m x 10 = 520 m³/h.

 
IMPORTANT! If there is a permanently opened connection with another room, the total square surface is determinant for choosing the necessary efficiency. Hoods with a big capacity – 900 and 1000 m³/h can be installed in small rooms only if exchange opening is provided. Thanks to that exchange opening the entry of clean air in the kitchen is guaranteed, which prevents formation of low pressure and helps for more effective operation of the hood.

6.What size of cooker hood I need?

Usually the cooker hoods are with standard width of 60, 90 and 120 cm in order to suit to all kitchen. As a general rule, the width of the cooking hob must be not wider than this one of the cooker hood.  Example: If the cooking top area is long 70 cm, it is recommended to buy a cooker hood of 90 cm.

7.What is required to obtain the maximal effectiveness of the filters?

FABER's metal cassette filters ensure very good capture of grease particles containing in the vapours sucked by the cooker hood protecting in this way its motor.
In order to purify the air effectively , the filters must be washed in a dishwasher or manually in a hot water with a detergent at every 2 months on the average (depending on the intensity of cooking). The metal filters must not be treated with products not suitable for aluminium.  They can be refitted up completely washed and dried. For maximal convenience, the new FABER models and these ones branded Eurolux by Faber are equipped also with an indication for saturated filters which signalizes when the grease filter needs to be washed and when the charcoal filter must be replaced

8.How to clean the cooker hood and what cleaners to use?

The shining of your appliances depends on their perfect surface. In order the surface to be always protected all you need is a soft cloth and a neutral detergent that is chlorine-free in order to avoid damaging the finishing, mostly of the inox models.   
CLIN & CLIN is a new product developed by FABER for cleaning the inox surfaces of the cooker hoods. CLIN & CLIN  is a single-use cloth impregnated with special oils which forms a special protective film on the surface protecting it in this way. Only with one cloth monthly you can maintain your appliances perfectly clean and shining. For removing different impurities, dust and finger prints, it is recommended also the usage of;
 WURTH spray for cleaning and maintenance
 Cleaning paste CLIN & CLIN
Thanks to these products you can always maintain all inox surfaces in your kitchen in perfect state

9.Is it possible the hood's internal surface to be cleaned?

Thanks to the patented system Easy Dismount the cooker hood's inside can be maintained in a perfect condition without a technician's intervention to be necessary. The motor groups are easy  to be dismounted. The rotors can be also removed ensuring an easy access for cleaning the air outlet. The rotors can be washed quickly manually or in a dishwasher.
The internal joins of the canopy are smooth-finished to make sure that they are not sharp and dangerous when cleaning inside the hood. Unlike ordinary switches, Faber's electronic controls   are completely safety, avoiding creation of any sparks. Tempered glass is used so that in case of accidents the glass shatters into the pieces with smooth edges.Thanks to the system Easy Dismount, the removing of all fat tracks is easy as a child play, which makes the hood more reliable and safety

10.How to use the cooker hood of full value?

The modern kitchen, more often and often, is not differentiated as a separate premises turning into functional unification of kitchen, dining-room and living-room. In this case the presence of a good cooker hood is obligatory as it not only eliminates the unpleasant smells but also prevents the grease particles' deposition on the kitchen furniture as well as the formation of condense in the room. That's why it is necessary to be well grounded in the optimal cooker hood's use in the home.        
 
1. The cooker hood must be turned on about a minute before starting to cook.
2. It is recommended the hood's operation to continue about 10 minutes after the end of the cooking. Thus the residual smells are removed from the room: the inside of the hood and air ducts are dried; the formation of condense in the recycling mode is prevented and the charcoal filter (if there is any) is dried too.
3. The charcoal filter is a consumable unit which must be replaced after certain period of time depending on intensity of cooking – at every 2, 3 or 4 months.
4. It is important the entry of clear air in the kitchen to be provided which prevents from formation of low pressure in the room making the hood's operation worse (compensation opening).
5. The hood's air duct must not be connected to exhaust ducts carrying combustion fumes (stoves, fireplaces) and to air-shaft for baths and toilets.
6. It is not recommended the building of fireplaces in the rooms where a cooker hood is mounted.
7. The greases and vapours are captured and retained by the filters every model of cooker hoods is equipped with. In order to operate effectively these filters, they must be cleaned once at every 2 months at least depending on the intensity of the cooking
