SAFETY INSTRUCTIONS

READ ALL INSTRUCTIONS BEFORE USE
The following safety guidelines are intended to prevent unforeseen risks or damage from unsafe or incorrect operation of the appliance. The guidelines are separated into ‘WARNING’ and ‘CAUTION’ as described below.

Safety Messages
This symbol is displayed to indicate matters and operations that can cause risk. Read the part with this symbol carefully and follow the instructions in order to avoid risk.
WARNING
This indicates that the failure to follow the instructions can cause serious injury or death.
CAUTION
This indicates that the failure to follow the instructions can cause the minor injury or damage to the product.

WARNING

• To reduce the risk of explosion, fire, death, electric shock, injury or scalding to persons when using this product, follow basic precautions, including the following:

Installation

• This appliance is to be properly installed and earthed only by a suitably qualified person.

• Follow the local laws applicable for external air evacuation.

• The manufacturer will not be held liable for any damages resulting from incorrect or improper installation.

• The minimum safety distance between the cooker top and the range hood is 650 mm.

• If the instructions for installation for the gas hob specify a greater distance specified above, this has to be taken into account.
  Regulations concerning the discharge of air have to be fulfilled.

• Check that the mains voltage corresponds to that indicated on the rating plate fixed to the inside of the range hood.

• Check that the domestic power supply guarantees adequate earthing.

• Connect the range hood to the exhaust flue through a pipe of minimum diameter 150 mm. The route of the flue must be as short as possible.

• Do not connect the range hood to exhaust ducts carrying combustion flumes (boilers, fireplaces, etc.).

• If the range hood is used in conjunction with non-electrical appliances (e.g. gas burning appliances), a sufficient degree of aeration must be guaranteed in the room in order to prevent the backflow of exhaust gas. The kitchen must have an opening communicating directly with the open air in order to guarantee the entry of clean air. When the range hood is used in conjunction with appliances supplied with energy other than electric, the negative pressure in the room must not exceed 0.04 mbar to prevent fumes being drawn back into the room by the range hood.

• Children may put packaging material over their heads or wrap themselves up in it and suffocate. Keep packaging material away from children. Do not let children play with packaging material.

• Children may breathe in or swallow small parts, causing them to suffocate. Keep small parts away from children. Do not let children play with small parts.

• The air must not be discharged into a flue that is used for exhausting fumes from appliances burning gas or other fuels.

• Do not install the range hood near a heat producing appliance for solid fuel (e.g.wood or coal) unless a closed, nonremovable cover is available. There must be no flying sparks.

• Observe ‘INSTALLATION’ when installing the appliance.

Operation

• The range hood has been designed exclusively for domestic use to eliminate kitchen smells.
• Never use the range hood for purposes other than for which it has been designed. The range hood is for home use only, not suitable for barbecue, roast shop and other commercial purposes.
• Never subject the hood to any naked flames that might unintentionally occur from foods being cooked on the hob below it or at any other time.
• Adjust any gas burner flame onto the bottom of the pan only, making sure that it does not engulf the sides.
• Deep fryers must be continuously monitored during use: overheated oil can burst into flames.
• Do not apply any flame to the range hood; risk of fire. Grease deposits in the grease filter may catch fire. Never work with naked flames close to the appliance (e.g. flambéing).
• This appliance can be used by children aged from 8 years and above and persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge if they have been given supervision or instruction concerning use of the appliance in a safe way and understand the hazards involved.
• Children should be supervised to ensure that they do not play with the appliance.
• There shall be adequate ventilation of the room when the range hood is used at the same time as appliances burning gas or other fuels.
• Accessible parts may become hot when used with cooking appliances. Never touch hot parts. Keep children at a safe distance.
• Hot oil and fat can ignite very quickly. Never leave hot fat or oil unattended. Never use water to put out burning oil or fat. Switch off the hotplate. Extinguish flames carefully using a lid, fire blanket or something similar.
• When gas burners are in operation without any cookware placed on them, they can build up a lot of heat. A range hood installed above the cooker may become damaged or catch fire. Only operate the gas burners with cookware on them.
• Operating several gas burners at the same time gives rise to a great deal of heat. A range hood installed above the cooker may become damaged or catch fire. Never operate two gas burners simultaneously on the highest flame for longer than 15 minutes. One large burner of more than 5 kW (wok) is equivalent to the power of two gas burners.
• Components inside the appliance may have sharp edges. Wear protective gloves when cleaning the filters and never disassemble the appliance for maintenance or repairs.
• Items placed on the appliance may fall down. Do not place any objects on the appliance.
• The light emitted by LED lights is very dazzling, and can damage the eyes (risk group 1). Do not look directly into the switched on LED lights for longer than 100 seconds.
• Plug the power cord to a suitable and matching voltage socket outlet with earthing continuity terminal. appliance has been designed to operate from a mains grid power supply.
• Use the unit according to the instructions to avoid any fire hazard.
• Never operate the appliance without a grease filter.

Maintenance

• Do not repair or replace any part of the appliance unless specifically recommended in the manual. All other servicing should be done by a qualified technician.
• Cleaning and user maintenance shall not be made by children without supervision.
• There is a fire risk if cleaning is not carried out in accordance with the instructions.
• Switch off or unplug the appliance from the mains supply before carrying out any maintenance work.
• Clean and/or replace the filters after the specified time period (to avoid a fire).
• Fatty deposits in the grease filter may catch fire. Regularly clean the grease filter.
• Prior to any maintenance, cleaning operation, ensure the power is cut off. Penetrating moisture may cause an electric shock. Do not use wet sponge cloths or flammable liquid cleaning solutions.
• If the supply cord is damaged, it must be replaced by the manufacturer, service agent or similarly qualified person in order to avoid a hazard. The replaced power cord should be provided by manufacturer or seller.
• If faulty, the appliance must not be used. If a fault occurs, the appliance must be isolated by removing the mains plug or switched off by removing the fuse or turning off the circuit breaker in the house fuse box.
