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
WARNING
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.
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.

SAFETY INSTRUCTIONS
• 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.

5
SAFETY INSTRUCTIONS
ENGLISH
• 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. The appliance uses 4 hob elements at most.
• 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 leave high naked flames under the range hood when it is in
operation.
• Adjust the flame intensity to direct it onto the bottom of the pan only,
making sure that it does not engulf the sides.
• Deep fat fryers must be continuously monitored during use:
overheated oil can burst into flames.
• Do not flame under 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

6
SAFETY INSTRUCTIONS
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.
• 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 socket outlet with earthing continuity
terminal.
• 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.

7
SAFETY INSTRUCTIONS
ENGLISH
• Clean and/or replace the filters after the specified time period (Fire
hazard).
• 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.
• 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 the plug or cord is damaged, contact an LG Electronics Customer
Information Centre.
CAUTION
CAUTION
• To reduce the risk of injury to persons, malfunction, or damage to the
product or property when using the appliance, follow basic safety
precautions, including the following:
Maintenance
• Do not use corrosive detergent for cleaning. The proper function of
the unit is conditioned by the regularity of the maintenance.
• If there is any fault occurred with the appliance, contact an LG
Electronics Customer Information Centre.
• The grease filters may become damaged if they are squeezed. Do not
squeeze the grease filters.
Disposal
• Used appliances must be rendered unusable prior to disposal so that
they no longer present a risk. To achieve this, disconnect from the
mains supply and remove the power supply cable.

8
SAFETY INSTRUCTIONS
• For the protection of the environment, used appliances must be
disposed of properly.
• Your local City Council will inform you of times for collecting special
waste or identify public disposal facilities for you.
CARING FOR THE ENVIRONMENT
Disposal of Your Old Appliance
• This crossed-out wheeled bin symbol indicates that waste
electrical and electronic products (WEEE) should be
disposed of separately from the municipal waste stream.
• Old electrical products can contain hazardous substances
so correct disposal of your old appliance will help prevent
potential negative consequences for the environment and
human health. Your old appliance may contain reusable
parts that could be used to repair other products, and
other valuable materials that can be recycled to conserve
limited resources.
• You can take your appliance either to the shop where you
purchased the product, or contact your local government
waste office for details of your nearest authorised WEEE
collection point. For the most up to date information for
