injury or scalding to persons when using this product,
follow basic precautions, including the following:
Children in the Household
•This appliance is not intended for use by persons (including
children) with reduced physical, sensory or mental capabilities, or
lack of experience and knowledge, unless they have been given
supervision or instruction concerning use of the appliance by a
person responsible for their safety. Children should be supervised
to ensure that they do not play with the appliance.

5
EN
•If the appliance is equipped with a lock (some countries only),
keep the key out of reach of children.
Installation
•This appliance should only be transported by two or more people
holding the appliance securely.
•Ensure that the socket outlet is properly grounded, and that the
earth pin on the power cord is not damaged or removed from the
power plug. For more details on grounding, inquire at an LG
Electronics customer information centre.
•This appliance is equipped with a power cord having an
equipment-grounding conductor and a grounding power plug. The
power plug must be plugged into an appropriate socket outlet that
is installed and grounded in accordance with all local codes and
ordinances.
•If the power cord is damaged or the hole of the socket outlet is
loose, do not use the power cord and contact an authorized
service centre.
•Do not plug the appliance into a multi socket adapter which does
not have a power cable(mounted).
•Do not modify or extend the power cable.

6
EN
•Avoid using any extension cords or double adaptor. The appliance
should be connected to a dedicated power line which is separately
fused.
•Do not use a multi socket outlet which is not properly
grounded(portable). In case of using a properly-grounded multi
socket outlet (portable), use the multi socket outlet with the current
capacity of the power code rating or higher and use the multi
socket outlet only for the appliance. Failure to do so may result in
electric shock or fire due to the heat of multi socket outlet. The
power may be shut off when the circuit breaker is operated.
•Install the appliance in a place where is easy to unplug the power
plug of the appliance.
•Be careful not to point the power plug up or let the appliance lean
against the power plug.

•If there is a gas leakage (isobutane, propane, natural gas, etc.),
do not touch the appliance or power plug and ventilate the area
immediately. This appliance uses a very eco-friendly gas
(isobutane, R600a) as the refrigerant. Although it uses a small
amount of the gas, it is still combustible gas. Gas leakage during
appliance transport, installation or operation can cause fire,
explosion or injury if sparks are caused.
•Do not use or store flammable or combustible substances (ether,
benzene, alcohol, chemical, LPG, combustible spray, insecticide,
air freshener, cosmetics, etc.) near the appliance.
•Immediately unplug the power plug and contact an LG Electronics
customer information centre if you detect a strange sound, odour,
or smoke coming from the appliance.
•Fill with potable water only into icemaker or dispenser water tank.
Maintenance
•Disconnect the power cord before cleaning the appliance or
replacing the inside lamp (where fitted).
•Securely plug the power plug in the socket outlet after completely
removing any moisture and dust.
•Never unplug the appliance by pulling on the power cable. Always
grip the power plug firmly and pull straight out from the socket
outlet.
•Do not spray water or inflammable substances(toothpaste, alcohol,
thinner, benzene, flammable liquid, abrasive, etc.) over the interior
or exterior of the appliance to clean it.
•Do not clean the appliance with brushes, cloths or sponges with
rough surfaces or which are made of metallic material.

9
EN

built-in structure, clear of obstruction.
•Do not use electrical appliances inside the food storage
compartments of the appliance, unless they are of the type
recommended by the manufacturer.
•The refrigerant and insulation blowing gas used in the appliance
require special disposal procedures. Consult with service agent or
a similarly qualified person before disposing of them.

10
EN
•Refrigerant leaking out of the pipes could ignite or cause an
explosion.
•The amount of refrigerant in your particular appliance is shown on
the identification plate inside the appliance.

(R600a), but it is also combustible. When transporting and
installing the appliance, care should be taken to ensure that no
parts of the refrigerating circuit are damaged.
•If a leak is detected, avoid any naked flames or potential sources
of ignition and air the room in which the appliance is standing for
several minutes. In order to avoid the creation of a flammable gas
air mixture if a leak in the refrigerating circuit occurs, the size of
the room in which the appliance is used should correspond to the
amount of refrigerant used. The room must be 1 m² in size for
every 8 g of R600a refrigerant inside the appliance.

INSTALLATION EN
Notes for Installation
•Install the appliance on a solid and flat area.
−If the appliance is installed on an uneven
floor, it can cause vibration and noise
causing the appliance to fall resulting in
injury. It could also cause the doors not to
close correctly and introduce moisture inside
the unit during operation.
−If the appliance front or rear is not level,
adjust the front feet so that it can be
corrected. Severe cases may need the floor
to be packed out with strips of thin timber.
•Avoid placing the unit near heat sources,
direct sunlight or moisture.
•Connect the power supply cord (or plug) to
the outlet. Don't double up with other
appliances on the same outlet.
•After connecting the power supply cord (or
plug) to the outlet, Wait two or three hours
before you put food into the appliance. If you
add food before the appliance has cooled
completely, your food may spoil.
•After installing the appliance, connect the
power plug into a socket outlet. Before moving
and discarding the appliance, disconnect the
plug from the socket outlet.
Before Installation
Notes for Movement and
Transport
•Remove all food from inside the appliance.
Then, transport the appliance only after fixing
fragile parts such as shelves and the door
handle with tape. Failure to do so may cause
appliance damage.
•Pull the power plug out, insert and fix it into
the power plug hook at the rear or on top of
the appliance. Failure to do so may cause
damage to the power plug or floor scratch.
•When transporting the appliance, more than
two people should transport the appliance
carefully. Dropping the appliance, which is
extremely heavy, may cause personal injury or
appliance failure.
•When transporting the appliance over a long
distance, keep the appliance upright. The
appliance may fall over, causing malfunctions.
Never transport the appliance laying down as
it can cause a refrigerant circulation
malfunction when it is turned back on again.
