removing any moisture and dust.
• Never unplug the appliance from the power supply by pulling on the
power cable. Always grip the power plug firmly and pull straight out
from the outlet socket.
• Keep ventilation openings, in the appliance enclosure or in the built-
in structure, clear of obstruction.
• Do not store explosive substances such as aerosol cans with a
flammable propellant in this appliance.

SAFETY INSTRUCTIONS
Risk of Fire and Flammable Materials
• 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.
• 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.
Installation
• This appliance should only be transported by two or more people
holding the appliance securely.
• Install the appliance on a firm and level floor.
• Do not install the appliance in a damp and dusty place. Do not install
or store the appliance in any outdoor area, or any area that is subject
to weathering conditions such as direct sunlight, wind, rain, or
temperatures below freezing.
• Do not place the appliance in direct sunlight or expose it to the heat
from heating appliances such as stoves or heaters.
• Be careful not to expose the rear of the appliance when installing.
• Install the appliance in a place where it is easy to unplug the power
plug of the appliance.
• Be careful not to let the appliance door fall during assembly or
disassembly.
• Be careful not to pinch, crush, or damage the power cable during
assembly or disassembly of the appliance door.
• Be careful not to point the power plug up or let the appliance lean
against the power plug.
• Do not modify or extend the power cable.

7
SAFETY INSTRUCTIONS
ENGLISH
• Ensure that the outlet socket 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 outlet socket that is installed
and grounded in accordance with all local codes and ordinances.
• Never start up an appliance showing any signs of damage. If in doubt,
consult your dealer.
• Dispose of all packaging materials (such as plastic bags and
styrofoam) away from children. The packaging materials can cause
suffocation.
• Do not plug the appliance into a multi socket adapter which does not
have a power cable (mounted).
• 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). It must comply with the technical specifications of the
appliance and may only be used for the appliance.
Operation
• Do not use the appliance for any purpose (storage of medical or
experimental materials or shipping) other than any domestic
household food storage use.
• If water penetrates electrical parts of the appliance, disconnect
power plug and contact an LG Electronics customer information
centre.
• Unplug the power plug during a severe thunderstorm or lightening
or when not in use for a long period of time.
• Do not touch the power plug or the appliance controls with wet
hands.

combustible substances, flammable objects (such as candles, lamps,
etc.), or heating devices (such as stoves, heaters, etc.) on the
appliance.
• Do not place any electronic appliance (such as heater and mobile
phone) inside the appliance.
• 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 refrigerant gas (isobutane,
R600a). Although it uses a small amount of the gas, it is still
combustible gas. Gas leakage during appliance transport, installation

INSTALLATION
INSTALLATION
Before Installation
Dimensions and Clearances
• Check the dimensions of the appliance and the installation path to ensure there is sufficient room to
move the refrigerator through doors or narrow openings.
• If an opening is too narrow to fit the refrigerator through, remove the refrigerator doors. See Removing/
Assembling Doors and Crispers in this manual.
• The installation location chosen for the refrigerator should allow space behind the unit for connections
and airflow and space in front to open the doors and drawers.
• Too small of a distance from adjacent items may result in lowered freezing capability and increased
electricity consumption charges. Allow at least 2 inches (50 mm) between the back of the refrigerator
and the wall.
• Remember to allow enough room in front of the refrigerator to fully open the doors.
