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:
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.
Installation
•Do
• not install the air conditioner on an unstable surface or in a
place where there is danger of it falling.
•Contact
•
an authorized service center when installing or relocating
the air conditioner.
•Install
•
the panel and the cover of the control box safely.
4
EN
•Do
• not install the air conditioner in a place where flammable
liquids or gases such as gasoline, propane, paint thinner, etc., are
stored.
•Make
•
sure that the pipe and the power cable connecting the
indoor and outdoor units are not pulled too tight when installing
the air conditioner.
•Use
•
standard circuit breaker and fuse that conform to the rating of
the air conditioner.
•Do
• not input air or gas into the system except with the specific
refrigerant.
•Use
•
non-flammable gas (nitrogen) to check for leak and to purge
air; using compressed air or flammable gas may cause fire or
explosion.
•The
•
indoor/outdoor wiring connections must be secured tightly,
and the cable should be routed properly so that there is no force
pulling the cable from the connection terminals. Improper or loose
connections can cause heat generation or fire.
•Install
•
dedicated electric outlet and circuit breaker before using the
air conditioner.
•Do
• not connect the ground wire to a gas pipe, a lightning rod, or a
telephone ground wire.
•Keep
•
any required ventilation openings clear of obstruction.
Operation
•Be
• sure to use only those parts listed in the service parts list.
Never attempt to modify the equipment.
•Make
•
sure that children do not climb on or hit the outdoor unit.
•Dispose
•
of the batteries in a place where there is no danger of
fire.
•Use
•
only the refrigerant specified on the air conditioner label.
5
EN
•Cut
•
off the power supply if there is any noise, smell, or smoke
coming from the air conditioner.
•Do

thinner near the air conditioner.
•Contact
•
an authorized service center when the air conditioner is
submerged by flood waters.
•Do
• not use the air conditioner for an extended period of time in a
small place without proper ventilation.
•In
• the event of a gas leak (such as Freon, propane gas, LP gas,
etc.) ventilate sufficiently before using the air conditioner again.
•To
• clean the interior, contact an authorized service center or
dealer. Using harsh detergents may cause corrosion or damage to
the unit.
•Be
• sure to ventilate sufficiently when the air conditioner and a
heating appliance such as a heater are used simultaneously.
•Do
• not block the inlet or outlet of air flow.
•Do
• not insert hands or other objects through the air inlet or outlet
while the air conditioner is operating.
•Make
•
sure that the power cable is neither dirty, loose, nor broken.
•Never
•
touch, operate, or repair the air conditioner with wet hands.
•Do
• not place any objects on the power cable.
•Do
• not place a heater or other heating appliances near the power
cable.
•Do
• not modify or extend the power cable. Scratches or peeling
insulation on the power cables may result in fire or electric shock,
and should be replaced.
•Cut
•
off the power supply immediately in the event of a blackout or
a thunderstorm.
6
EN
•Take
•
care to ensure that power cable could not be pulled out or
damaged during operation.

••Dust concentration may be different according
to the installation environment. It is influenced
by couches, beds, carpets, cleaners, humidity,

••In the environment with external air inflow
such as near the door, window, or ventilation
gate, etc., dust concentration may be
measured as high.
••Even in the same space, due to the air
circulation, dust concentration may be
displayed differently from other products.

••The displayed fine dust, ultra fine dust, and

of 1.0μg/m3 or less (Cigarette smoke, etc.)
••Dust concentration and overall cleanliness
level displayed on the product may be
different from Ministry of Environment

••Ministry of Environment uses weight method
or beta ray absorption method to measure the
dust concentration, but LG product measures
the number of dusts and converts to mass
concentration, so it may be different from the
actual dust concentration.
••The same standard as ultra fine dust is
applied to super ultra fine dust’s dust
