- Air conditioners should not be installed in
areas where corrosive gases, such as acid
or alkaline gas, are produced.
- Do not install the product where it could be
exposed to sea wind (salty wind) directly. It
can result corrosion on the product.
Corrosion, particularly on the condenser
and evaporator fins, could cause product
malfunction or inefficient performance.
- If outdoor unit is installed close to the sea-
side, it should avoid direct exposure to the
sea wind. Otherwise it needs additional
anticorrosion treatment on the heat
exchanger.
Installation guide at the
seaside
Selecting the location
(Outdoor Unit)
If the outdoor unit is to be installed close to
the seaside, then direct exposure to the sea
wind should be avoided.
Install the outdoor unit on the opposite side of
the sea wind direction.
In case of installing the outdoor unit on the
sea side, setup a windbreak to prevent sea
wind.
- It should be strong enough like concrete to
prevent the sea wind from the sea.
- The height and width should be more than
150% of the outdoor unit.
- Keep more than 70 cm of space between
outdoor unit and the windbreak for easy air
flow.
Select a well-drained place.

- If you can’t meet above guide line in the
seaside installation, please contact LG
Electronics for the additional
anticorrosion treatment.
- Periodic ( more than once/year ) cleaning
of the dust or salt particles stuck on the
heat exchanger by using water
* Do not use seawater when you clean up
the heat exchanger.

Precautions about installation in regions with extreme snowfall and cold temper-
atures
To ensure the outdoor unit operates properly, certain measures are required in locations where there
is a possibility of heavy snowfall or severe wind chill or cold :
1
Prepare for severe winter wind chills and heavy snowfall, even in areas of the country where these
are unusual phenomena.
2
Position the outdoor unit so that its airflow fans are not buried by direct, heavy snowfall.
If snow piles up and blocks the airflow, the system may malfunction.
3
Remove any snow that has accumulated 100 mm or more on the top of the outdoor unit.
4
Place the outdoor unit on a raised platform at least 500 mm higher than the aver- age annual snow-
fall for the area. If the frame width is wider than the outdoor unit, snow may accumulate.
5
Install a snow protection hood.
6
To prevent snow and heavy rain from entering the outdoor unit, install the suction and dis- charge
ducts facing away from direct winds.
7
Additionally, the following conditions should be taken into consideration when the unit operates in
defrost mode:
- If the outdoor unit is installed in a highly humid environment (near an ocean, lake, etc.), en- sure
that the site is well-ventilated and has a lot of natural light. (Example: Install on a rooftop.)
TIPS FOR SAVING ENERGY
Here are some tips that will help you minimize the power consumption when you use the air
conditioner. You can use your air conditioner more efficiently by referring to the instructions
below:
• Do not cool excessively indoors. This may be harmful for your health and may consume more electricity.
• Block sunlight with blinds or curtains while you are operating the air conditioner.
• Keep doors or windows closed tightly while you are operating the air conditioner.
• Adjust the direction of the air flow vertically or horizontally to circulate indoor air.
• Speed up the fan to cool or warm indoor air quickly, in a short period of time.
• Open windows regularly for ventilation as the indoor air quality may deteriorate if the air conditioner is used
for many hours.
• Clean the air filter once every 2 weeks. Dust and impurities collected in the air filter may block the air flow or
weaken the cooling / dehumidifying functions.
