USING YOUR PRODUCT
Things to Know Before Use
Install in a place where there is no electric heater or
obstacles that obstruct cooling.
• When cooling, do not use heating devices such as
irons that can hinder the cooling eectiveness. Install
in a place where there are no obstacles blocking
the air ow near the doorway, air conditioner inlet or
outlet.
When operating the air conditioner, be sure to block
direct sunlight with curtains or blinds.
• The heat coming through the windows in the summer
is 20 to 30 %, and the heat taken from the room is
10 %. Blocking direct sunlight by curtains or blinds
when using the air conditioner may lower the indoor
temperature by about 2 °C
Do not set the desired temperature of the air conditioner
too low.
• If the temperature is set lower than necessary, the
electricity consumption will increase and the air
conditioner will have to operate for a long time, which
may cause a malfunction. Excessive indoor and
outdoor temperature dierences are also harmful to
one's health and may lead to air-condition-caused
illness in the summer. At home, it is appropriate to set
the temperature at 25 to 26 °C
Use the air conditioner with an electric fan.
• Turning on an electric fan while operating the air
conditioner at weak air strength would feel almost
as cool as operating the air conditioner in strong air
strength, but with a much lower electricity bill.
Do not turn on and o the air conditioner frequently.
• For inverter products, as the temperature gets closer
to the desired temperature, the air conditioner itself
lowers the operating frequency to save power, which
may result in higher electricity bills if the product is
turned on and o frequently.
Use the air conditioner under the following operating
conditions.
• When not operating under the following temperature
conditions, the safety device may operate and the
operation may be stopped. When operating cooling
in a high humidity environment, water droplets may
appear on the air conditioner.

If the temperature rises in the place where the outdoor
unit is installed, no cold air may come out and "Od" may
appear on the indoor unit display. When "Od" appears
on the display, take the following measures.
• Open the gallery or insect screen of the outdoor unit
room.
–Using the product without opening the gallery or
insect screen in the outdoor unit room could cause
the product to run or stop repeatedly, or cool air
may not come out due to the rise in temperature.
Operate the lever (handle) as shown below.

When not using the product for a long time, unplug the
power plug or turn o the main power switch.
• When not using the product for a long time, unplug
the power plug or turn o the air conditioner breaker.
This will save electricity, and since electricity is always
owing to plugged in outdoor units, if you block it, you
can be safe from natural disasters such as lightning
and heavy rainfall.
Clean the lter thoroughly.
• If the lter gets dirty, it could result in degradation of
cooling capacity and high electricity bills. If you clean
your home air conditioner lter once every 2 weeks,
you can save 3 to 5 % in power eciency. You should
clean it more than once a month in places where
smoking is frequent, and once every 3 months in other
places.
• Remove the obstacles around the outdoor unit.
–If there are obstacles around the outdoor unit, it
could result in a degradation of cooling capacity
and higher electricity bills.
• Turning the product o and on after opening the vent
will make "Od" disappear.
