Electrical Safety
Electrical Safety
• This appliance must be properly grounded.
To minimize the risk of electric shock, you must always plug into a grounded oulet.
• Do not cut or remove the grounding prong from the power plug.
• Attaching the adapter ground terminal to the wall receptacle cover screw does not ground the appliance
unless the cover screw is metal and not insulated, and the wall receptacle is grounded through the
house wiring.
• If you have any doubt whether the air conditioner is properly grounded, have the wall receptacle and
circuit checked by a qualified electrician.
We strongly discourage the use of an adapter due to potential safety hazards. For temporary connections,
use only a genuine adapter, available from most local hardware stores. Ensure that the large slot in the
adapter is aligned with the large slot in the receptacle for a proper polarity connection.
To disconnect the power cord from the adapter, use one hand on each to avoid damaging the ground
terminal. Avoid frequently unplugging the power cord as this can lead to eventual ground terminal damage.
• Never use the appliance with a broken adapter.
We strongly discourage the use of an extension cord due to potential safety hazards.
Temporary Use of an Adapter

temperature range etc.(The object very different from the surrounding temperature can be mistakenly
detected.)
•
Heat emitting objects such as TV, monitor can be mistakenly detected as people. Pets, fluttering curtains,
sunlight, reflected light etc are also mistakenly detected.
•
Energy Saving mode can be occurred because of sensing uncorrectly depending on the thickness of clothes.
• It goes into Energy Saving mode if there are no people in the detecting area for 20 minutes.
• Energy Saving mode set setting temperature maximum +2°C during cooling, and maximum -2°C
during heating.
• When surrounding temperature is high(approximately over 28°C), Eco Eye Operation and Eco Eye
Energy Saving Mode is not activated.
• While Energy Saving Cooling mode operate, Eco Eye Energy Saving mode isn't activated.

This unit has an inbuilt error diagnosis capability. Unit LED will blink in case if thermistor fails.
Please contact your serviceman/dealer in such a situation
Do not overcool the room.
This is not good for the health and
wastes electricity.
Keep blinds or curtains
closed.
Do not let direct sunshine enter
the room when the air conditioner
is in operation.
Keep the room temperature
uniform.
Adjust the vertical and horizontal
airflow direction to ensure a
uniform temperature in the room.
Make sure that the
doors and windows
are shut thight.
Avoid opening doors and
windows as much as
possible to keep the cool
air in the room.
Clean the air filter
regularly.
Blockages in the air filter
reduce the airflow and
lower cooling and
dehumidifying effects.
Clean at least once every
two weeks.
Ventilate the room
occasionally.
Since windows are kept
closed, it is a good idea
to open them and
ventilate the room now
and ten.
Use high fan speed
for effective and fast
cooling.
The unit gives its rated
