SAFETY PRECAUTIONS
Symbols in this Use and Care Manual are interpreted as shown below.
Be sure not to do.
Pay attention to such a situation.
Grounding is essential.
Warning: Incorrect handling could
cause a serious hazard, such as death,
serious injury, etc.
Do not use the power supply circuit
breaker or pull off the plug to turn it off
during operation. This may cause a fire
due to spark, etc.
Keep the power supply circuit breaker
or plug from dirt. Connect the power
supply cord to it firmly and correctly,
lest an electric shock or a fire break out
due to insufficient contact.
Use correct power supply in
accordance with the rating plate
requirement. Otherwise, serious
faults or hazard may occur or a
fire maybe break out.
Do not knit, pull or press the power supply
cord, lest the power supply cord be broken.
An electric shock or fire is probably caused
by a broken power supply cord.
Never insert a stick or similar obstacle
to the unit. Since the fan rotates at high
speed, this may cause an injury.
Do not repair the appliance by yourself.
If this is done incorrectly, it may cause an
electric shock, etc.
Turn off the appliance by remote control
firstly before cutting off power supply if
malfunction occurs.
It is harmful to your health if the cool air
reaches you for a long time. It is advisable
to let the air flow be deflected to all the room.
Prevent the air flow from reaching the gas
burners and stove.
Do not touch the operation buttons
when your hands are wet.
Do not put any objects on the outdoor
unit.
It is the user's responsibility to make the
appliance be grounded according to
local codes or ordinances by a licenced
technician.

PROTECTION
Operating condition
Noise pollution
Install the air conditioner at a place that can bear its weight in order to operate more quietly.
Install the outdoor unit at a place where the air discharged and the operation noise would not annoy
your neighbors.
Do not place any obstacles in front of the air outlet of the outdoor unit lest it increases the noise level.
Features of protector
If all operation has stopped, press ON/OFF button again to restart, Timer should be set again if it has
been canceled.
The protective device will work at following cases.
Restarting the unit at once after operation stops or changing mode during operation, you need to wait for
3 minutes.
Connect to power supply and turn on the unit at once, it may start 20 seconds later.
Features of HEATING mode
Preheat
Defrost
At the beginning of the HEATING operation, the airflow from the indoor unit is discharged 2-5 minutes later.
In HEATING operation the appliance will defrost (de-ice) automatically to raise efficiency.
This procedure usually lasts 2-10 minutes. During defrosting, fans stop operation.
After defrosting completes, it returns to HEATING mode automatically.
Note: Heating is NOT available for cooling only air conditioner models.
