INSTALLATION WARNINGS
•
Ask an authorized dealer to install this air conditioner. Inappropriate installation may cause water
leakage, electric shock, or re.
•
All repairs, maintenance and relocation of this unit must be performed by an authorized service
technician. Inappropriate repairs can lead to serious injury or product failure.
WARNINGS FOR PRODUCT USE
•
If an abnormal situation arises (like a burning smell), immediately turn off the unit and pull the
power plug. Call your dealer for instructions to avoid electric shock, re or injury.
•
Do not
insert ngers, rods or other objects into the air inlet or outlet. This may cause injury, since
the fan may be rotating at high speeds.
•
Do not
use ammable sprays such as hair spray, lacquer or paint near the unit. This may cause
re or combustion.
•
Do not
operate the air conditioner in places near or around combustible gases. Emitted gas may
collect around the unit and cause explosion.

ELECTRICAL WARNINGS
• Only use the specied power cord. If the power cord is damaged, it must be replaced by the
manufacturer or certied service agent.
• Keep power plug clean. Remove any dust or grime that accumulates on or around the plug. Dirty
plugs can cause re or electric shock.
• Do not pull power cord to unplug unit. Hold the plug rmly and pull it from the outlet. Pulling
directly on the cord can damage it, which can lead to re or electric shock.
• Do not use an extension cord, manually extend the power cord, or connect other appliances to
the same outlet as the air conditioner. Poor electrical connections, poor insulation, and insufcient
voltage can cause re.
CLEANING AND MAINTENANCE WARNINGS
• Turn off the device and pull the plug before cleaning. Failure to do so can cause electrical shock.
• Do not clean the air conditioner with excessive amounts of water.
• Do not clean the air conditioner with combustible cleaning agents. Combustible cleaning agents
can cause re or deformation.
CAUTION
• If the air conditioner is used together with burners or other heating devices, thoroughly ventilate
the room to avoid oxygen deciency.
• Turn off the air conditioner and unplug the unit if you are not going to use it for a long time.
• Turn off and unplug the unit during storms.
• Make sure that water condensation can drain unhindered from the unit.
• Do not operate the air conditioner with wet hands. This may cause electric shock.
• Do not use device for any other purpose than its intended use.
• Do not climb onto or place objects on top of the outdoor unit.
• Do not allow the air conditioner to operate for long periods of time with doors or windows open,
or if the humidity is very high.

Achieving Optimal Performance
Optimal performance for the COOL, HEAT, and DRY modes can be achieved in the following
temperature ranges. When your air conditioner is used outside of these ranges, certain safety
protection features will activate and cause the unit to perform less than optimally.

Other Features
• Auto-Restart
If the unit loses power, it will automatically
restart with the prior settings once power has
been restored.
• Anti-mildew (not available)
When turning off the unit from COOL, AUTO
(COOL), or DRY modes, the air conditioner will
continue operate at very low power to dry up
condensed water and prevent mildew growth.
• Wireless Control
Wireless control allows you to control
your air conditioner using your mobile
phone and a Wireless connection.
• Louver Angle Memory
When turning on your unit, the louver
will automatically resume its former
angle.
• Refrigerant Leakage Detection
The indoor unit will automatically
display “EC” when the unit detects
refrigerant leakage.
NOTE ON ILLUSTRATIONS
Illustrations in this manual are for explanatory purposes. The actual shape of your indoor
unit may be slightly different. The actual shape shall prevail.
For a detailed explanation of your unit’s
advanced functionality (such as TURBO
mode and its self-cleaning functions),
refer to the Remote Control Manual.
For the USB device access, replacement,
maintenance operations must be carried
out by professional staff.

The horizontal angle of the airow must be set
manually. Grip the deector rod (See Fig.B)
and manually adjust it to your preferred direction.
For some units, the horizontal angle of the airow
can be set by remote control. please refer to the
Remote Control Manual.
NOTE ON LOUVER ANGLES
When using COOL or DRY mode, do not set
louver at too vertical an angle for long periods
of time. This can cause water to condense on
the louver blade, which will drop on your oor
or furnishings. (See Fig.A)
When using COOL or HEAT mode, setting the
louver at too vertical an angle can reduce the
performance of the unit due to restricted air
ow.
Do not move louver by hand. This will cause the
louver to become out of sync. If this occurs, turn
off the unit and unplug it for a few seconds,
then restart the unit. This will reset the louver.

CAUTION
Do not put your ngers in or near the blower
and suction side of the unit. The high-speed

go to sleep. When in COOL mode, the unit will
increase the temperature by 1°C (2°F) after 1
hour, and will increase an additional 1°C (2°F)
after another hour. When in HEAT mode, the unit
will decrease the temperature by 1°C (2°F) after
1 hour, and will decrease an additional 1°C (2°F)
after another hour.
It will hold the new temperature for 5 hours, then
the unit will turn off automatically.
