IMPORTANT SAFETY INSTRUCTIONS
WARNINGS FOR USE
1
Do not pull or deform the power supply cord. Pulling and misuse of the power supply cord
can result in damage to the unit and cause electrical shock.
2
Be careful not to expose your body directly to the outlet air for a long time. It may affect
your physical conditions.
3
When using the air conditioner for infants, children, elderly, bedridden, or disabled people
make sure the room temperature is suitable for those in the room.
4
Never insert objects into the unit. Inserting objects can result in injury due to the high
speed rotation of internal fans.
5
Ground the air conditioner without fail. Do not connect the grounding wire to gas pipe,
water pipe, lightning rod or telephone grounding wire. Incomplete grounding may cause
electric shock.
6
If anything is abnormal with the air conditioner (ex. a burning smell), stop the operation
immediately and turn the circuit breaker OFF.
7
The appliance shall be installed in accordance with national wiring regulations. Improper
cable connection can cause the power supply cord, plug and the electrical outlet to
overheat and cause fire.
8
If the supply cord is damaged, it must be replaced by the manufacturer or its service agent
or a similarly qualified person in order to avoid a hazard. Use only the manufacture-
specified power cord for replacement.
WARNINGS FOR INSTALLATION / REMOVAL / REPAIR
• Do not attempt to install/remove/repair the unit by yourself. Incorrect work will cause electric
shock, water leak, fire etc. Consult your dealer or other qualified service personnel for the
installation/removal/repair of the unit.
IMPORTANT SAFETY INSTRUCTIONS
CAUTIONS FOR USE
1
Open a window or door periodically to ventilate the room, especially when using gas
appliances. Insufficient ventilation may cause oxygen shortage.
2
Do not operate the buttons with wet hand. It may cause electric shock.
3
For safety, turn the circuit breaker off when not using the unit for an extended period of
time.
4
Check the outdoor unit mounting rack periodically for wear and to make sure it is firmly
in place.
5
Do not put anything on the outdoor unit nor step on it. The object or the person may fall
down or drop, causing injury.
6
This unit is designed for residential use. Do not use for other applications such as in a
kennel or greenhouse to raise animals or grow plants.
7
Do not place a vessel with water on the unit. If water penetrates into the unit, electrical
insulations may deteriorate and cause electric shock.
8
Do not block the air inlets nor outlets of the unit. It may cause insufficient performance
or troubles.
9
Be sure to stop the operation and turn the circuit breaker off before performing any
maintenance or cleaning. A fan is rotating inside the unit and you may get injured.
10
Do not splash or pour water directly on the unit. Water can cause electrical shock or
equipment damage.
11
This appliance is not intended for use by young children or infirm persons without
supervision.
Young children should be supervised to ensure that they do not play with the appliance.
CAUTIONS FOR LOCATION / INSTALLATION
• Make sure to connect the air conditioner to power supply of the rated voltage and
frequency.
Use of a power supply with improper voltage and frequency can result in equipment
damage and possible fire.
• Do not install the unit in a place where inflammable gas may leak. It may cause fire.
Install the unit in a place with minimal dust, fumes and moisture in the air.
• Arrange the drain hose to ensure smooth drainage. Insufficient drainage may cause wetting
of the room, furniture etc.
• Make sure a leak breaker or a circuit breaker is installed, depending on the installation
location, to avoid electrical shock.

OPERATING TEMPERATURE RANGE
• The built-in protective device may prevent the unit from operating when used out of this
range.
• Condensation may form on the air outlet if the unit operates continuously in the COOL or
DRY mode when humidity is over 80 percent.
D.B. = Dry-bulb W.B. = Wet-bulb
TIPS ON SAVING ENERGY
Below are some simple ways to save energy when you use your air conditioner.
WHEN POWER FAILURE OCCURS
This air conditioner has a memory function to store settings when a power failure occurs.
After power recovery, the unit will automatically re-start in the same settings which were
active before the power failure, except for timer settings.
If the timers were set before a power failure, they will need to be re-set after power recovery.
5
SET THE CORRECT TEMPERATURE
• Setting the thermostat 1°C higher than the desired temperature in the COOL mode will
save approximately 10 percent in power consumption.
• Setting the temperature lower than necessary during cooling operation will result in
increased power consumption.
BLOCK DIRECT SUNLIGHT AND PREVENT DRAFTS
• Blocking direct sunlight during cooling operation will reduce power consumption.
• Close the windows and doors during cooling operation.
SET PROPER AIR FLOW DIRECTION TO OBTAIN THE BEST AIR
CIRCULATION
KEEP FILTER CLEAN TO ENSURE THE MOST EFFICIENT OPERATION
MAKE MOST OF THE TIMER OFF FUNCTION
DISCONNECT THE POWER CORD OR TURN OFF THE CIRCUIT BREAKER
WHEN THE UNIT IS NOT USED FOR AN EXTENDED PERIOD OF TIME
• The indoor unit still consumes a small amount of power when it is not operating.

IF THE UNIT FAILS TO RECEIVE THE REMOTE CONTROL SIGNAL
Check whether the remote
control batteries have be-
come old and weak.

BEFORE CALLING FOR SERVICE
The following conditions do not denote equipment malfunctions
UNIT DOES NOT OPERATE
The unit will not operate if it is turned on
immediately after it is turned off. The unit will not
operate immediately after the mode is changed.
This is to protect the internal mechanisms. Wait 3
minutes before operating the unit.
CRACKING NOISE
The unit may produce a cracking noise. This sound
is generated by the friction of the front panel and
other components expanding or connecting due to
a temperature change.
If the unit appears to be malfunctioning, check the following points before calling for
service.
IF THE UNIT FAILS TO OPERATE
• Check to see if the circuit breaker has tripped or the fuse has blown.
• Check if the louver unit is properly installed. All lamps on the indicator panel will blink when
the louver unit is not properly installed.
IF THE UNIT FAILS TO COOL THE ROOM EFFECTIVELY
Check the filters. If dirty,
clean them.
Check the outdoor unit to
make sure nothing is blocking
the air inlet or outlet.
Check the thermostat is
proper setting.
Make sure windows and
doors are closed tightly.
A large number of people in
the room can prevent the unit
from achieving the desired
temperature.
Check whether any heat-
generating appliances are
operating in the room.
ODORS
Carpet and furniture odors that entered into the
unit and the air conditioner's inner component
odors at the early stage of installation may be
sent out from the unit.
SWISHING NOISE
The soft, swishing noise is the sound of
the refrigerant flowing inside the unit.
WATER VAPOUR
In the COOL and DRY operation, water
vapour can sometimes be seen at the
air outlet due to the difference between
the room air temperature and the air
discharged by the unit.
Please call for service when OPERATION Lamp and TIMER Lamp on the indicator panel blink.
