OPERATION INSTRUCTIONS
WARNINGS FOR USE
1Do 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.
2Be careful not to expose your body directly to the outlet air for a long time. It may affect your
physical conditions.
3When using the air conditioner for infants, children, elderly, bedridden, or disabled people
make sure the room temperature is suitable for those in the room.
4Never insert objects into the unit. Inserting objects can result in injury due to the high speed
rotation of internal fans.
5Ground 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.
6If anything is abnormal with the air conditioner (ex. a burning smell), stop the operation
immediately and turn the circuit breaker OFF.
7The 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.
8If 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.
CAUTIONS FOR USE
1Open a window or door periodically to ventilate the room, especially when using gas
appliances. Insufficient ventilation may cause oxygen shortage.
2
3For safety, turn the circuit breaker off when not using the unit for an extended period of time.
4This 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.
5Do not place a vessel with water on the unit. If water penetrates into the unit, electrical
insulations may deteriorate and cause electric shock.
6Do not block the air inlets nor outlets of the unit. It may cause insufficient performance or
troubles.
PRECAUTIONS
Do not operate the buttons with wet hand. It may cause electric shock.

WATER IN THE BOTTOM TRAY
Water will be collected at the bottom tray of the unit. This is normal condition. Water condenses
on the evaporator coil in the front part of the unit and is channeled to the rear where it is picked
up by the condenser fan. The water is blown onto the condensor coil fins, this creates a "splashing"
sound which is normal. When the tray is filled up with water, excessive water will be drained
outside through a grooved channel in the tray.
WAIT 3 MINUTES UNTIL COOLING OPERATION STARTS
When you turn the air conditioner OFF and restart it again soon, wait at least 3 minutes before
the cooling operation starts. This is because the compressor stops for 3 minutes for it's protection.
IF A POWER FAILURE OCCURS DURING OPERATION, WAIT 3 MINUTES BEFORE
RESTARTING THE OPERATION
After power is reinstated, restart the air conditioner. If the power was off less than 3 minutes, be
sure to wait at least three minutes before restarting the unit. If you restart the air conditioner within
3 minutes, a protective device in the unit may cause the air conditioner to shut off. This protective
device will prevent COOL/DRY operation for about 5 minutes.
PRECAUTIONS
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.
ADDITIONAL NOTES ON OPERATION
7Be 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.
8
Do not splash or pour water directly on the unit. Water can cause electrical shock or
equipment damage.
9
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.

AIR FLOW AND VENTILATION
Airflow direction can be adjusted by moving the
airflow adjustment louvers upward or downward.
To avoid condensation on the louvers, please do
not adjust these louvers to extremely downward
position during COOL and DRY modes.
If air in your room is stale, set the VENTILATION
lever to the RIGHT (OPEN) position. This will
remove stale air from the room. The VENTILATION
lever should normally be kept in the LEFT (CLOSED)
position during cooling operation for maximum
cooling effect.
Adjust the louvers to change the direction of air
flow. Press the SWING button on the remote
control, and the Left/Right air flow adjustment louvers
will swing continuously. Press the button again to
stop. You can adjust the air flow to your desired
direction.
Never attempt to move the Left/Right air flow
adjustment louvers manually, or manually force the
louver movement to stop during swing operation.
