●Please read the “Safety Precaution” carefully before operating the unit to ensure correct usage of the unit.

●Pay special attention to signs of “ ! Warning” and “ ! Caution”. The “Warning” section contains matters which, if not observed strictly, may cause death or serious injury. The “Caution” section contains matters which may result in serious consequences if not observed properly. Please observe all instructions strictly to ensure safety.

●The sign indicate the following meanings.

Make sure to connect earth line.	The sign in the figure indicates prohibition.

Indicates the instructions that must be followed.

● Please keep this manual after reading.

						PRECAUTIONS DURING INSTALLATION
						● Do not reconstruct the unit.
						Water leakage, fault, short circuit or fire may occur if you reconstruct the
						unit by yourself.
	!					● Please ask your sales agent or qualified technician for the installation of
						your unit. Water leakage, short circuit or fire may occur if you install the unit
WARNING						by yourself.
						● Please use earth line.
						Do not place the earth line near water or gas pipes, lightning-conductor, or
						the earth line of telephone. Improper installation of earth line may cause
						electric shock.
						● A circuit breaker should be installed depending on the mounting site of the
	!					unit. Without a circuit breaker, the danger of electric shock exists.
						● Do not install near location where there is flammable gas. The outdoor unit
CAUTION
						may catch fire if flammable gas leaks around it.
						● Please ensure smooth flow of water when installing the drain hose.
					PRECAUTIONS DURING SHIFTING OR MAINTENANCE
!			● Should abnormal situation arises (like burning smell), please stop operating the unit
				and turn off the circuit breaker. Contact your agent. Fault, short circuit or fire may
				occur if you continue to operate the unit under abnormal situation.
W
				Please contact your agent for maintenance. Improper self maintenance may cause
A			●
R				electric shock and fire.
N			●	Please contact your agent if you need to remove and reinstall the unit. Electric
I
				shock or fire may occur if you remove and reinstall the unit yourself improperly.
N
G			● If the supply cord is damaged, it must be replaced by the special cord obtainable
				at authorized service/parts centers.
						PRECAUTIONS DURING OPERATION

● Avoid an extended period of direct air flow for your health.

!		Do not insert a finger, a rod or other objects into the air outlet or inlet. As the
W	●
A		fan is rotating at a high speed, it will cause injury. Before cleaning, be sure
		to stop the operation and turn the breaker OFF.
R
N
● Do not use any conductor as fuse wire, this could cause fatal accident.
I
N
G	● During thunder storm, disconnect and turn off the circuit breaker.

PRECAUTIONS DURING OPERATION

	● The product shall be operated under the manufacturer specification and
	not for any other intended use.
	● Do not attempt to operate the unit with wet hands, this could cause fatal
	accident.
	● When operating the unit with burning equipments, regularly ventilate the
	room to avoid oxygen insufficiency.
	● Do not direct the cool air coming out from the air-conditioner panel to face
	household heating apparatus as this may affect the working of apparatus
	such as the electric kettle, oven etc.
	● Please ensure that outdoor mounting frame is always stable, firm and
	without defect. If not, the outdoor unit may collapse and cause danger.
	● Do not splash or direct water to the body of the unit when cleaning it as this
	may cause short circuit.
	● Do not use any aerosol or hair sprays near the indoor unit. This chemical
	can adhere on heat exchanger fin and blocked the evaporation water flow
!	to drain pan. The water will drop on tangential fan and cause water splashing
	out from indoor unit.
C
A	● Please switch off the unit and turn off the circuit breaker during cleaning, the
U	high-speed fan inside the unit may cause danger.
T
I
O	● Turn off the circuit breaker if the unit is not to be operated for a long period.
N
	● Do not climb on the outdoor unit or put objects on it.
	● Do not put water container (like vase) on the indoor unit to avoid water
	dripping into the unit. Dripping water will damage the insulator inside the unit
	and causes short-circuit.
	● Do not place plants directly under the air flow as it is bad for the plants.
	● When operating the unit with the door and windows opened, (the room humidity is always above
	80%) and with the air deflector facing down or moving automatically for a long period of time,
	water will condense on the air deflector and drips down occasionally. This will wet your furniture.
	Therefore, do not operate under such condition for a long time.
	● If the amount of heat in the room is above the cooling or heating capability of the unit (for
	example: more people entering the room, using heating equipments and etc.), the preset room
	temperature cannot be achieved.
	● This appliance is not intended for use by young children or infirm persons unless they have been
	adequately supervised by a responsible person to ensure that they can use the appliance safely.
	● Young children should be supervised to ensure that they do not play with the appliance.

FAN SPEED (AUTO) ..... When the AUTO fan speed mode is set in the cooling/heating operation:

		● The fan speed will automatically change according to the temperature
		of discharged air.
	For the heating operation	● When the difference of room temperature and setting temperature is
		large, fan starts to run at HI speed.
		● When the room temperature reaches setting temperature, fan speed
		changes to LOW automatically.
		● When the difference of room temperature and setting temperature is
	For the cooling operation	large, fan starts to run at HI speed.
		● After room temperature reaches the preset temperature, the cooling
		operation, which changes the fan speed and room temperature to obtain
		optimum conditions for natural healthful cooling will be performed.
