SAFETY PRECAUTION

!

●

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.

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 fi re may occur if you reconstruct the unit by yourself.

●

Please ask your sales agent or qualifi ed technician for the installation of your unit. Water

WARNING

!

CAUTION

leakage, short circuit or fi re may occur if you install the unit 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.

●

Be sure to use the specifi ed piping set for R410A. Otherwise, this may result in broken

copper pipes or faults.

●

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 the unit near a location where there is fl ammable gas. The outdoor unit may

catch fi re if fl ammable gas leaks around it.

●

Please ensure smooth fl ow of water when installing the drain hose.

●

Do not install the indoor unit in a machine shop or kitchen where vapor from oil or its mist
fl ows to the indoor unit. The oil will deposit on the heat exchanger, thereby reducing the
indoor unit performance and may deform and in the worst case, breake the plastic parts of
the indoor unit.

!

!

The sign in the fi gure indicates prohibition.

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 fi re may occur if you continue to operate the unit under

●

Do not insert a fi nger, a rod or other objects into the air outlet or inlet. As the fan is rotating

at a high speed, it will cause injury. Before cleaning, be sure to stop the operation and turn
the breaker OFF.

PRECAUTIONS DURING OPERATION

● The product shall be operated under the manufacturer specifi cation and

not for any other intended use.

● Do not attempt to operate the unit with wet hands, this could cause fatal

accident.

● 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, fi rm 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 fi n and blocked the evaporation water
fl ow to drain pan. The water will drop on tangential fan and cause water

splashing out from indoor unit.

!

● Please switch off the unit and turn off the circuit breaker during cleaning,

C

the high-speed fan inside the unit may cause danger.

● Do not climb on the outdoor unit or put objects on it.

● Turn off the circuit breaker if the unit is not to be operated for a long period.

ENGLISH

● 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 fl ow 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 defl ector facing down or moving automatically for a long period of time,
water will condense on the air defl ector 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 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 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.

According to “Dehumidifying” or “Cooling” operation, the
horizontal air defl ector is automatically set to the proper
angle suitable for each operation. The defl ector can be
swing up and down and also set to the desired angle
using the “ (AUTO SWING)” button. (If the angle
of the defl ector is changed, it will not return to the auto-
set position after operations start unless the operation
mode is switched.)

● If the “ (AUTO SWING)” button is pressed once,

the horizontal air defl ector swings up and down. If the
button is pressed again, the defl ector stops in its current
position. Several seconds (about 6 seconds) may be
required before the defl ector starts to move.

● In “Cooling” operation, do not keep the horizontal air

defl ector swinging for a long time. Some dew may form

on the horizontal air defl ector and dew may drop.

Adjustment of the conditioned air in the left and right directions.

● If the “ (PARALLEL SWING)” button is pressed

once, the vertical air defl ectors swing left and right to
parallel. If the button is pressed again, the defl ectors
stop in their current position. Several second (about 6
seconds) may be required before the defl ectors start to
move.
