!

● 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.

● During thunder storm, disconnect and turn off the circuit breaker.

● Do not use any conductor as fuse wire, this could cause fatal accident.

!

Make sure to connect earth line.

Indicates the instructions that must be followed.

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 abnormal situation.

● Please contact your agent for maintenance. Improper self maintenance may cause

electric shock and ﬁ re.

● Please contact your agent if you need to remove and reinstall the unit. Electric

shock or ﬁ re may occur if you remove and reinstall the unit yourself improperly.

● If the supply cord is damaged, it must be replaced by the special cord obtainable at

authorized service/parts centers.

WARNING

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 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 near 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.

CAUTION

!

●

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.

PRECAUTIONS DURING OPERATION

 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 insufﬁ ciency.

 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.

 Do not place plants directly under the air ﬂ ow as it is bad for the plants.

 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.

 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 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.

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

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

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

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

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

not for any other intended use.

 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 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.
