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 may catch fire if flammable gas leaks around it.

●Please ensure smooth flow of water when installing the drain hose.

CAUTION

PRECAUTIONS DURING SHIFTING OR MAINTENANCE

PRECAUTIONS DURING OPERATION

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

●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.

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

electric shock and fire.

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 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.

●Do not place plants directly under the air flow as it is bad for the plants.

●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.

●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.

●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 specification 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 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.
