• Do not connect the power cable with an extension cable or do not plug too many
leads of the other electric appliance into the socket where this cable is plugged.
In addition, wire the cable with some allowances to prevent the cable from stretching.
Not doing so will cause an electrical shock, heat generation or fire.
• Do not bundle the power cable, pull it, put something on it, heat it, process it, or
put it between things. Breakage of the power cable may result.
Use of a damaged cable may cause an electrical shock or a fire.
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

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.
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.•
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.

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 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.
