operate the unit under abnormal situation.
●
Please contact your agent for maintenance. Improper self maintenance may cause electric
shock and fire.
●
Please contact your agent if you need to remove and reinstall the unit. Electric shock or fire
may occur if you remove and reinstall the unit yourself improperly.

●
Do not insert finger(s), 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.
WARNING
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 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 may catch
fire if flammable gas leaks around it.
●
Please ensure smooth flow 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 flows 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.

PRECAUTIONS DURING OPERATION
●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.
●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 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 can be used by children aged from 8 years and above and persons with reduced
physical, sensory or mental capabilities or lack of experience and knowledge if they have been
given supervision or instruction concerning use of the appliance in a safe way and understand
the hazards involved.
Children shall not play with the appliance. Cleaning and user maintenance shall not be made
by children without supervision
●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.
