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.

of heat in the room?
●Is the set temperature suitable?
CONDITION CHECK THE FOLLOWING POINTS
Notes
●In quiet or stop operation, the following phenomena may occassionally
occur, but they are not abnormal for the operation.
(1)
Slight flowing noise of refrigerant in the refrigerating cycle.
(2) Slight rubbing noise from the fan casing which is cooled and then
gradually warmed as operation stops.
●The odor will possibly be emitted from the room air conditioner because
the various odor, emitted by smoke, foodstuffs, cosmetics and so on,
sticks to it. So the air filter and the evaporator regularly must be cleaned
to reduce the odor.
●Please contact your sales agent immediately if the air conditioner still fails to operate normally after the above
inspections. Inform your agent of the model of your unit, production number, date of installation. Please also
