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.

AIR SLEEP MODE
The sensor detects changes to the infrared generated by human bodies. Therefore, the accuracy of sensor may be
affected in the following cases:
■The activity level is very low (reading, watching TV, etc.) or human bodies are blocked by a screen, cabinet or
glass board.
■The indoor temperature is very high and exceeds or approaches the human body temperature (when the refrigeration
just begins).
■The person wears thick clothes and turns his/her back to the air conditioner.
■Curtains or plant leaves swing due to pet movement or airflow.
With the air sleep sensor, the air conditioner can monitor the activity/movement level in a room and adjust the temperature
and humidity automatically, thus achieving the purpose of comfortable sleep environment and enegry saving.
