• 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 equipment, 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.
• 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.
• 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 water container (like vase) on the indoor unit to avoid water dripping onto
the unit. Dripping water will damage the insulator inside the unit and causes short-
circuit.
• Do not place plants directly under the air flow as it is bad for the plants.
• 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.
