A buzz sound will signal that the auto restart function is cancelled and the air conditioner is in standby.
SAFETY PRECAUTIONS
Be sure not to do the following.
It is harmful to your health if the cool air reaches you for a long time. It is
advisable to let the air flow be deflected to all the room.
Prevent the air flow from reaching the gas burners and stove.
Do not touch the operation buttons when your hands are wet.
Pay attention to such a situation.
Do not repair the appliance by yourself. If this is done incorrectly, it may
cause an electric shock, etc.
Be sure to follow this instruction.
Do not put any objects on the outdoor unit.
Earthing is essential.
It is the user’s responsibility to have the appliance be earthed according to
local laws by a qualified technician.
Warning: Incorrect handling could cause a serious hazard, such as
death, serious injury, etc.
Use correct power supply in accordance with the rating plate
requirement. Don't use any extension cord for power supply. Otherwise,
serious faults or hazard may occur or a fire may break out.
Keep the power supply circuit breaker or plug from dirt. Connect the
power supply cord to it firmly and correctly, lest an electric shock or a fire
break out due to insufficient contact.
Do not use the power supply circuit breaker or pull off the plug to turn it
off during operation. This may cause a fire due to spark, etc.
Do not twist, pull or press the power supply cord, lest the power supply
cord be broken. An electric shock or fire is probably caused by a broken
power supply cord.
Never insert a stick or similar obstacle in the unit. Since the fan rotates at
high speed, this may cause an injury.
Turn off the appliance with remote control first before cutting off power
supply if malfunction occurs.
