Check

If the protective device works to protect the appliance.
If circuit breaker tripped or if the fuse is blown.
If the intakes and outlets of the air conditioner are
blocked.
If the temperature is not set properly.
If the air filter is dirty.
If strong interference(from excessive static electricity
discharge, power supply voltage abnormality)is present,
operation will be abnormal. At this time, disconnect from
the power supply by turning off the circuit breaker and
connect back 2-3 seconds later.
Changing mode during operation will delay
start-up for 3 minutes.
This odor may come from another source
such as furniture, cigarette etc, which is
sucked into the unit and is blown out with the air.
Caused by the flow of refrigerant in the
air conditioner. This is not a problem.
The sound may be generated by the expansion
or contraction of the front panel due to change
of temperature.This is not a problem.
Mist appears when the room air becomes
very cold because of cool air discharged
from indoor unit during COOLING or DRY
operation mode.
If the distance is obscured between the remote
controller and the unit.
Are the batteries exhausted? Replace them with new
ones,and repeat the operation again.
