• This is to protect the air conditioner.
You should wait for about 3 minutes.
„ In COOL or DRY mode
• Moisture in the air condenses into water on the cool
surface of outdoor unit piping and drips.
„ In HEAT operation
• The frost on the outdoor unit melts into water or steam
when the air conditioner is in defrost operation.
• This happens when the air in the room is cooled into mist by
the cold airflow during cooling operation.
• This happens when smells of the room, furniture, or
cigarettes are absorbed into the unit and discharged with the
airflow.
(If this happens, we recommend you to have the indoor unit
washed by a technician. Consult the service shop where you
bought the air conditioner.)
„ After operation is stopped:
• The outdoor fan continues rotating for about 60 seconds
for system protection.
„ While the air conditioner is not in operation:
• When the outdoor temperature is very high, the outdoor
fan starts rotating for system protection.
• For system protection, the air conditioner may stop operating
on a sudden large voltage fluctuation.
It automatically resumes operation in about 3 minutes.
• The batteries are dying and the remote controller is
malfunctioning. Replace all the batteries with new size
AAA.LR03 (alkaline) batteries. For details, refer to "To set the
batteries" of this manual.
