Operation Manual
Explanation
• This is to protect the air conditioner.
You should wait for about 3 minutes.
• The air conditioner is warming up. You should wait for 1 to 4 minutes.
(The system is designed to start discharging air only after it
has reached a certain temperature.)
• The system is taking away the frost on the outdoor unit.
You should wait for about 4 to 12 minutes.
In HEAT mode
• The frost on the outdoor unit melts into water or steam
when the air conditioner is in defrost operation.
In COOL or DRY mode
• Moisture in the air condenses into water on the cool
surface of outdoor unit piping and drips.
This happens when the air in the room is cooled into mist by
the cold airflow during cooling operation.
This is because the air in the room is cooled by the heat
exchanger and becomes mist during defrost 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 another 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 malfunc-
tioning. Replace all the batteries with new size AAA alkaline
batteries. For details, refer to "To set the batteries" of this
manual. (page 7.)
* If the reset button is provided, press the reset button after the
batteries are replaced.
• Check if the ON/OFF TIMER and the WEEKLY TIMER are
set to the same time.
Change or disable the settings in the WEEKLY TIMER.
