System
● Priority-room setting
When setting the priority-room during
installation, the indoor unit’s operation
mode always takes priority.
When the priority-setting room unit is
operated in POWERFUL mode, there
are times that air conditioners in other
rooms will temporarily stop in order to
centralize power to the unit in the room.
Please adjust the priority-room setting
to match your life style. Moreover, for
priority-room settings, please consult
the service shop where you bought the
unit.
∗ Priority-room setting is applied to only,

Trouble Shooting
●●
● These cases are not troubles.
●●
The following cases are not air conditioner troubles but have some reasons. You may just continue
using it.
Case
Operation does not start soon.
● When ON/OFF button was
pressed soon after operation
was stopped.
● When the mode was reselected.
The outdoor unit emits water or
steam.
Mists come out of the indoor unit.
The indoor unit gives out odour.
The outdoor fan rotates while the
air conditioner is not in operation.
Explanation
● This is to protect the air conditioner.
You should wait for about 3 minutes.
● 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
air flow during cooling operation.
■ This happens when smells of the room, furniture, or cigarettes are
absorbed into the unit and discharged with the air flow.
(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 out door fan starts
rotating for system protection.
The operation stopped suddenly.
(OPERATION lamp is on)
18
■ For system protection, the air conditioner may stop operating on a
sudden large voltage fluctuation.
It automatically resumes operation in about 3 minutes.

We recommend periodical maintenance
In certain operating conditions, the inside of the air conditioner may get foul

to have periodical maintenance by a specialist aside from regular cleaning by
the user. For specialist maintenance, contact the service shop where you
bought the air conditioner.
The maintenance cost must be born by the user.
