BEFORE CALLING FOR SERVICE
The following conditions do not denote
equipment malfunctions.
UNIT DOES NOT OPERATE
The unit will not operate if it is turned on im-
mediately after it is turned off. The unit will not
operate immediately after the mode is changed.
This is to protect the unit. Wait 3 minutes before
operating the unit.
ODORS
Carpet and furniture odors that entered into the
unit may be sent out from the unit.
CRACKING NOISE
This sound is generated by the friction of the
unit expanding or contracting due to a tempera-
ture change.
MIST SEEN AT INDOOR AIR OUTLET
In cooling operation, this is caused by the differ-
ence between the room air temperature and the
air discharged.
THE OUTDOOR UNIT DOES NOT STOP
After stopping the operation, the outdoor unit
will rotate its fan for about a minute to cool
down the unit.
SWISHING NOISE
The soft, swishing noise is the sound of the
refrigerant fl owing inside the unit.
(For High end models only)
A LOW BUZZING NOISE
This is a sound of the unit generating Plasma-
cluster ions.
ODOR EMITTED FROM THE PLASMA-
CLUSTER AIR OUTLET
This is the smell of ozone generated from
the Plasmacluster Ion generator. The ozone
concentration is very small, posing no adverse
effect on your health. The ozone discharged
into the air rapidly decomposes, and its density
in the room will not increase.
