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 min-
utes 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 connecting due to a tempera-
ture change.
A LOW BUZZING NOISE
This is a sound of the unit generating Plasma-
cluster ions.
SWISHING NOISE
The soft, swishing noise is the sound of the
refrigerant flowing inside the unit.
MIST SEEN AT INDOOR AIR OUTLET
In cooling operation, this is caused by the dif-
ference 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.
ODOR EMITTED FROM THE
PLASMACLUSTER 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.
