• 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 tem-
perature 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.
Water vapour
• In heating operation, water vapour may flow
out of the outdoor unit during defrosting.
Odor emitted from the air outlet
• This is the smell of ozone generated from the
Plasmacluster Ion generator. The ozone con-
centration is very small, posing no adverse
effect on your health. The ozone discharged
into the air rapidly decomposes, and its den-
sity in the room will not increase.
