BEFORE CALLING FOR SERVICE
The following conditions do not denote equip-
ment 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.
Unit does not send out warm air
• In heating operation, the indoor fan may not
start for 2 to 5 minutes after the unit is turned on
to prevent cold air from blowing out of the unit.
• The unit is defrosting. Wait for 3 to 12 minutes.
During defrosting, the red TURBO FAN lamp
( ) on the unit flashes.
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 re-
frigerant flowing inside the unit.
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.
Water vapour
• In heating operation, water vapour may flow out
of the outdoor unit during defrosting.
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 con-
centration is very small, posing no adverse ef-
fect on your health. The ozone discharged into
the air rapidly decomposes, and its density in
the room will not increase.
Check the following points before calling for
service.
