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.
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 5 to 10 min-
utes.
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 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 fl owing inside the unit.
Mist seen at indoor air outlet
• In cooling operation, this is caused by the
difference between the room air temperature
and the air discharged.
Water vapour
• In heating operation, water vapour may fl ow
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 plasma-
cluster 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.
