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.
When using AY-XPC18LR as a multi-
system air conditioner
An indoor unit which is not in opera-
tion is getting warm.
Warm air is coming out from an indoor
unit in PLASMACLUSTER only mode.
• The refrigerant is fl owing through the indoor
unit when the other unit is operating in HEAT
mode.
No air fl ow comes out of an indoor unit
when the unit is in PLASMACLUSTER
only mode or SELF CLEAN operation.
• The outdoor unit is defrosting.
An indoor unit starts to beep, and the
OPERATION lamp and TIMER lamp

• Check if all the indoor units are set to the
same mode. If not, set all the indoor units to
