Description / where to check
„ In HEATING operation
• The air conditioner is warming up. Wait for about 1 to 4 minutes.
„ In COOLING / "SARARA" DRY / DRY COOLING operation
• When the airfl ow rate setting is "AUTO", a function to prevent emission of an odour
contained in the indoor unit operates. This keeps air from coming out immediately after
operation is started. Wait for about 40 seconds.
„ Is the airfl ow rate setting appropriate?
• Is the airfl ow rate setting low, such as "Indoor unit quiet" or "1"? Increase the airfl ow rate
setting.
„ Is the set temperature appropriate?
„ Is the adjustment of the airfl ow direction appropriate?
• Is there any furniture directly under or beside the indoor unit?
• Is the air conditioner in ECONO operation?
• Are the air fi lters dirty?
• Is there anything blocking the air inlet or air outlet of the indoor unit or outdoor unit?
• Is the window or door open?
• Is the exhaust fan turning?
Description / where to check
• When operation is switched to "SARARA" DRY operation, the humidity may increase
temporarily, which may generate an odour.
• The room odour absorbed in the unit is discharged with the airfl ow.
We recommend you to have the indoor unit cleaned. Consult the service shop.
• The air outlet may give out an odour because a small amount of ozone is generated.
However, the amount is very small and does not harm your health.
• This happens when the unit is in MOLD PROOF operation.
Description / where to check
• This happens when the air in the room is cooled into mist by the cold airfl ow during
COOLING or other operation.
• This is because the air in the room is cooled by the heat exchanger and becomes mist
during defrost operation.
Description / where to check
• The batteries may be exhausted.
Replace all the batteries with new dry batteries AA.LR6 (alkaline).
For details, refer to "Preparation before operation".
• If the remote controller activates other electric devices, move them away or consult the
service shop.
• If you do not want to operate 2 air conditioners at the same time, change the address
setting.
