When the Need Arises
English
Mist comes out
Case Description / what to check
Mist comes out of the indoor unit.
• This happens when the air in the room is cooled into mist by the cold airflow during COOL
or other operation.
Remote controller
Case Description / what to check
The unit does not receive signals
from the remote controller or has
a limited operating range.
• The batteries may be exhausted. Replace both batteries with new dry batteries AAA.LR03
(alkaline). For details, refer to “
Preparation Before Operation
”. Page 10
• Signal communication may be disabled if an electronic-starter-type fluorescent lamp
(such as inverter-type lamps) is in the room. Consult your dealer if that is the case.
• The remote controller may not function correctly if the transmitter is exposed to direct
sunlight.
LCD is faint, is not working, or the
display is erratic.
• The batteries may be exhausted. Replace both batteries with new dry batteries AAA.LR03
(alkaline). For details, refer to “
Preparation Before Operation ”. Page 10
The LCD is blinking and the remote
controller cannot be operated.
• Battery power has run out.
Replace both batteries at the same time with new size AAA.LR03 (alkaline) batteries.
Leaving exhausted batteries in the remote controller can result in injury due to battery
leakage, rupturing or heating, or lead to equipment failure.
(Even when the LCD is blinking, the OFF button remains functional.)
Other electric devices start operating.
• If the remote controller activates other electric devices, move them away or consult your dealer.
Air has an odour
Case Description / what to check
The air conditioner gives off an
odour.
• The room odour absorbed in the unit is discharged with the airflow.
We recommend that you have the indoor unit cleaned. Please consult your dealer.
• Due to streamer discharge, the air outlet may emit a slight odour as trace amounts of ozone
are generated. However, the amount is negligible and is not harmful to your health.
Display lamps
Case Description / what to check
The OPERATION lamp is off, but
the air conditioner is operating.
• Is the display brightness set to “Off”?
• MOLD PROOF operation is being performed.
It is possible to stop MOLD PROOF operation while it is in progress.
(If this does not suit your preferences, set MOLD PROOF to “Off”.)
The display lamps on the main
unit are dark.
• Is the display brightness set to “Low”?
Streamer air cleaning operation
Case Description / what to check
The sound of streamer discharge
can no longer be heard.
• If the airflow becomes weak, the streamer discharge stops.
Others
Case Description / what to check
The air conditioner suddenly starts
behaving strangely during operation.
• The air conditioner may malfunction due to lightning or radio.
If the air conditioner malfunctions, turn off the power with the circuit breaker and restart the
operation with the remote controller.
NOTE
