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 neglig ble and is not harmful to your health.
Display lamps

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

The ON/OFF TIMER does not
operate according to the settings.
