When the Need Arises When the Need Arises
Air conditioner
Discharge air temperature is low
Case Description / what to check
High-temperature discharge air is not
supplied during HEAT PLUS operation.
• When the outdoor temperature is low, and falls below freezing point, discharge air temperature
may be unable to reach a suf cient value.
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 airow 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”.

• Signal communication may be disabled if an electronic-starter-type uorescent 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.
• It is possible for any electronic devices that generate signals or infrared rays such as
smartphones and game consoles placed near the unit. The signals coming from electronic
devices can interfere with the remote control signal.
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”.

“ ” 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 “
” 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 airow.
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 DAIKIN EYE 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 airow 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.
The ON/OFF TIMER does not
operate according to the settings.
• Check if the ON/OFF TIMER and the WEEKLY TIMER are set to the same time.
Change or deactivate the settings in the WEEKLY TIMER.
