  • The air conditioner emits an unpleasant odor.
    • The indoor unit sometimes discharges the room odor remaining inside the unit.
    • Since a very small amount of ozone is generated during the Streamer air purifying operation, you may notice some odor at the air outlet. The amount of discharged ozone is extremely small and causes no health hazards.
    • If mould proof operation is performed and there is an increase in humidity, this may produce an odor.

    Did this solve your problem? If not, please contact your nearest Daikin representative.

  • I lost the remote controller. Can I use the air conditioner without it?

    Operation can be started by pressing the "ON/OFF" button on the main unit. In this case, operation mode and fan speed are set to "automatic."
