Caution
● Only the Power on indicator lights when the unit is stopped and power supplied to the unit.
● If you press a button for a feature that is not installed in the indoor unit, the remote controller will display the “Not Available”
message.
If you are using the remote controller to operate multiple indoor units, this message will appear only if the feature is not
present at the parent unit.
● When power is turned ON for the first time, it is normal that “PLEASE WAIT” is displayed on the room temperature indication
(For max. 2minutes). Please wait until this “PLEASE W AIT”indication disappears then start the operation.

Wireless remote controller
● When using the wireless remote controller, point it towards the receiver on
the indoor unit.
● If the remote controller is operated within approximately two minutes after
power is supplied to the indoor unit, the indoor unit may beep twice as the
unit is performing the initial automatic check.
● The indoor unit beeps to confirm that the signal transmitted from the
remote controller has been received. Signals can be received up to
approximately 7 meters in a direct line from the indoor unit in an area 45°
to the left and right of the unit. However, illumination such as fluorescent
lights and strong light can affect the ability of the indoor unit to receive signals.
● If the operation lamp near the receiver on the indoor unit is flashing, the
unit needs to be inspected. Consult your dealer for service.
● Handle the remote controller carefully. Do not drop the remote controller or
subject it to strong shocks.In addition, do not get the remote controller
wet or leave it in a location with high humidity.
● To avoid misplacing the remote controller, install the holder included with
the remote controller on a wall and be sure to always place the remote
controller in the holder after use.

NOTE:The sound level is measured in an anechoic room where echoes are few, when compressor stops. The sound
may be bigger than displayed level under actual installation condition by surrounding echoes.The sound level
can be higher by about 2 dB than the displayed level during cooling and heating operation.
