[] When using the wireless remote controller, point it towards the receiver on the indoor unit. [] If the remote controller is operated within approximately 2 minutes after power is supplied

to the indoor unit, the indoor unit may beep twice as the unit is performing the initial auto-

matic 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 blinking, 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 con-

troller on a wall and be sure to always place the remote controller in the holder after use.

Automatic operation [] According to a set temperature, cooling operation starts if the room

temperature is too hot and heating operation starts if the room tem-

perature is too cold.

[] During automatic operation, if the room temperature changes and

remains 2 °C, 4 °F or more above the set temperature for 15 minutes,

the air conditioner switches to cooling mode. In the same way, if the

room temperature remains 2 °C, 4 °F or more below the set tempera-

ture for 15 minutes, the air conditioner switches to heating mode.
