wet hands. An electric shock may result.
• Do not spray combustible gas close to the unit. Fire may result.
• Do not place a gas heater or any other open-flame appliance
where it will be exposed to the air discharged from the unit. In-
complete combustion may result.
• Do not remove the front panel or the fan guard from the outdoor
unit when it is running.
• When you notice exceptionally abnormal noise or vibration, stop
operation, turn off the power switch, and contact your dealer.
• Never insert fingers, sticks etc. into the intakes or outlets.
• If you detect odd smells, stop using the unit, turn off the power
switch and consult your dealer. Otherwise, a breakdown, electric
shock or fire may result.
• This air conditioner is NOT intended for use by children or infirm
persons without supervision.
• Young children must be supervised to ensure that they do not
play with the air conditioner.
• If the refrigeration gas blows out or leaks, stop the operation of
the air conditioner, thoroughly ventilate the room, and contact
your dealer.

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 sup-
plied 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 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 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 or more below the set temperature for 15
minutes, the air conditioner switches to heating mode.
Because the room temperature is automatically adjusted in order to
maintain a fixed effective temperature, cooling operation is performed
a few degrees warmer and heating operation is performed a few de-
grees cooler than the set room temperature once the temperature is
reached (automatic energy-saving operation).
5.3. Temperature setting
To decrease the room temperature:
Press button to set the desired temperature.
The selected temperature is displayed .
To increase the room temperature:
Press button to set the desired temperature.
The selected temperature is displayed .
• Available temperature ranges are as follows:
Cooling/Drying: 19 - 30 °C
Heating: 17 - 28 °C
Automatic: 19 - 28 °C
• The display flashes either 8 °C - 39 °C to inform you if the room tem-
perature is lower or higher than the displayed temperature.
(This display does not appear on the wireless remote controller.)
5.4. Fan speed setting
Press the Fan Speed button as many times as necessary while the
system is running.
• Each press changes the force. The currently selected speed is
shown at .
• The change sequence, and the available settings, are as follows.
