strong direct sunlight, since it can adversely affect
its operation. If the signal receiver window is
exposed to direct sunlight, close a curtain to block
the light.
• Using a fluorescent lamp with a quick starter in
the same room may interfere with transmission of
the signal.
• The unit can be affected by signals transmitted
from the remote control of a television, VCR or
other equipment used in the same room.

• Do not expose the filters to direct sunlight.
(Otherwise they may deteriorate.)
TIPS ON SAVING ENERGY
Below are some simple ways to save energy
when you use your air conditioner.
SET THE CORRECT TEMPERATURE
• Setting the thermostat 1°C higher than the desired
temperature in the COOL mode and 2°C lower
in the HEAT mode will save approximately 10
percent in power consumption.
• Setting the temperature lower than necessary
during cooling operation will result in increased
power consumption.
BLOCK DIRECT SUNLIGHT AND PREVENT
DRAFTS
• Blocking direct sunlight during cooling operation
will reduce power consumption.
• Close the windows and doors during cooling and
heating operations.
SET PROPER AIR FLOW DIRECTION TO OBTAIN
THE BEST AIR CIRCULATION
KEEP FILTER CLEAN TO ENSURE THE MOST
EFFICIENT OPERATION
MAKE MOST OF THE TIMER OFF FUNCTION
DISCONNECT THE POWER CORD WHEN THE
UNIT IS NOT USED FOR AN EXTENDED PERIOD
OF TIME
• The indoor unit still consumes a small amount of
power when it is not operating.
AUXILIARY MODE
Use this mode when the remote control is not
available.
TO TURN ON
Lift the open panel of the indoor unit and press
the AUX button.
• The green OPERATION lamp ( ) on the unit
will light and the unit will start operating in the
