COOLING OPERATION
• If cooling is started at an AUTO or HI fan speed
setting, and if a considerable difference is present
between the room temperature and preset
temperature, the damper inside of the bottom air
outlet will automatically open to allow cold air to
also be directed out of the bottom side air outlet.
When the room temperature reaches the preset temperature or after approximately 30 minutes have elapsed from
starting operation, cold air will automatically be directed only from the top side air outlet.
• When it is desirable to direct cold air from the bottom side air outlet for a longer period of time, set the temperature
at 16°C and fan speed at HI. When the room temperature is more than 8°C above the preset temperature (16°C),
cold air will continuously blow from the bottom side air outlet.
DEHUMIDIFYING OPERATION
• For more efficient dehumidifying, the bottom side air outlet will remain closed.
FAN OPERATION
• Air blows out only from top side air outlet.
AIR OUTLET SWITCH IS SET TO
• Air blows out only from top side air outlet in both heating and cooling operation.
• Air can be blown only from top side air outlet, to prevent blowing air striking your face during sleep, etc.
• If air blows out only from the top side air outlet, it takes more time to reach the set temperature when compared to
air blowing from both top and bottom side air outlets. Also, temperature distribution within the room may be adversely
affected. It is therefore recommended to use both top and bottom side air outlets whenever possible.

OPERATION lamp
This lamp lights during operation.
During heating, the operation indicator may blink, blowing
very lightly or totally stopping under the following
conditions:
(1) During preheating (heating operation)
For about 2~3 minutes after start up.
(2) During defrosting (heating operation)
Defrosting will be performed about once an hour when
frost forms on the heat exchanger of the outdoor unit,
for 5~10 minutes each time. (If the piping length used
is longer than usual, frost will likely to form.)
