FEATURES AND FUNCTIONS
INVERTER
At the start of operation, a large power is used to bring the
room quickly to the desired temperature. Afterwards, the
unit automatically switches to a low power setting for economic and comfortable operation.
COIL DRY OPERATION
The Indoor unit can be dried by pressing the COIL DRY button on the Remote Control Unit so as to avoid going moldy
and restrain the breed of bacterium.
AUTO CHANGEOVER
The operation mode (cooling, dry, heating) is switched automatically to maintain the set temperature, and the temperature is kept constant at all times.
WIRELESS REMOTE CONTROL UNIT
The Wireless Remote Control Unit allows convenient control of air conditioner operation.
HORIZONTAL AIRFLOW: COOLING/
DOWNWARD AIRFLOW: HEATING
SWING OPERATION
The airflow-direction louvers move (swing) automatically.
In addition, up, down, left, and right airflow directions can
be selected using the Remote Control Unit.
MILDEW-RESISTANT FILTER
The AIR FILTER has been treated to resist mildew growth,
thus allowing cleaner use and easier care.
SUPER QUIET OPERATION
When the SUPER QUIET button is pressed, the unit begins
SUPER QUIET Operation; the indoor unit’s airflow is reduced
to produce quieter operation.
AUTO FILTER MAINTENANCE FUNCTION
The filter is automatically cleaned after a set amount of time
of air conditioner operation.
INTERNAL UV CLEANING
Growth of mold and various germs inside the indoor unit is
suppressed with UV (ultraviolet rays).
For cooling, use horizontal airflow so the cool air does not
blow directly on the occupants in the room. For heating,
use downward airflow to send powerful, warm air to the
floor and create a comfortable environment.

Each time the button is pressed, the fan speed changes in the following order:
AUTO
About three seconds later, the entire display will reappear.
When set to AUTO:
Cooling : As the room temperature approaches that of the thermostat setting,
the fan speed becomes slower.
Heating : Fan operates so as to optimally circulate warmed air.
However, the fan will operate at very low speed when the temperature of the air issued from the indoor unit is low.
Fan : The fan operates at the low speed.
Example: When set to COOL
Example: When set to 28°C
Super Quiet Operation:

To Stop Operation
Press the START/STOP button (Fig.5 Y).
The OPERATION Indicator Lamp (red) (Fig. 2 6) will go out.
About AUTO CHANGEOVER Operation
AUTO: ● When AUTO CHANGEOVER operation first selected, the fan will oper-
ate at very low speed for about one minute, during which time the unit
detects the room conditions and selects the proper operating mode.
If the differance between thermostat setting and actual room temperature is more than +2 °C → Cooling or dry operation
If the difference between thermostat setting and actual room temperature is within ±2 °C → Monitor operation
If the difference between thermostat setting and actual room temperature is more than –2 °C → Heating operation
● When the air conditioner has adjusted your room’s temperature to near
the thermostat setting, it will begin monitor operation. In the monitor
operation mode, the fan will operate at low speed. If the room temperature subsequently changes, the air conditioner will once again
select the appropriate operation (Heating, Cooling) to adjust the temperature to the value set in the thermostat.
(The monitor operation range is ±2 °C relative to the thermostat setting.)
● If the mode automatically selected by the unit is not what you wish,
select one of the mode operation (HEAT, COOL, DRY, FAN).
About Mode Operation
Heating: ● Use to warm your room.
● When Heating mode is selected, the air conditioner will operate at very
low fan speed for about 3 to 5 minutes, after which it will switch to the
selected fan setting. This period of time is provided to allow the indoor
unit to warm up before begin full operation.
● When the room temperature is very low, frost may form on the outside
unit, and its performance may be reduced. In order to remove such
frost, the unit will automatically enter the defrost cycle from time to
time. During Automatic Defrosting operation, the OPERATION Indicator Lamp (red) will flash, and the heat operation will be interrupted.
Cooling: ● Use to cool your room.
Dry: ● Use for gently cooling while dehumidifying your room.
● You cannot heat the room during Dry mode.
● During Dry mode, the unit will operate at low speed; in order to adjust
room humidity, the Indoor Unit’s fan may stop from time to time. Also,
the fan may operate at very low speed when adjusting room humidity.
Fan: ● Use to circulate the air throughout your room.
During Heating mode:
Set the thermostat to a temperature setting that is higher than the current room
temperature. The Heating mode will not
operate if the thermostat is set lower than
the actual room temperature.
During Cooling/Dry mode:
Set the thermostat to a temperature setting that is lower than the current room
temperature. The Cooling and Dry modes
will not operate if the thermostat is set
higher than the actual room temperature
(in Cooling mode, the fan alone will operate).
During Fan mode:
You can not use the unit to heat and cool
your room.
