As soon as you select this operation mode by Operation Mode Selection Button, the temperature sensor and built-in microcomputer begin working, controlling the room temperature by choosing among the Soft Dry, Cooling and Heating modes.
[2] Soft Dry Operation Mode pageg
When the room air conditioner is turned on, the Cooling mode is activated to dehumidify the room. A gentle breeze then keeps the room fresh and cool while minimizing fluctuations in temperature. This
mode is designed to be used when temperature is rather cool but the humidity is high,
[I]OFF/ON Dual Setting Timer page 14'--15
Before leaving home in the morning, you can program the room air conditioner to turn itself on just before you return in the evening. Your home is comfortable when you get back without wasting electricity. The room air conditioner can be set in the same way to ensure your maximum comfort when sleeping.

It creates a comfortable sleeping condition.
(Cooling and Soft Dry Operation)
At the start of Sleep Mode, it raises the room temperature by halt a degree Centigrade. One
hour later it raises the temperature half a degree
Centigrade,
(Heating Operation)
At the start of Sleep Mode, it drops the room temperature by 2 degree Centigrade. One hour later it drops the temperature 3 degree Centigracte. The built-in microcomputer then maintains the temperature for eight hours in Cooling and Soft Dry Operation, or five hours in Heating Operation until automatically operation ends. The result is a more
comfortable and invigorating sleep that leaves you

Hot Start Operation: Airflow begins after the temperature becomes warm to avoid undesired cooling effect. Defrosting Operation: Depend on the outdoor temperature, the operation occasionally stops to thaw the frost on the
outdoor unit.
Heat is obtained from outdoor air to warm up the room. When the outdoor ambient air temperature falls, the heating
capacity of the unit might be reduced. We recommend that you use an additional heating device when the outdoor
ambient air temperature is low.
(3) Airflow Direction Procedure
□ Vertical Airflow Direction Control
0Airflow Direction Manual Control
The airflow direction can be adjusted as desired by using the remote control.
This is effective when you want to cool yourself directly, such as when coming out of the bath.
The louvers can be adjusted within a range between the horizontal and 30 degrees downward at Cooling and Soft
Dry Operation, and between the horizontal and 62 degrees downward at Heating Operation.

'Once the power switch has been set to “O" (OFF) the air
conditioner will be set to automatic airflow direction operation when it is set back to “1" (ON),
• Always use the remote control to adjust the airflow direction. Manually moving the vertical airflow direction louver by hand could cause operation errors. If this occurs, set the power switch to “O” (OFF) and then back to T (ON) so that the louver returns to the correct position.
• When air conditioner operation is stopped, the vertical airflow direction louver will close the air conditioner’s air outlet vent.
• During Cooling and Soft Dry operation, do not direct the vertical airflow louvers downward for hours.
If operation continues in this way, condensation may form on the louvers and the air outlet vent,which may cause dripping.

If the Air Filters become damaged
• Purchase replacement filters from your air conditioner dealer.
Cleaning of the air conditioner and the remote control
• Wipe gently with a soft, dry cloth.
Faults
Cause
Airflow does not begin immediately during heating operation.
Operation stops for about 12
minutes during heating. (The operation lamp blinks.)
• If the airflow begins before its temperature become warm, it will cause an undesired cooling effect. In order to prevent this, the airflow will not begin until it is sufficiently warm. (The operation lamp will blink until the airflow begins.)
• This is to thaw the frost which has accumulated on the outdoor unit (defrosting operation). This will take no longer than about 12 minutes, so wait for operation. (Frost accumulates on the outdoor unit when the outdoor temperature is low and the humidity is high.) Water comes out of the outdoor unit.
