12.4.2 Horizontal Airflow 
•  Automatic horizontal airflow direction can be set using remote control; the vane swings left and right within the 
angles as stated below. For heating mode operation, the angle of the vane depends on the indoor heat 
exchanger temperature as Figure 1 below. It does not swing during fan motor stop. 
 
Operation Mode  Vane Angle (°) 
A 65 ~115 
Heating, with heat exchanger temperature 
B 90 
Cooling and soft dry  65 ~115 
 
 
 
•  Manual horizontal airflow direction can be set using remote control; the angles of the vane are as stated below 
and the positions of the vane are as Figure 2 above.

12.5  Quiet operation (Cooling Mode/Cooling area of Dry Mode) 
• Purpose 
o  To provide quiet cooling operation compare to normal operation. 
 
• Control condition 
o  Quiet operation start condition 
  When “POWERFUL/QUIET” button at remote control is pressed twice. 
POWERFUL/QUIET LED illuminates. 
 
o  Quiet operation stop condition 
  When one of the following conditions is satisfied, quiet operation stops: 
•  POWERFUL/QUIET button is pressed again. 
•  Stop by OFF/ON switch. 
•  Timer “off” activates. 
  When quiet operation is stopped, operation is shifted to normal operation with previous setting. 
  When fan speed is changed, quiet operation is shifted to quiet operation of the new fan speed. 
  When operation mode is changed, quiet operation is shifted to quiet operation of the new mode. 
  During quiet operation, if timer “on” activates, quiet operation maintains. 
  After off, when on back, quiet operation is not memorised. 
 
• Control contents 
o  Fan speed is changed from normal setting to quiet setting of respective fan speed. 
o  Fan speed for quiet operation is reduced from setting fan speed.
