5011.4 Airflow Direction• There are two types of airflow, vertical airflow (directed by horizontal vane) and horizontal airflow (directed byvertical vanes).• Control of airflow direction can be automatic (angles of direction is determined by operation mode, heatexchanger temperature and intake air temperature) and manual (angles of direction can be adjusted usingremote control).11.4.1 Vertical AirflowOperationModeAirflowDirectionVane Angle (°)1 2 3 4 5Cooling Auto 10 ~ 40Manual 10 17.5 25 32.5 40Soft Dry Auto 10 ~ 40Manual 10 17.5 25 32.5 40PS9/12PKOperationModeAirflowDirectionVane Angle (°)1 2 3 4 5Cooling Auto 5 ~ 35Manual 5 12.5 20 27.5 35Soft Dry Auto 5 ~ 35Manual 5 12.5 20 27.5 35PS18/24PK• Automatic vertical airflow direction can be set using remote control; the vane swings up and down within theangles as stated above. When the air conditioner is stopped using remote control, the vane will shift to closeposition.• Manual vertical airflow direction can be set using remote control; the angles of the vane are as stated above andthe positions of the vane are as figure below. When the air conditioner is stopped using remote control, the vanewill shift to close position.11.4.2 Horizontal AirflowThe horizontal airflow direction louvers can be adjusted manually by hand.11.5 Timer Control11.5.1 ON Timer ControlON timer can be set using remote control, where the unit with timer set will start operation earlier than the settingtime. This is to provide a comfortable environment when reaching the set ON time.60 minutes before the set ON time, indoor (at fan speed of Lo-) and outdoor fan motor start operation for 30 secondsto determine the indoor intake air temperature and outdoor air temperature in order to judge the operation startingtime.From the above judgment, the decided operation will start operation earlier than the set time as shown below.15 min10 min5 minIndoor intake airtemperature (°C)302530 35Outdoor airtemperature (°C)Cooling / Soft Dry
