5313.5 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).13.5.1 Vertical Airflow13.5.1.1 CU-RE9SKUA CU-RE12SKUAOperation Mode Airflow Direction Vane angle (°)1 2 3 4 5HeatingAuto with Heat ExchangerTemperatureA 20B 57C 32Manual 20 32 45 57 68Cooling Auto 20 ~ 45Manual 20 26 32 37 45Soft Dry Auto 20 ~ 45Manual 20 26 32 37 4513.5.1.2 CU-RE18SKUA CU-RE24SKUAOperation Mode Airflow Direction Vane angle (°)1 2 3 4 5HeatingAuto with Heat ExchangerTemperatureA 20B 45C 32Manual 20 32 45 57 68Cooling Auto 20 ~ 45Manual 20 26 32 37 45Soft Dry Auto (Anti-Dew Control) 20 ~ 45Manual (Anti-Dew Control) 20 26 32 37 45 Automatic vertical airflow direction can be set using remote control; the vane swings up and down within theangles as stated above. For heating mode operation, the angle of the vane depends on the indoor heatexchanger temperature as Figure 1 below. When the air conditioner is stopped using remote control, the vanewill shift to close position. 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 2 below. When the air conditioner is stopped using remote control, thevane will shift to close position.140°Close position0°122°F86°F96.8°F136.4°FCBAIndoor Heat ExchangerTemperature12345Side ViewFigure 2Figure 113.5.2 Horizontal Airflow (CU-RE9SKUA CU-RE12SKUA)The horizontal airflow direction louvers can be adjusted manually by hand.
