7714.4 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).14.4.1 Vertical AirflowOperation Mode Airflow Direction Inner Vane Angle (°) Outer Vane Angle (°)1 2 3 4 5 1 2 3 4 5Cooling Auto 10 ~ 45 20 ~ 56Manual 10 15 20 30 45 20 32 44 50 56Soft Dry Auto 10 ~ 45 20 ~ 56Manual 10 15 20 30 45 20 32 44 50 56Heating AutoA 10 20B 30 65C 20 44Manual 8 12 20 40 50 28 36 44 65 721 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. It does not swing during fan motor stop. When the air conditioneris stopped using remote control, the vane will shift to close position.2 Manual vertical airflow direction can be set using remote control; the angles of the vane are as stated aboveand the positions of the vane are as Figure 2 below. When the air conditioner is stopped using remote control,the vane will shift to close position.Side View (Inner Vane)Reference pointStopperClosedPositionStep 1Step 2Step 3Step 4Step 5110ºAMP Air Conditioningwww.ampair.co.uk | sales@ampair.co.uk
