It starts when compressor starts operation and it stops 30 seconds aftercompressor stops operation for speed no.8.No. RPM during Fan Speed (rpm)E21D E18D E15D15 75 73 7114 75 73 7113 70 68 6612 68 66 6411 64 62 6010 62 60 609 58 58 588 50 50 507 45 45 456 40 40 405 35 35 354 30 30 303 25 25 252 20 20 201 15 15 158.1.8. Airflow Direction1. There are one types of airflow, vertical airflow (directed by horizontal vane).2. Control of airflow direction can be automatic (angles of direction is determined by operation mode, heat exchanger temperatureand intake air temperature) and manual (angles of direction can be adjusted using remote control).8.1.8.1.

Automatic vertical airflow direction can be set using remote control; the vane swings up and down within the angles as statedabove. For heating mode operation, the angle of the vane depends on the indoor heat exchanger temperature as Figure 1below. When the air conditioner is stopped using remote control, the vane will shift to close position.23CS-E15DTEW CU-E15DBE / CS-E18DTEW CU-E18DBE / CS-E21DTES CU-E21DBE
