1. Safety Precautions Read the following “SAFETY PRECAUTIONS” carefully before perform any servicing. Electrical work must be installed or serviced by a licensed electrician. Be sure to use the correct rating of the power plug and main circuit for the model installed. The caution items stated here must be followed because these important contents are related to safety. The meaning of each indication used is as below.
WARNING 19. During installation, install the refrigerant piping properly before run the compressor. (Operation of compressor without fixing refrigeration piping and valves at opened condition will cause suck-in of air, abnormal high pressure in refrigeration cycle and result in explosion, injury etc.). 20. During pump down operation, stop the compressor before remove the refrigeration piping.

13. Operation Control 13.1 Basic Function Inverter control, which equipped with a microcomputer in determining the most suitable operation mode as time passes, automatically adjusts output power for maximum comfort always. In order to achieve the suitable operation mode, the microcomputer maintains the set temperature by measuring the temperature of the environment and performing temperature shifting.
13.1.4.2 Automatic Operation (For Single Split Connection Only) This mode can be set using remote control and the operation is decided by remote control setting temperature, remote control operation mode and indoor intake air temperature. During operation mode judgment, indoor fan motor (with speed of Lo-) is running for 30 seconds to detect the indoor intake air temperature. Every 10 minutes, the indoor temperature is judged.
13.3 13.3.1 Indoor Fan Motor Operation Basic Rotation Speed (rpm) Manual Fan Speed [Cooling, Dry] o Fan motor’s number of rotation is determined according to remote control setting. Remote control ○ ○ ○ ○ ○ Tab Hi Me+ Me Me- Lo [Heating] o Fan motor’s number of rotation is determined according to remote control setting.
13.5 Airflow Direction There are two types of airflow, vertical airflow (directed by horizontal vane) and horizontal airflow (directed by vertical vanes). Control of airflow direction can be automatic (angles of direction is determined by operation mode, heat exchanger temperature and intake air temperature) and manual (angles of direction can be adjusted using remote control). 13.5.1 13.5.1.
13.5.3 Horizontal Airflow (CU-E18RKUA CU-E24RKUA) 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. Operation Mode Vane Angle (°) A Heating with heat exchanger temperature 68 ~ 112 B 90 Cooling and Soft Sry 68 ~ 112 0° Top View A: swing 109.4°F 104.
13.7 Quiet Operation (Heating) Purpose o To provide quiet heating operation compare to normal operation. Control condition o Quiet operation start condition When “POWERFUL/QUIET” button at remote control is pressed. Quiet LED illuminates. o Quiet operation stop condition When one of the following conditions is satisfied, quiet operation stops: Stop by OFF/ON button. Timer “off” activates. POWERFUL/QUIET button is pressed again.
13.10 Auto Restart Control When the power supply is cut off during the operation of air conditioner, the compressor will re-operate within three to four minutes (there are 10 patterns between 2 minutes 58 seconds and 3 minutes 52 seconds to be selected randomly) after power supply resumes. This type of control is not applicable during ON/OFF Timer setting. 13.
2. Circuit Abnormal (Fix Output Lo) a. Abnormal judgment start condition. After ECONAVI and AUTO COMFORT Sensor unit power ON, and after pressed 70 seconds. b. Control content. Judge ECONAVI and AUTO COMFORT Sensor power level every 100ms. c. Abnormal Judgment condition. When ECONAVI and AUTO COMFORT Sensor has continues at Lo level for 25 seconds. 3. Abnormal treatment Any one of the above self-diagnosis result is abnormal Abnormal counter +1 and ECONAVI and AUTO COMFORT Sensor power supply OFF.
ECONAVI Start condition. Press ECONAVI button. ECONAVI Stop condition. Press ECONAVI button again. OFF Timer activates. Press OFF/ON button to turn off the air conditioner. Press AUTO OFF/ON button to turn off the air conditioner. Press POWERFUL/QUIET button. AUTO COMFORT Start condition. Press AUTO COMFORT button. AUTO COMFORT Stop condition. Press AUTO COMFORT button again. OFF Timer activates. Press OFF/ON button to turn off the air conditioner.
13.12.1 Human Activity Sensor Check Mode To enable Human Activity sensor abnormality check mode, during ECONAVI operation ON: Remote control normal mode SET Press continously for 5s SET Transmit ECO demo code and after 30 seconds return to normal mode. TEMP TEMP SET Transmit sunlight sensor check code and after 30 seconds return to normal mode. TEMP TEMP SET Transmit check code and after 30 seconds return to normal mode.
14. Operation Control (For Multi Split Connection) During multi split connection, indoor unit’s operation controls are same with single split connection unless specified in this chapter. 14.1 Cooling operation 14.1.1 Thermostat control Capability supply to indoor unit is OFF (Expansion valve closed) when Intake Air Temperature — Internal setting temperature < 28.4°F.
14.4 Automatic Operation (For Multi Split Connection Only) This mode can be set using remote control and the operation is decided by remote control setting temperature, remote control operation mode, indoor intake and outdoor air temperature. During operation mode judgment, indoor fan motor (with speed of -Lo) and outdoor fan motor are running for 30 seconds to detect the indoor intake and outdoor air temperature. The operation mode is decided based on below chart.
15. Protection Control (E9RK and E12RK) 15.1 15.1.1 30 Seconds Forced Operation Once the air conditioner is turned on, the compressor will not stop within 30 seconds in a normal operation although the intake air temperature has reached the thermo-off temperature. However, force stop by pressing the OFF/ON button at the remote control is permitted or the Auto OFF/ON button at indoor unit.
15.1.5 Compressor Overheating Prevention Control Instructed frequency for compressor operation will be regulated by compressor discharge temperature. The changes of frequency are as below. If compressor discharge temperature exceeds 224.6°F, compressor will be stopped, occurs 4 times per 20 minutes, timer LED will be blinking. (“F97” is indicated.) 224.6oF Compressor = OFF 217.4 F Compressor Frequency Reduce 212oF Compressor Frequency Maintain o 197.6oF 195.8oF 194oF Free Comp.
