35Operation Function2) Water Supply function2-1) When the ice tray is leveled again after ejecting ice, the water solenoid value will be controlled to supply water bytime check basis. (See the “Time to supply water” Table)3) Ice production3-1) After 90 minutes pass from the water supply, the control board will check the temperature.3-2) If the sensor reads the temperature lower than -7℃ for more than 5 minutes, than the ice production process iscompleted.4) Test function In order to operate a test function, press the knob (Test Switch) for 1.5 second. This function can be used to check a proper working, to clean the ice tray, and to adjust the water level in the ice tray.4-1) This function only works when the ice tray is leveled and the ice full signal is cleared.4-2) When the water line is connected, each process such as a water supply, ejection, and leveling, can be investigatedby this button.5) Ice off function5-1) When the Ice off option is selected by Ice Type button, the ice making process will cease.5-2) When the ice making process ceases, the final state will be the ice tray with the supplied water.5-3) When Cubed or Crushed option is selected again, the control board will check an accummlated time period.
