Operation Function
2) Preparation of Ice-maker
2-1) Connect the water line to the water supply valve of refrigerator to supply water. (See how to connect a water
supply line in the owner's manual.)
2-2) Push the bucket back fully so that the guide-ice of ice maker should not touch the back of bucket. (If the back of
bucket touches the guide-ice of ice maker, the ice maker will not make ice any more because of a ice full signal.)
2-3) It takes 6 hours to harvest a first ice, and throw away 2-3 times of these ice to make sure the supplied water clean.
1) Initial Operation function
1-1) Whenever the power is on, the control board checks the ice tray leveling with the leveling switch within 2 seconds.
1-2) If the leveling switch is not off position, the geared motor will turn to the initial position to make the ice tray leveled.
1-3) When the ice tray is leveled, it will remain this position for 2 hours (1 cycle time for ice production).
1-4) After 2 hours, the sensor located under the ice tray will measure the tray temperature. If the temperature is
maintained lower than 1℉ for 5 minutes, and the ice full switch is off position, the ice tray twisting process will
begin.
2) Water Supply function
2-1) When the ice tray is levelled again after ejecting ice, the water solenoid valve will be controlled to supply water by
Flow Sensor. (See the "Volume to supply water" Table)
3) Ice production
3-1) After 60 minutes pass from the water supply, the control board will check the temperature.
3-2) If the sensor reads the temperature lower than 1℉ for more than 5 minutes, than the ice production process is
completed.
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 investigated
by this button.
