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.

Push the bucket back fully so that the lever should not be pushed up.

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 19℉ for 5 minutes, and the ice full switch is off position, the ice tray twisting process will begin.
