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 is touched 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.
