OPERATING INSTRUCTIONS & INSTALLATION
4) Ice Ejection
It is the movement to separate the ice cubes from the ICE-TRAY after the completion of ice making, which is
conducted by the following steps. Check the changes in status and time for the horizontal S/W (if it is used)
and the ice level check S/W in parallel and then operate Ejection. At this point, the regular rotational direction
of the motors is clockwise (CW) and the reverse rotational direction of that is counter clockwise (CCW).
The Ice Ejection is carried out twice, which is to separate all the ice cubes from the ICE-TRAY.
4-1) Detailed movements by step during the Ejection.
- 1 st step: Ejection temp checking step
Check whether the temp of the temp sensing part is below (1.4°F/-17°C) and whether the Ejection Stand-
By Time after Water Supply has passed. At this point, when the F-Defrost goes into operation during the
Ejection Standby, the Ejection Standby Time will be reset. Then, check that 58~110 min. has passed by
recounting from the beginning after the completion of the Defrost. If the temp of temp sensing part of ice
making become below (1.4°F/-17°C) and maintain it for 5 min, carry on the next step.
- 2 nd step: Filled up ice container checking step
To check the ice level of the ice container, CHECK the ON/OFF (Low/High) of the ice level S/W If the ice
level S/W is ON (Low), it means that the ice container is full and the Ejection stands by. And when the ice
level S/W is turned OFF and 40 min. has passed, the Ejection will be carried out.
- 3 rd step: ICE TRAY overturning step (clockwise)
It is the movement to turn over the TRAY to separate the ice cubes from the TRAY by rotating the Ejection
motor clockwise for a certain time period. At this point, raise the guide ice to prevent the ice cubes from
contacting the guide ice. Carry out the clockwise rotation for a minute from the start of the clockwise
rotation or until the horizontal S/W is ON (Low) after 5 sec from the beginning of the third step when using
horizontal S/W. If the door of the F-Room is open, stop the clockwise rotation and start the rotation after
the door is closed. During the temporary pause, the clockwise rotation will not be counted.
- 4 th step: Ice separating step (Standby for 2 sec. at the maximum twist point )
It is the movement to twist the tray again in the reversed state to separate the ice cubes from the tray
completely and the tray receives torsion because the ICE-TRAY is stopped by the STOPPER. The ice
cubes are separated by this strength and the tray stands by for 2 sec. at the maximum twist point for
complete separation.
- 5 th step: Reverting to horizontal level step (counter clockwise)
Rotate the Ejection motor in reverse to revert the ICE-TRAY to the horizontal level. When using the
horizontal S/W, reverse rotation begins.
When the horizontal S/W is ON (Low) after 5 sec from the beginning of the reverse rotation or the voltage
of the voltage sensing part of the motor is above 0.55V, the rotation will be stopped. At this point, the
raised guide ice becomes lowered again and touches on the highest point of the stored ice for checking
the ice level.
- 6 th step: Motor initializing step (clockwise)
After a sec. upon the completion of the 5
stress of the gear as well as to protect it.
4-2) Errors and handling methods during the ejection
- If the conditions of the completion for the reverse rotation are not satisfied in a min. after applying the
counter rotation during the execution of the 5 steps of the detailed ejection movement, it is considered as
an ERROR and stops the motor.
- If it is judged as an abnormal state, facilitate the initialization in an hour.
If the ejection error occurs 3 times consecutively, it is sensed as ERROR (ICE ERROR) and when
selecting the self diagnosis, it turns on the corresponding LED.
- If the ejection operates normally, the ERROR value of the existing ice making function will be deleted.
th step, the Ejection motor rotates clockwise for 2ms to release the
