Among several ice-maker functions, the ice extraction function is performed by mechanical system. Only the relay
control for a cubed-ice dispensing and the SSR control for the ice chute door are performed electronically.
1) Select Cubed/Crushed/Ice-off function
1-1) The Ice Type button selects Cubed/Crushed/Ice-off options in sequence.
1-2) A default setting is Cubed option.
1-3) If Cubed ice is selected, the Crushed ice bypass solenoid and the geared motor will allow Cubed ice to by pass
the ice Crusher.
1-4) If Ice-off is selected, the ice maker will stop working. This option will be terminated when Cubed and Crushed
options are selected.
1-5) The ice chute door must be open for 5 seconds after dispensing ceases. After this 5 seconds delay, SSR will be
controlled to shut the ice chute door.
2) Water Dispenser function
2-1) To dispense water, depress the water dispenser lever located in the dispenser recess.
2-2) When the lever is depressed, the water solenoid valve located in the machine compartment is open to flow water.
2-3) There is no electronic control function for this option.

According to the ambient temperature, the condenser fan located in the machine compartment is operated with
different modes.
1) Filter Indicator
1-1)This indicator initally lights in green. The light color will be changed to orange after 5 month operation then to red
at the 6th month. The EEPROM in the control board counts a period of time regardless of a power failure.
1-2)To reset the counter and the light color, press Ice Type button and Child lock button for 3 seconds simultaneously.
1-3)If these two buttons are pressed simultaneously for 5 seconds, this function will cease.
1-4)To restore this function, press these buttons again for 3 seconds.
Note) When the Ice-off indicator is on and the remained ice is in tray, only Cubed ice will be dispensed from
the ice bucket.
Note) Do not force to close the ice chute door. Try to dispense some more ice again to work it automatically.
