Operation
Red LEDs are light together.
2. Ice-making Status: The compressor, motor fan and pump are on. The hot gas valve is off. When the green
LED is lit, the unit is working in the ice making mode controlled by a temperature probe on the evaporator.
When the green LED is flashing, the unit is working in the ice making mode controlled by a fixed timer. The
fan motor is also controlled by the condenser sensor. When the ambient temperature is too low, the motor
fan stops working.
3. Ice Harvest Status: The pump is off. The hot gas valve, compressor and motor fan are on. The fan motor
is also controlled by the condenser sensor. When the ambient temperature is too low, the motor fan stops
working. The Yellow LED indicates the ice harvest status.
4. Ice Full Status And Cold Preservation Stage: If the ice bin is filled with ice, the machine stops making
ice and turns to the cold preservation stage automatically. In this stage, the compressor works regularly
to keep the low temperatures so ice does not melt. The rest of the electric components are off. The
WHITE LED indicates the ice full status and the GREEN AND YELLOW LEDs together indicates the cold
preservation status.
5. Cleaning Status: Turn the machine’s CLEAN SWITCH to CLEAN for 3 minutes after the POWER SWITCH
is turned on. At this stage, the pump is on. Compressor, motor fan and are off. The GREEN and YELLOW
LEDs are flashing together. To stop the cleaning mode, turn the machine “OFF” or the unit will turn off
automatically after 30 minutes. NOTE: In order to start the Clean Status the unit must be on. The CLEAN
switch must be turned on within 3 minutes before the COMPRESSOR starts. Do not turn the CLEAN switch
on when machine is in ice-making status or ice-harvest status.
CONTROLLER BOX
Instructions for LEDs and buttons:
1. White LED: Ice full indicator light. When this LED is lit, the ice storage bin is full of ice or there is something
between the ice-full sensor and the evaporator. The unit will stop making ice. When ice cubes are taken out
of the ice storage bin making the ice-full probe free, the white LED will flash for 3 minutes. Then the unit will
restart and return to the ice making mode.
2. Green LED: Ice making indicator light. When this LED is lit, the unit is working in the ice making mode
controlled by a temperature probe on the evaporator. When the green LED is flashing, the unit is working in
the ice making mode controlled by a fixed timer.
3. Yellow LED: Ice harvest indicator light. When this LED is lit, the unit is working in the ice harvest mode
controlled by ice-full probe. When green LED and yellow LED is lit, it means the unit is working in the cold
preservation stage .
4. Red LED: power indicator light. The unit is on when the red LED is lit.
5. Mode button: Mainly for service. When this button is pressed, it can change from ice making mode to ice
harvest mode, or from ice harvest mode to ice making mode. You can see the change of the mode from the
status of the green and yellow LEDs.
NOTE:
If during the ice size adjustment, the “BIN FULL”, “ICE” and “HARVEST” LEDS blink all at once, this
indicates that the unit is in the default factory setting of the ice size adjustment.
