IMP RTANT: The service manual is based on the user manual. Before servicing, please
read user manual and service manual carefully. The service operation should be
implemented by qualified technician.

How the Icemaker Works
Please refer to the section “ peration of user manual” from page 13 to 16 . It describes clear
how the icemaker makes ice and uses the water.
There are 3 systems including Cooling System, ater System and iring Connection and
Controller.
Cooling System

NUMBER DESCRIPTION
1 Condenser
2 Multi-connection pipe
3 Hot gas solenoid valve
4 Drier & Filte
5 Capillary tube
6 Hot gas tube
7 Suction tube
8 Compressor
9 Fan motor
9.1 Fan motor support
9.2 Fan blade
10 Discharge tube
19 iring harness
39 Controller box
39.1 Temperature sensor of the condenser
39.2 Temperature sensor of the evaporator
46 Evaporator (Ice Mold)
During the ice-making stage, the hot gas solenoid valve is closed. The hot refrigerant gas is
pumped out off compressor to condenser. The hot gas is cooled by fan forced air to warm liquid
refrigerant after passing through the condenser. The drier & filter reduces the possible dirty and
humidity in the refrigerant. The evaporator is cooled by the refrigerant. So ice can formed on the
evaporator during water is sprayed to the evaporator. Low pressure refrigerant gas may go back
compressor from the evaporator.
During the ice harvest stage, the solenoid valve is open. The hot refrigerant gas is pumped out off
compressor to evaporator through hot gas valve. As the hot gas is not cooled by the condenser, the
refrigerant makes the evaporator (ice mold) warm. So some ice touching the evaporator is thawed.
All of ice can slide down to the ice storage bin.

Water System
hen the water supply pipe is connected with the main water supply, water will fill the water
trough through the floater valve till enough water inside water trough makes floater valve close.
During ice-making stage, water is pumped from the water trough to the water distribution tube. The
distributed water flow the surface of evaporator. Most parts of water go back water trough. Some
water is frozen on the evaporator step by step. The floater valve will open and fresh water is
recruited at any moment.

1. Electrify Status For The First Run
As the icemaker is properly installed. Turn on the water tap, fill the water trough (reach on the level),
then Press the ICE/OFF/ ASH switch to the ICE position. The icemaker will start working
automatically. In this status, the time is fixed about 3 minutes. This function is also helpful to protect
the compressor avoiding restart within 3 minutes.
At this status, the Red, Green, Yellow LEDs are flashing together.
2. Ice-making Status
The compressor, motor fan and pump are powered on. The hot gas solenoid valve is closed.
hen this green LED is lit, the unit is working in the ice making mode controlled by temperature
sensor. hen the green LED start flashing, the unit is working in the ice making mode controlled by
a fixed timer. The fan motor is also controlled by a temperature sensor. And if the ambient
temperature is too low, the motor fan turns off.
3. Ice Harvest Status
The pump is turned off. The hot gas solenoid valve, compressor and motor fan is powered on. The
fan motor is also controlled by temperature sensor. And if the ambient temperature is too low, the
motor fan turned off. The Yellow LED indicates the ice harvest status.
4. Cleaning Status
Press the “ ASH”, Unit switch to Cleaning Status. At this status, only pump is turned on.
Compressor, motor fan and hot solenoid valve are powered off. To stop the cleaning mode, Switch to
“OFF”.
Control Panel
Descriptions of LEDs and buttons:
1. Red LED: Ice Full indicator light.
hen this LED is lit, the ice storage bin is full of ice or there is something between the two
arms of the ice-full sensor in the ice storage bin. The unit will stop working. hen ice cubes
are taken out of the ice storage bin, clearing the sensor, the red LED will keep flashing for 3
minutes. Then the unit will restart and return to the ice making mode.
2. Green LED: Ice Making indicator light.
6
hen this LED is lit, the unit is working in the Ice Making mode controlled by a temperature
probe on the evaporator. hen 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.
hen this LED is lit, the unit is working in the Ice Harvest mode controlled by a temperature
probe on the evaporator. hen the yellow LED is flashing, the unit is working in the Ice
Harvest mode controlled by a fixed timer.
4. Clean button: hen this button is pressed, the unit enters the Cleaning mode. The green and
yellow LEDs flash together. To stop the Cleaning mode, just press the button again.
5. Mode button: Mainly for service. hen this button is pressed, unit can change from Ice Making
mode to Ice Harvest mode, or from Ice Harvest mode to Ice Making mode. You can judge the
mode from the status of the green and yellow LEDs.
6. Adjust button: Mainly for service. hen this button is pressed, the unit will enter the Ice Size
Adjustment mode. The mode can be judged from the status of the green LED.
Ice Size Adjustment Guide:
1.) Press and hold the “Adjust” button for at least 3 seconds. The unit will enter the Ice Size
Adjustment mode. The “ICE MAKING” LED (green) will be blinking continuously during the
ice size adjustment. Release the button when the LED blinks continuously to adjust the ice size.
2.) hile in the Ice Size Adjustment mode, press the “Clean” button or the “Mode” button for
the desired ice size.
Smaller ice setting:
By pressing the “Clean” button, you can decrease the size of the ice cubes. The “ICE FULL”
LED (red) will flash as you lower the ice size and will finally be blinking at the setting of
smallest ice size.
Larger ice setting:
By pressing the “Mode” button, you can increase the size of the ice cubes. The “ICE HARVEST”
LED (yellow) will flash as the larger size is set and will blink when the setting of largest ice size
has been reached.
After 10 seconds without any operation, the unit will automatically memorize the current state and
return to the previous mode.
N TE:
During the ice size adjustment, the “ICE FULL”, “ICE MAKING” and “ICE HARVEST” LEDS
blinking all at once indicate that the unit is in the regular (middle) setting of the ice size.
hen the machine is in the cleaning stage or ice full stage, the ice size is not available for
adjusting.
Major Functions
1. Completely automatic operation.
2. hen the ice storage bin is full, the machine stops making ice automatically. It starts making ice
again once the cubes are removed.

3. The different colors of the LED display indicate various work modes.
4. A sensitive probe and accurate timer enhance the performance of the ice maker.
5. Built-in compressor protection system.
