Operation

MAJOR FUNCTIONS

1. The operating procedure is completely automatic.

2. When the ice storage bin is full of ice cubes the machine stops making ice automatically. It starts making ice again after ice 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. A compressor protection system is built in.

CONTROLLER DISPLAYS

Instructions for LEDs and buttons:

1. Red LED: Ice full indicator light. When this LED is lit, the ice storage bin is full of ice or there is something

between the sensor in the ice storage bin. The unit will stop making ice. When ice cubes are taken out of

the ice storage bin making the ice-full probe free, the red LED will keep ashing 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 ashing, the unit is working in the ice making mode controlled by a xed timer.

3. Yellow LED: Ice harvest indicator light. When this LED is lit, the unit is working in the ice harvest mode controlled by the ice-full probe. When the green LED and yellow LED is lit, it means the unit is working in the cold preservation stage.

4. 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 judge the mode from the status of the green and yellow LEDs.

5. Adjust button: Mainly for service. When this is pressed over 3 seconds, the unit will enter the Ice Size Adjustment mode. The mode can be judged from the status of the yellow LED.

ICE SIZE ADJUSTMENT

1. Press and hold the “Adjust” button for at least 3 seconds. The unit will enter the Ice Size Adjustment mode.

The “HARVEST” LED (yellow) will be blinking continuously during the ice size adjustment.

2. While 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”

LED (green) will ash as you lower the ice size and will nally 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 “BIN FULL”

LED (red) will ash 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 return to the previous mode.

NOTE:

• If during the ice size adjustment mode the “BIN FULL”, “ICE” and “HARVEST” LEDS blink all at once, this

Operation

indicates that the unit is in the regular (middle) setting of the ice size.

• When the machine is in the cleaning stage or ice full stage, the ice size adjustment mode cannot be accessed.

During the ice-making stage, the hot gas solenoid valve is closed. The hot refrigerant gas is pumped out off

the compressor to the condenser. The hot gas is cooled by fan forced air to the warm liquid refrigerant after passing through the condenser. The drier & lter reduces the possible dirt and humidity in the refrigerant. The

evaporator is cooled by the refrigerant. Some ice can be formed on the evaporator during the water spraying process in the evaporator. Low pressure refrigerant gas may go back to the compressor from the evaporator.

During the ice harvest stage, the solenoid valve is opened. The hot refrigerant gas is pumped out off the compressor to the evaporator through the hot gas valve. As the hot gas is not cooled by the condenser, the refrigerant makes the evaporator (ice mold) slightly warm. So some ice touching the evaporator is thawed. All of ice can slide down to the ice storage bin.

WATER SYSTEM

When the water supply pipe is connected with the main water supply, water will ll the water trough through the oater valve until enough water inside water trough makes oater valve close. During the ice-making stage, water is pumped from the water trough to the water distribution tube. The distributed water ows to the surface

of the evaporator. Most parts of water go back to the water trough. Some water is frozen on the evaporator

step by step. The oater valve will open and fresh water is

CIRCUIT DESCRIPTION

First time usage: As the icemaker is properly installed, switch on the water tap, let the water trough ll

(reach full on the level), then press the ON/OFF button on the front panel. The icemaker will start working

automatically In this status, the time is xed to about 3 minutes. This function is also helpful to protect the

compressor from avoiding restart within 3 minutes. At this status, the Red, Green, Yellow LEDs are lit together.

Ice-making status: The compressor, motor fan and pump are powered on. The hot gas solenoid valve is powered off. When this 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 ashing, the unit is working in the ice making mode controlled by a xed timer. The fan motor is also controlled by a condenser sensor. When the ambient temperature is too

low, the motor fan will stop working for good condensation to the refrigerant.

Ice harvest status: The pump is powered off. The hot gas solenoid valve, compressor and motor fan is powered on. The fan motor is also controlled by a condenser sensor. When the ambient temperature is too low, the motor fan will stop working for good condensation to the refrigerant. The Yellow LED indicates the ice harvest status.

Ice full status: If the ice bin is lled with ice or the full sensor is covered, the machine stops making ice

automatically. In this status, the compressor stops working. The RED LED indicates the ice full status.

Maintenance

ADJUSTMENT AND REPLACEMENT

All maintenance to be performed by a certied technician only (call omcan at 1-800-465-0234)

Replace Controller, fuse and the sensor of temperature

ELECTRICAL SHOCK HAZARD

Disconnect electrical power before beginning removal of parts

• Remove the rear cover, front panel,

Troubleshooting

ELECTRICAL SHOCK HAZARD

Turn the unit off and unplug it before beginning to remove any parts.

BEFORE MAINTENANCE

• Make sure the user uses a 115 VAC, 60Hz. only 15amp electrical supply, and make sure that it is properly

grounded to protect the maintainer against electrical shock.

• Check out if the leads loose? Turn off? Short circuit? If you have such problems, foreclose in turn.

Troubleshooting

BASIC CHECKING

If the icemaker has some trouble through the basic checking. The service technician must then check it thoroughly, then maintain accordingly.

HEARING CHECK

• Listen for the user’s depiction about the icemaker during a test run. Try to understand what is the defect and how did the user operate the icemaker before calling for service.

• Is the running sound is normal?

VISUAL CHECK

• Check the pipe of cooling system, especially the welding points. If there is some oil, the gas is leaking out so that no ice making or less ice is produced.

• If the cycle of the ice making and harvest is normal?

• Check the water system, especially the connections. If there is some water leaking?

• Check if the water lter needs to be replaced.

• Check if the icemaker is installed according to the user manual.

• Check if the icemaker needs to be cleaned.

PHYSICAL CHECK

• Touch the hot gas pipe (with the evaporation weld), feeling the temperature. At the ice making stage it should feel cool. At the ice harvest stage it should feel hot.

• Touch the capillary tube (the drier nearby), does it feel lukewarm?
