Page 3: How The Icemaker Works
How the Icemaker Works Please refer to the section “Operation 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, Water System and Wiring Connection and Controller. Cooling System 6 Hot gas tube NUMBER DESCRIPTION Suction tube 1 Condenser Compressor ... -

- Page 7 Circuit Description 1. Electrify Status For The First Time As the icemaker is properly installed. switch on the water tap, let the water trough full (reach on the level), then turn the ICE/OFF/WASH switch to the ICE position on the front panel. 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 light together. 2. 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 flashing, the unit is working in the ice making mode controlled by a fixed timer. ...
- Page 8 When 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. Ice Size Adjustment Guide: FS‐55IM 1. Press and hold the “Clean” button and the “Mode” button together 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 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 “BIN FULL” LED (red) 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 return to the previous mode. NOTE: During the ice size adjustment, the “BIN FULL”, “ICE” and “HARVEST” LEDS blinking all at once indicate that the unit is in the default factory setting of the ice size. FS‐50IMOD Ice size adjust: Turn the screw clockwise, and the size of individual ice cubes will be larger in the next cycle; the cycle time will be longer. Turn the screw counter clockwise, and the ice size will be smaller in the next cycle. NOTE: It is not a good idea to adjust the ice size often or for no good reason, because the controller may damaged. 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 and proceeds to the cold preservation stage automatically. It starts making ice again after ice cubes are removed. 3.
