   • The ambient temperature, water temperature, and pressure of the water supply meet the above requirements.
2. Startup: turn on the power switch. After power-on, the machine begins to make ice automatically.
3. For normal operation, please confirm:
   • There is water in the water trough and no overflow occurs;
   • The pump is working properly and water is flowing evenly in the evaporator;
   • The compressor is running normally, the temperature of the evaporator and the ice making water is gradually decreasing;
   • For air cooled machines, make sure the fan is running normally, and there is stable air flow in the inlet and outlet of the ice machine;
   • The ice machine has no abnormal noise;
   • The ice machine has no abnormal vibration;
   • It takes about 10 to 20 minutes to make one batch of ice, depending on the ambient temperature and the temperature of the water. The higher the temperature is, the longer the ice making will take;
   • Ice cubes can be properly harvested from the machine.

Operation Instructions

• Startup: after proper installation, connect the water source and turn on the power supply to turn on the machine. Please confirm that the machine is operating normally when you turn it on for the first time.
• Self-check: with power on for the first time, the ice maker will do a self-check and pump out any remaining water.
• Preparing: after the ice machine has finished the self-check, the inlet valve opens and the inlet water will flow in until it reaches the set level; then the ice maker will defrost one time.
• Ice making: after pre-cooling for 30 seconds, the water pump starts, the water flows through the evaporator smoothly and evenly, the ice cubes are gradually formed in the ice cube tray.
• Ice Harvest (Drop): after the ice making process finishes and the water pump is turned off, the defrosting valve is turned on. After the hot gas enters into the evaporator for about 1-2 minutes the ice cubes slide from the evaporator into the storage bin.
  • Warning: Do not put your hand into the ice storage bin during the ice-falling process to prevent the ice from hitting your hand!
• Shutdown: The ice maker will stop working when you push the “on/off” button on the control panel during the running process.
• Bin full stop: Once the ice storage bin is filled to a certain height, the ice making process will stop after 40 seconds. There is a sensor at the top of the bin which will trigger this stop in production. In order to maximize the bin space make sure to spread around the ice that piles up in front of the sensor
• Repeat ice-making: When the ice cubes triggering this sensor are moved or taken away, the ice maker will go back to the ice making process within seconds.
