Before you start up the machine, check and confirm the following:

That the packaging tape inside the ice machine has been removed.

All accessories and items in the ice bin have been removed.

The ice machine has been adjusted to a leveled state.

The water pipe has been connected and the water valve is open.

The plug has been connected to the power supply and the power switch is off.

The ambient temperature, water temperature, and pressure of the water supply meet the required conditions.

The ice-making cycle is fully automatic and follows these steps:

Startup: After proper installation, connect the water source and turn on the power supply. The machine will start working.

Self-Check: Once powered on for the first time, the ice maker will perform a self-check and pump out any remaining water.

Preparing: After the machine is energized, the inlet valve will open and water will enter the machine.

Ice Making: After pre-cooling for approximately 30 seconds, the water pump will start. Water will flow through the evaporator smoothly and evenly, and ice cubes will gradually form in the ice cube tray. This process takes about 10 to 20 minutes per batch, depending on ambient and water temperatures.

Ice Harvest (Drop): After the ice making process, the water pump turns off, and the defrost valve turns on. This allows hot gas to enter the evaporator, which causes the ice cubes to slide from the evaporator into the ice bin. WARNING: Keep hands away from the ice bin during the harvest process to prevent injury or contamination.

Shutdown: The ice maker will stop working when you press the “on/off” button on the panel.

Full Bin Auto-Stop: Once the ice bin is filled to a predetermined height, the sliding board cannot reset, and the ice maker will automatically stop. Once ice is removed, the ice maker will turn back on within a few seconds.

The control panel has several functions:

LED Display:

Shows codes for the current operation mode:

• “INI”: Self-Check mode.

• Countdown Timer: Counts seconds during Preparing, Ice Making (until water reaches 32°F/0°C), and Ice Harvest modes.

• “CLE”: Cleaning mode.

• “STL”: Sterilizing mode.

• “RIN”: Rinsing mode.

LED Lamps: Lights indicate the current process (INIT, PREP, MAKE, HARVEST, INLET, FAULT).

Ice Cube Thickness Adjustment: To adjust, press and hold the “-” button for 3 seconds, then use the “+” or “-” buttons to adjust the thickness. Each click adds or removes 1.5 minutes from the ice-making time.

Cleaning: Press and hold the “CLEAN” button for 3 seconds to enter cleaning mode. Cleaning agents are added manually to the water trough.

Switch: Click the ON/OFF button to power the device on or off.

The outer enclosure should be cleaned with a mild detergent and then wiped clean. If necessary, use commercial stainless steel cleaners and polishes. Note that stainless steel may rust without proper maintenance.

Inlet Water Filter (not included):

The filter element should be inspected regularly. It is recommended to replace the filter element every month to every 3 months depending on usage.

Interior Cleaning:

The inside of the ice storage bin can be washed directly with water. Note: Check and confirm the water pressure is lower than the maximum allowed pressure. DO NOT flush the part above the water pump or the evaporator directly for water protection.

Condenser:

The condenser should be cleaned every three weeks. Use a soft brush or a vacuum cleaner with a brush attachment to clean it. Use caution as the edges of the fins are sharp.

The condenser filter should be cleaned every 2 weeks.

Water Pipe:

To ensure food safety, the water pipe of the ice machine should be cleaned regularly.

NOTE: Empty the bin of ice in advance. Clean and sterilize the bin, ice sliding board, water distribution pipe, water supply pipe, water pump, and rinse completely.

1. Turn the ice maker on. Press and hold the “CLEAN” button for 3 seconds; the ice maker will enter clean mode.

2. Add cleaning solution manually and follow the cleaning and sterilizing process instructions.

3. Press the “CLEAN” button. The ice maker will perform an auto clean for about 15 minutes. When complete, the LED display will flash “Clean”.

4. Add sterilizing solution manually and follow the instructions. Press the “CLEAN” button again; the ice maker will enter an auto-sterilizing mode for about 15 minutes.

5. When complete, the ice maker will enter a 5-cycle rinsing process.

6. Once the cleaning process is complete, the ice maker will return to standard ice making mode.

7. Discard the next 5 batches of ice.

To prepare the machine for storage or a period of non-use in cold temperatures, turn off the water and power supply. Then, drain the residual water from the water trough, inlet pipe, and drain pipe.

If the ice machine works abnormally, confirm the following before making a service call:

1. Check the water supply:

Whether there is water in the water trough.

Whether the water pressure for the ice machine is 1.3 Bar to 5.5 Bar; the water temperature is 41-95°F (5-35 °C).

Whether the water valve is open.

Whether there is no water leakage.

2. Check the power:

Whether the panel display is not displaying the OFF standby state.

If the LED on the display panel is blank or “OFF”, check whether the plug and socket are connected properly, and whether the power supply switch is ON.

3. Check nameplate and series number:

Check the nameplate located on the side or back of the ice machine and record the model and series number of the ice machine.

NOTE: If the machine fails due to the user’s faults, such as no water supply, electricity, or environmental factors, rather than the fault of the ice maker, the warranty will be voided.
