4.1 Unpacking and Placement

• Carefully remove the machine from its packaging.
• Place the machine on a stable, level surface capable of supporting its weight.
• Ensure there is adequate clearance (at least 15 cm or 6 inches) around all sides for proper ventilation.
• Avoid placing the machine near heat sources or in direct sunlight.

4.2 Initial Cleaning

Before first use, thoroughly clean all parts that will come into contact with food.

1. Remove the dispensing handles, dispensing valves, and mixing shafts.
2. Wash these components with warm, soapy water and rinse thoroughly.
3. Wipe down the hoppers and the interior of the dispensing area with a damp cloth.
4. Ensure all parts are completely dry before reassembly.

4.3 Power Connection

• Verify that the power supply matches the machine's requirements (e.g., 1250W, specific voltage).
• Plug the power cord into a dedicated, grounded electrical outlet.

5. Operation

5.1 Preparing the Ice Cream Mix

• Prepare your desired soft serve ice cream mix according to its specific instructions.
• Ensure the mix is thoroughly blended and free of lumps.
• Pour the prepared mix into the two 4-liter mixing hoppers. Do not overfill.
• Close the hopper lids securely.

5.3 Pre-cooling and Fresh-keeping Function

• The pre-cooling function helps to quickly lower the temperature of the mix in the hoppers, reducing the time required for ice cream production.
• To activate the fresh-keeping function, press the "Keep Fresh" button on the control panel. This function maintains a low temperature in the hoppers, preserving the freshness of the ingredients overnight or during periods of inactivity.

5.4 Adjusting Hardness

The hardness of the ice cream can be adjusted via the control panel. Refer to the specific settings menu on the LCD panel to increase or decrease the freezing intensity, thereby altering the ice cream's consistency.

5.5 Material Shortage Alarm

The machine is equipped with a material shortage alarm. When the mix level in a hopper is low, an alert will sound or display on the panel. Add more ice cream mix promptly to prevent the machine from running dry, which can cause damage to internal components.

6. Maintenance

6.1 Daily Cleaning (Automatic Cleaning)

The machine features an automatic cleaning function for daily sanitation.
