5. Setup

1. Unpack Components: Carefully remove all components from the packaging. Verify that all parts are present according to the packing list.
2. Assemble Support and Nozzle: Attach the adjustable support rod to the main unit. Secure the discharge nozzle to the adjustable support.
3. Connect Tubing: Connect one end of the inlet tubing to your liquid source and the other end to the inlet port of the gear pump. Connect the outlet tubing from the gear pump's outlet port to the discharge nozzle. Ensure all tubing connections are tight and secure to prevent leaks.
4. Place Weigh Pan: Position the weigh pan securely on the designated area of the machine.
5. Power Connection: Plug the power cord into the machine and then into a suitable electrical outlet.

6. Operation

6.1 Control Panel Overview

The control panel allows you to configure filling parameters. It features a display screen, numeric keypad, and function buttons.

6.2 Filling Process

1. Power On: Press the ON/OFF button to power on the machine.
2. Select Weighing Type: On the control panel, select the "Weighting type" mode. For automatic weight-based filling, choose "Auto".
3. Set Target Weight: Use the numeric keypad to enter your desired fill weight. This is the weight of the liquid you want in each container.
4. Tare Function: Place an empty container on the weigh pan. Press the "Tare" button on the control panel to zero the scale. This ensures only the liquid's weight is measured.
5. Adjust Filling Speed: Use the speed knob located on the side of the machine to adjust the flow rate. A slower speed is recommended for highly viscous liquids or smaller containers to prevent splashing and ensure accuracy.
6. Start Filling: Place a container on the weigh pan. The machine will automatically detect the container, perform an automatic tare, and begin dispensing liquid until the preset target weight is reached. The filling process will then automatically stop.
7. Store Data (Optional): The machine allows you to store up to four different sets of filling parameters (A1-A4) for quick access. Refer to the control panel instructions for saving and recalling these settings.

7. Cleaning & Maintenance

Regular cleaning and maintenance ensure the longevity and hygienic operation of your filling machine.

7.1 Cleaning Mode

The machine features a dedicated cleaning mode:

• After completing your filling tasks, activate the cleaning mode via the control panel.
• In cleaning mode, the gear pump will reverse its direction, effectively discharging any remaining material from the inlet and outlet tubing back into your source container. This minimizes waste and simplifies the cleaning of the liquid path.
• Follow up by running a suitable cleaning solution (e.g., warm water for honey, or a food-grade sanitizer) through the system in cleaning mode, then rinse thoroughly with clean water.

7.2 Tube Replacement

The inlet and outlet tubes are designed for easy replacement without requiring disassembly of the pump head. Regularly inspect the tubing for signs of wear, cracks, or discoloration. Replace tubes as needed to maintain hygiene and prevent leaks.

7.3 General Cleaning

• Wipe down the exterior of the machine with a soft, damp cloth. Avoid using abrasive cleaners or solvents.
• Ensure the weigh pan is kept clean and free of spills or debris, as this can affect weighing accuracy.
• Do not immerse the main unit in water or any other liquid.
• When not in use, store the machine in a dry, clean environment away from direct sunlight and extreme temperatures.
