Installation Instructions
Follow these steps to replace the spout pressure rod springs in your Donper Ice Cream Machine:
- Power Disconnection: Ensure the ice cream machine is completely unplugged from the power outlet.
- Access the Spout Assembly: Depending on your specific Donper model, you may need to remove the front panel or the spout assembly itself. Refer to your machine's original manual for detailed instructions on accessing this area.
- Locate Old Springs: Identify the existing spout pressure rod springs. These are typically located around the pressure rods that control the flow of ice cream.
- Remove Old Springs: Carefully remove the old springs. Note their orientation and how they were seated, as the new springs will need to be installed in the same manner.
- Install New Springs: Place the new KoelAp DM985YL springs onto the pressure rods. Ensure they are seated correctly and provide the necessary tension. The springs should fit snugly and allow for smooth movement of the pressure rod.
- Reassemble: Reassemble the spout assembly and any panels that were removed. Ensure all components are securely fastened.
- Test Functionality: Once reassembled, plug the machine back in and perform a test run (e.g., with water) to ensure the spout mechanism operates smoothly and without leaks.

Functionality
The KoelAp DM985YL Spout Pressure Rod Springs are critical components in the Donper Ice Cream Machine's dispensing mechanism. They provide the necessary tension to ensure the spout closes properly after dispensing, preventing drips and maintaining hygienic operation. Proper spring tension is essential for consistent product flow and preventing leakage.
Maintenance
- Regular Inspection: Periodically inspect the springs for signs of wear, corrosion, or deformation. Worn springs can lead to improper spout closure and leakage.
- Cleaning: When cleaning the ice cream machine's spout assembly, ensure the springs are also cleaned to remove any residue that could impede their function. Use mild, food-safe cleaning solutions as recommended by the ice cream machine manufacturer.
- Replacement: Replace springs immediately if they show signs of damage or if the spout mechanism is not functioning correctly due to insufficient tension.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Spout drips after dispensing. | Worn, damaged, or incorrectly installed pressure rod springs. | Inspect and replace springs if necessary. Ensure springs are installed correctly and provide adequate tension. |
| Spout difficult to open or close. | Springs are binding or incorrectly seated. | Remove and re-seat the springs, ensuring they move freely on the pressure rods. Check for any obstructions. |
| Inconsistent product flow. | Uneven tension from springs or damaged springs. | Inspect both springs for consistent tension and replace if one appears weaker or damaged. |
