3.1 Unboxing

Carefully unbox your SUNLU FilaDryer S4. Ensure all components listed in the packing list (Figure 2.8) are present. The unboxing process is demonstrated in the video below.

3.2 Suidheachadh corporra

1. Install PTFE Tube: Insert the provided PTFE tubes into the designated filament exit holes. Push firmly to secure.
2. Place Filament: Open the top cover by pulling the safety lock latch back. Place up to four 1kg filament spools inside the dryer.
3. Filament beathachaidh: Thread the filament through the installed PTFE tubes. You can use either the top holes or side holes depending on your printer setup.
4. Dùin an Còmhdach: Dùin am mullach còmhdach gu tèarainte.

3.3 Cumhachd Air adhart

Connect the power cable to the dryer and plug it into a power outlet. Flip the main power switch to the 'ON' position. The display screen will illuminate.

4. Stiùireadh Obrachaidh

The FilaDryer S4 features an intuitive touch screen interface for easy operation. Refer to the screen function introduction video for a visual guide.

4.1 Basic Operation (Manual Mode)

1. Suidhich Teòthachd: Use the 'SET' button to navigate through settings. When the temperature value flashes, use the up/down arrows to adjust the desired drying temperature (35-70°C).
2. Suidhich an ùine tiormachaidh: When the time value flashes, use the up/down arrows to set the drying duration (0-99 hours).
3. Tòisich a’ tiormachadh: The dryer will automatically begin heating once settings are confirmed.

4.2 Intelligent Drying Modes

The FilaDryer S4 offers intelligent drying modes based on real-time humidity monitoring:

• Automatic Stop (RH ≤ 25%): The dryer will stop heating and drying when the internal relative humidity drops to 25% or below.
• Power Saving Storage Mode (25% < RH < 50%): The dryer maintains thermal insulation to keep filaments dry without continuous heating.
• Automatic Start (RH ≥ 50%): If the humidity rises to 50% or above, the dryer will automatically re-heat and re-dry the filaments.

4.3 Filament Type Presets

The dryer has recommended temperature settings for various filament types. You can select the filament type on the screen, and the dryer will suggest optimal parameters (refer to Figure 2.5).

5. Cumail suas

To ensure the longevity and optimal performance of your FilaDryer S4, regular maintenance is recommended:

• Taobh a-staigh Glan: Periodically wipe the interior of the dryer with a dry, soft cloth to remove any dust or filament debris.
• Check PTFE Tubes: Inspect the PTFE tubes for any wear or blockages. Replace if necessary to ensure smooth filament feeding.
• Desiccants: The S4 has two compartments for storing desiccants. Ensure desiccants are fresh and replace them as needed to maintain low humidity levels for storage.

6. A ’dèanamh trioblaid

If you encounter issues with your FilaDryer S4, consider the following common problems and solutions:

• Filament Still Moist After Drying:
  • Ensure correct temperature and time settings for your filament type.
  • Verify that the dryer is properly sealed and there are no significant air leaks.
  • Check the condition of desiccants if used for storage.
• Tiormaiche gun teasachadh:
  • Confirm the power cable is securely plugged in and the main switch is on.
  • Check the set temperature; ensure it's above the ambient temperature.
  • If an error code (e.g., ER3) appears, it might indicate a sensor issue. Contact customer support if the problem persists after checking connections.
• Filament Snagging/Breaking:
  • Ensure PTFE tubes are correctly installed and not kinked.
  • Verify filament is properly spooled and not tangled inside the dryer.
