4. Setup and Installation
Follow these steps to properly install your fume extraction kit:
- Prepare the Enclosure: Ensure your 3D printer enclosure has a suitable opening for the exhaust kit. The required hose diameter is 70mm. If your enclosure does not have a pre-existing opening, you may need to create one yourself according to the specified size.
- Assemble the Fan Unit: Attach the net cover to the fan unit using the provided screws. Then, secure the flange to the fan unit.
- Mount the Fan Unit: Align the assembled fan unit with the opening on your 3D printer enclosure. Fix it securely in place using the appropriate mounting parts and screws.
- Connect the Exhaust Hose: Attach one end of the retractable exhaust hose to the flange of the mounted fan unit. Use the metal clamp to secure the hose firmly to prevent air leaks.
- Position the Hose: Extend the hose to the desired length, up to 2 meters, and direct the other end to an area where fumes can be safely exhausted, such as out a window or into a ventilation system. The retractable design allows for flexible positioning and space-saving storage when not in use.
- Connect Power: Plug the USB power cable of the fan unit into a compatible USB power source (e.g., a laptop, smartphone charger, or USB wall adapter).

5. Operating Instructions
Operating the YOOPAI Fan Fume Extraction Kit is straightforward:
- Power On/Off: The fan is controlled by an inline USB power switch. Simply press the button on the switch to turn the fan on or off.
- Ventilation: Once powered on, the exhaust fan will begin to draw air from inside the enclosure, effectively removing smoke, odors, and dust.
- Hose Management: Adjust the length of the retractable hose as needed for optimal ventilation and to direct exhaust away from your workspace. When not in use, the hose can be retracted for compact storage.

6. Maintenance
Regular maintenance ensures optimal performance and longevity of your fume extraction kit:
- Fan Cleaning: Periodically inspect the fan blades and protective net cover for dust and debris buildup. Disconnect power before cleaning. Use a soft brush or compressed air to gently remove any accumulated dust.
- Hose Cleaning: If the hose accumulates dust or residue, it can be wiped clean with a damp cloth. Ensure the hose is dry before re-extending or storing.
- Connection Check: Occasionally check all connections, including the hose clamp and mounting screws, to ensure they remain secure.
7. Troubleshooting
If you encounter any issues with your fume extraction kit, refer to the following common problems and solutions:
- Fan Not Turning On:
- Ensure the USB cable is securely plugged into both the fan unit and a working USB power source.
- Check the inline power switch to ensure it is in the "On" position.
- Try plugging the USB cable into a different USB port or power adapter to rule out a faulty power source.
- Poor Fume Extraction:
- Verify that the hose is fully extended and directed to an appropriate exhaust area.
- Check for any obstructions in the hose or fan intake/exhaust.
- Ensure all connections (fan to enclosure, hose to fan) are sealed tightly with the clamp to prevent air leaks.
- Confirm the opening in your enclosure is correctly sized (70mm diameter) and not restricting airflow.
- Excessive Noise:
- While designed for low noise, ensure the fan unit is securely mounted and not vibrating against the enclosure or other surfaces.
- Check for any loose components or debris caught in the fan blades.
