5. Setup
- Unpack the Cabinet: Carefully remove the dry cabinet from its packaging. Inspect for any damage during transit.
- Choose a Location: Place the cabinet on a flat, stable surface. Ensure it is away from direct sunlight, high temperatures, and heat sources.
- Adjust Leveling Feet: The cabinet is equipped with adjustable feet. For models ≥ 50L, there are two front adjustable leveling feet. If the ground is uneven, adjust these feet to ensure the cabinet is level and stable.
- Install Shelves: Insert the adjustable shelves into the desired positions within the cabinet. The shelves slide out for easy viewing and access.
- Initial Operation: It is recommended to run the cabinet empty for more than 8 hours when first using it or after a long period of disuse. This allows the internal humidity to stabilize and reach a lower level.
- Connect Power: Plug the power adapter into the cabinet and then into a suitable power outlet. The digital display will illuminate.

6. Operating Instructions
The AD-80L dry cabinet features a user-friendly digital control panel to manage the internal humidity.
- Power On: Once plugged in, the digital display will show the current internal temperature and relative humidity (RH%).
- Setting Humidity: Use the 'SET' button and the up/down arrows on the control panel to adjust the desired relative humidity level. The control range is typically 25% to 60% RH.
- Dehumidification Process: The cabinet will automatically begin dehumidifying if the measured humidity exceeds your set value. It will stop once the humidity drops below the set value.
- LED Lights: The internal LED lights can be turned ON or OFF using the dedicated button on the control panel. Turning them off helps save energy.
- Loading Items: Place your items inside the cabinet, ensuring they are not blocking the dehumidifying unit or ventilation. The wave sponge can be used for securely holding lenses.

Recommended Humidity Levels for Storage:
| Relative Humidity (RH%) Level | Recommended Items |
|---|---|
| 50%-60% | Books, antique documents, paper, copies, prints |
| 40%-50% | Camcorders, cameras, lenses, telescopes, microscopes, endoscopes, compact discs, film negatives, film transparency/slides, microfilm, disk drives, audio and video tapes |
| 30%-40% | Mental and metal powder products, electrical equipment, semiconductors, capacitors, printed circuit boards, IC, batteries and other electronic equipment, precision measuring tools, spectrometers, optics, lenses |
| 25%-30% | Pharmaceutical raw materials, spices, powder coating, adhesives, seeds, pollen, dry flour |

7. Maintenance
- Door Seal: Regularly check the magnetic door seal to ensure it is clean and free from debris. A tight seal is crucial for effective dehumidification.
- Cleaning: Wipe the exterior of the cabinet with a soft, dry cloth. For the interior, use a slightly damp cloth if necessary, ensuring no moisture enters the electronic components. Do not use abrasive cleaners or solvents.
- Shelf Cleaning: The shelves can be removed and cleaned with mild soap and water, then thoroughly dried before reinserting.
- Long-Term Storage: If the cabinet will not be used for an extended period, unplug it and ensure it is clean and dry before storing.
8. Troubleshooting
- Humidity not reaching target level:
- Ensure the cabinet has been running for at least 8 hours empty for initial stabilization.
- When storing a large quantity of items or items with high moisture content for the first time, it may take at least 3 hours (or longer) to reach the set humidity.
- Check that the cabinet door is fully closed and the magnetic seal is intact.
- Verify that the cabinet is not placed near a heat source or in direct sunlight, which can affect internal conditions.
- Internal temperature cannot be controlled:
- The internal temperature of this digital control humidity dry box can be monitored but cannot be actively controlled or adjusted by the user. It will generally reflect the ambient room temperature.
- Humidity increases after opening the door:
- This is normal. When the door is opened, ambient air with higher humidity can enter the dry box. The longer the door is open, the more the humidity will increase. The cabinet will resume dehumidification to the set level once the door is closed.
- Display not working:
- Check if the power adapter is securely plugged into both the cabinet and the power outlet.
- Try plugging the cabinet into a different power outlet to rule out an issue with the power source.
