2. Safety Information

• Leveling: Ensure the cabinet is placed on a stable, level surface to prevent tipping and ensure proper operation. Adjust the leveling feet as needed.
• Movement: Do not move the cabinet while it is in operation or contains items, as this may damage the unit or its contents.
• Power Supply: Use only the included multi-voltage power supply. Do not attempt to use other power adapters.
• Ventilation: Ensure adequate air circulation around the cabinet to allow for efficient heat dissipation from the dehumidifying unit.
• Internal Temperature: The cabinet regulates humidity, not temperature. Avoid placing it in areas with extreme temperature fluctuations.

3. Setup

1. Unpacking: Carefully remove the dry cabinet from its packaging. Inspect for any signs of damage during transit.
2. Handle Installation: The door handle is typically installed on the inside for shipping protection. Remove the handle from the inside of the door and securely attach it to the outside using the provided screws.
3. Leveling: Place the cabinet in its desired location. Adjust the four feet, especially the two leveling feet, to ensure the cabinet is stable and level on uneven surfaces.

5. Maintenance

• Cleaning: Wipe the exterior of the cabinet with a soft, damp cloth. For the glass door, use a glass cleaner. Avoid abrasive cleaners that could scratch surfaces.
• Interior Cleaning: Periodically remove items and wipe down the interior surfaces and shelves with a dry or slightly damp cloth. Ensure the interior is completely dry before placing items back inside.
• Gasket Seal: Check the door's gasket seal regularly for any signs of wear or damage. A proper seal is crucial for maintaining consistent humidity levels.
• Power Cord: Inspect the power cord for any damage. If damaged, discontinue use and contact customer support.

6. Troubleshooting

• Humidity Not Changing:
  • Ensure the door is fully closed and the gasket seal is intact.
  • Verify the power supply is connected and the unit is powered on.
  • Allow sufficient time (1-3 hours) for the humidity to adjust after setting.
  • Avoid frequent opening of the door, which can disrupt internal humidity.
• Display Not Working:
  • Check the power connection.
  • Ensure the power outlet is functional.
