3. Setup

3.1 Unpacking and Initial Placement

1. Carefully remove the dehumidifier from its packaging.
2. Remove any protective materials or tape. Ensure the casters (wheels) are properly installed; they may be located inside the water tank for shipping.
3. Place the unit upright on a flat, stable surface. Allow the unit to stand upright for at least 2-4 hours before plugging it in, especially if it was transported horizontally. This allows the refrigerant to settle.
4. Ensure there is at least 20 cm (8 inches) of clear space around the air inlet and outlet to allow for proper airflow.
5. Position the dehumidifier in a room or area where humidity control is desired. The unit is suitable for rooms up to 77 m² (approximately 350 sq ft).

3.2 Power Connection

1. Ensure the power cord is securely connected to the unit.
2. Plug the power cord into a grounded electrical outlet (220V).

3.3 Wi-Fi Setup (Smart Home Integration)

The Mevagissey dehumidifier can be controlled remotely via a smartphone app. Follow these general steps for Wi-Fi setup:

1. Download the official LEXENT smart home app from your device's app store.
2. Create an account or log in if you already have one.
3. Follow the in-app instructions to add a new device. This typically involves putting the dehumidifier into pairing mode (often indicated by a flashing Wi-Fi light on the control panel).
4. Connect your smartphone to your home's 2.4 GHz Wi-Fi network (5 GHz networks are generally not supported by smart home devices).
5. Enter your Wi-Fi network password into the app.
6. The app will attempt to connect to the dehumidifier. Once connected, the Wi-Fi indicator on the unit will become solid.

Note: Some users may experience difficulties with Wi-Fi connectivity. Ensure your Wi-Fi signal is strong where the unit is placed and that your router settings are compatible with smart home devices.

6. Troubleshooting

If you encounter issues with your dehumidifier, please refer to the following common problems and solutions:

• Unit does not turn on:
  • Check if the power cord is securely plugged into a working outlet.
  • Ensure the water tank is correctly inserted and not full.
• Unit is running but not collecting water:
  • The room temperature might be too low (below 5°C), causing the evaporator coils to freeze. Move the unit to a warmer environment or allow it to defrost.
  • Ensure the air filters are clean and not obstructed.
  • Verify that the desired humidity level is set lower than the current room humidity.
• Unit is making a loud beeping sound:
  • This typically indicates that the water tank is full and needs to be emptied.
• Wi-Fi connection issues:
  • Ensure your smartphone is connected to a 2.4 GHz Wi-Fi network during setup.
  • Check your Wi-Fi signal strength at the unit's location.
  • Restart your router and the dehumidifier, then attempt to reconnect via the app.
  • Refer to the app's troubleshooting guide for specific error messages.
• Reduced air purification effectiveness:
  • Clean or replace the air filters as per maintenance instructions.
  • Ensure the UVC lamp is activated.
