4. Setup
4.1 Unpacking
Carefully remove the dehumidifier from its packaging. Inspect the unit for any signs of damage. Retain the packaging materials for future storage or transport.
4.2 Placement
Place the dehumidifier on a flat, stable surface in the desired room. Ensure there is at least 20 cm (8 inches) of clear space around all sides of the unit for proper airflow. Avoid placing it near heat sources or in direct sunlight.

4.3 Power Connection
Plug the power cord into a grounded electrical outlet. Ensure the outlet meets the power requirements of the dehumidifier.
4.4 Drainage Options
Your dehumidifier offers two drainage methods:
- Manual Tank Drainage: The dehumidifier collects water in its internal 4.2L water tank. When the tank is full, the unit will automatically shut off and the 'Tank Full' indicator will illuminate. Empty the tank by carefully pulling it out from the side of the unit and pouring out the collected water. Reinsert the tank firmly until it clicks into place.
- Continuous Drainage: For continuous operation without needing to empty the tank, connect the included drain hose to the continuous drainage port on the back of the unit. Route the hose to a suitable drain (e.g., floor drain, sink) ensuring it is sloped downwards for gravity drainage.

5.5 Oscillating Mode
Press the Swing button to activate the oscillating function, which helps distribute dehumidified air more evenly throughout the room. Press again to stop oscillation.
5.6 APP and WiFi Control
The dehumidifier can be controlled remotely via a smartphone application. Follow the instructions provided in the separate APP setup guide to connect your device to your home WiFi network. Once connected, you can adjust modes, set humidity, create schedules, and monitor real-time humidity from your phone.
