- Drainage Setup (Choose one method):
- Manual Drainage (Water Tank): The dehumidifier will collect water in its internal 95oz (approx. 2.8L) water tank. When the tank is full, the unit will automatically shut off and an indicator light will illuminate. Remove the tank, empty the water, and reinsert it to resume operation.

Route the hose to a suitable drain (e.g., floor drain, sink). Ensure the hose is sloped downwards to allow gravity drainage.
