2. Setup and Installation

2.2 Drainage Methods
Your dehumidifier offers two drainage options: manual drainage using the water tank or continuous drainage with the included hose.
- Manual Drainage: The unit will collect moisture in its internal 5-liter water tank. When the tank is full, the unit will automatically shut off and an indicator light will illuminate. Empty the tank and reinsert it to resume operation.
- Continuous Drainage: For extended use without manual emptying, attach the provided drainage hose to the continuous drain outlet. Ensure the hose is sloped downwards to allow gravity to drain water directly into a floor drain or suitable receptacle.
