3.2 Power Connection

3.3 Drainage Options
The ubbo Z18 offers two drainage methods:
- Manual Drainage: The dehumidifier will collect water in its internal 95oz (2.8L) water tank. When the tank is full, the unit will automatically shut off and alert you to empty it.
- Continuous Drainage: For continuous operation without needing to empty the tank, connect the included drain hose to the drain outlet on the back of the unit. Ensure the hose is routed downwards to a suitable drain (e.g., floor drain, large container) to allow gravity to facilitate water flow.
