6. Drainage Options
The dehumidifier offers two flexible drainage methods:
- Manual Drainage (5.5L Water Tank):
When the 5.5L water tank is full, the unit will alert you and stop operation. Carefully remove the tank, empty it, and reinsert it. Ensure the tank is properly seated to resume operation.
- Continuous Drainage (2m Drainage Hose):
For continuous operation without needing to empty the tank, attach the provided 2m drainage hose to the drainage outlet. Ensure the hose is directed downwards to a suitable drain or container, allowing gravity to facilitate water flow.
