5. Water Drainage
The dehumidifier offers two methods for water removal:
- Manual Drainage (Water Tank): The unit collects water in its 2-liter transparent tank. When the tank is full, the unit will automatically shut off and an indicator light will illuminate. Carefully remove the tank, empty the water, and reinsert it.
- Continuous Drainage (Hose): For uninterrupted operation, attach the included 2-meter drainage hose to the continuous drainage port on the back of the unit. Route the hose to a suitable drain (e.g., floor drain, sink). Ensure the hose is sloped downwards to allow gravity to drain the water.

6. Anti-Freeze Protection
The unit features an automatic anti-freeze system. If the coils begin to freeze due to low temperatures, the dehumidifier will automatically activate defrost mode to prevent damage and ensure stable operation in cooler environments.

7. Memory Protection
In the event of an unexpected power outage, the dehumidifier will remember its last settings. Once power is restored, the unit will automatically resume operation with the previously selected mode and humidity level, eliminating the need for manual reset.
