For optimal performance, place the dehumidifier in a location where the humidity is highest and air circulation is good.

Ensure there is at least 8 inches (20 cm) of space around the unit for proper airflow.
Avoid placing the unit near heat sources or in direct sunlight.
Close all doors and windows in the room where the dehumidifier is operating to maximize efficiency.
The unit is designed for residential use in areas such as basements, living rooms, bedrooms, and cloakrooms.

3.3 Drainage Options

The dehumidifier offers two methods for water removal:

Manual Drainage (Water Tank): The unit collects water in its internal 1.92-pint (0.8 gallon) water tank. When the tank is full, the unit will automatically shut off and indicate that the tank needs to be emptied.
Continuous Drainage (Drain Hose): For continuous operation without needing to empty the tank, connect the included 3.9 ft (1.2 m) drain hose to the continuous drain port on the back of the unit. Ensure the hose is sloped downwards to a suitable drain (e.g., floor drain, sink) to allow gravity to remove water.
