3. Setup and Installation
Dehumidifier Placement
- Place the dehumidifier on a firm, level surface in an area where the humidity is highest.
- Ensure there is at least 8 inches (20 cm) of space around the unit for proper air circulation. Do not block the air inlet or outlet.
- Avoid placing the unit near heat-generating appliances or in direct sunlight.
Power Connection
Plug the dehumidifier into a dedicated, grounded 115V/60Hz electrical outlet. Do not use extension cords or power strips.
Water Drainage Options
The Midea dehumidifier offers two methods for water removal:
A. Manual Drainage (Water Bucket)
The unit will collect water in its internal bucket. When the bucket is full, the unit will automatically shut off and illuminate the 'Full' indicator. Empty the bucket and replace it securely to resume operation.
B. Continuous Drainage
For continuous operation without needing to empty the bucket, you can connect a standard 0.75-inch female garden hose (not included) to the continuous drain port on the back of the unit. Ensure the hose is sloped downwards to allow gravity drainage to a suitable floor drain.

The Eastman 60309 drain hose, with its 3/4-inch female hose thread, may be compatible for continuous drainage if its open end can be directed to a drain. Verify compatibility before use.
