Setup
Unpacking and Placement
Carefully remove the dehumidifier from its packaging. It is recommended to let the unit stand upright for at least 24 hours before plugging it in, especially if it was transported on its side, to allow the refrigerant to settle.
Place the dehumidifier on a firm, level surface in the area where humidity control is desired. Ensure there is adequate space around the unit for proper air circulation. Avoid placing it against walls or furniture that could obstruct airflow.

Power Connection
Plug the power cord into a dedicated, grounded 115-volt electrical outlet. Do not use extension cords or power strips.
Water Disposal Options
Your dehumidifier offers two methods for water removal:
- Manual Emptying (Bucket): The unit features a slide-out internal bucket with a 4.2-liter capacity. When the bucket is full, the unit will automatically shut off, and an indicator light will illuminate. Carefully slide out the bucket, empty the collected water, and reinsert it securely.
- Continuous Drainage: For continuous operation without manual emptying, you can connect a standard garden hose (not included) to the continuous drainage port located at the back of the unit. Ensure the hose is sloped downwards to a floor drain or suitable receptacle to allow gravity drainage.
