2. Setup Guide
Follow these steps to set up your dehumidifier for optimal performance.
2.1 Unpacking and Placement
Carefully remove the dehumidifier from its packaging. Place the unit on a level surface in the area where humidity control is desired. Ensure there is at least 8 inches of space around the unit for proper airflow.

2.2 Power Connection
Plug the power cord into a grounded electrical outlet. Ensure the voltage matches the unit's requirements.
2.3 Drainage Options
Your dehumidifier offers two drainage methods: manual bucket emptying or continuous drainage.
2.3.1 Manual Drainage
The unit will collect water in its internal 14.3-pint bucket. When the bucket is full, an indicator alarm will sound, and the unit will automatically shut off. Carefully remove the bucket and empty the collected water.
2.3.2 Continuous Drainage (Built-in Pump)
For continuous operation without manual emptying, connect the included 16.4 ft. pump drain hose to the pump drain outlet. Route the hose to a suitable drain location, ensuring the hose is not kinked or obstructed. The built-in pump can lift water up to 16 feet vertically.

2.3.3 Continuous Drainage (Gravity)
Alternatively, for gravity drainage, connect the 3.28 ft. drain hose (or a standard garden hose) to the gravity drain outlet. Ensure the hose is sloped downwards to allow water to flow continuously to a floor drain or other suitable receptacle.
2.4 WiFi Connection (Optional)
Download the BLACK+DECKER smart app from your device's app store. Follow the in-app instructions to connect your dehumidifier to your home WiFi network. This enables remote control and monitoring.
