4. Setup

4.1 Placement

Place the dehumidifier on a level surface in the desired area. Ensure there is at least 12 inches of clearance around all sides for optimal airflow.

4.2 Drainage Options

The unit offers two drainage methods: gravity drainage and pump drainage.

• Gravity Drainage: Connect the included drain hose to the drainage outlet. Ensure the hose is sloped downwards to allow water to flow continuously to a suitable drain (e.g., floor drain, sink). The drain hose is 9.84 ft long.
• Pump Drainage (Optional): For long-distance or upward drainage, an external condensate pump (not included) can be connected. This allows water to be pumped up to 19.6 ft vertically.

4.3 Ducting (Optional)

The dehumidifier's air outlet is duct-able, allowing for directed airflow. This is useful for targeting specific areas or for more controlled air circulation.

4.4 Hanging Installation (Optional)

For crawl spaces or basements with limited floor space, the dehumidifier can be hung using optional hanging kits (not included).
