4. Setup
- Unpacking: Carefully remove the dehumidifier and all accessories from the packaging. Retain packaging for future storage or transport.
- Placement: Place the dehumidifier on a flat, stable surface in the desired area. Ensure there is at least 8 inches of space around the unit for proper airflow. Avoid placing it directly against walls or furniture.
- Power Connection: Plug the power cord into a suitable electrical outlet.
- Water Tank Installation: Ensure the water tank is correctly inserted into the unit. The dehumidifier will not operate if the tank is not properly seated or is full.
- Continuous Drainage Setup (Optional):
For continuous drainage, remove the plug from the drainage hole at the bottom of the water tank. Insert the provided drain hose firmly into the drainage hole. Route the hose to a suitable drain (e.g., floor drain, large bucket) ensuring it is sloped downwards to allow gravity drainage. Do not allow the hose to kink or be elevated above the unit.
