If there are no issues with the product, proceed to Step 2. #### Step 2 {#_step_2} A single fan can be connected to air ducting on both ends. Be sure to use ducting of the same diameter to ensure proper airflow. The diameters at both ends of the fan are slightly smaller than the standard size to facilitate connection of the ducting. This is not a size error. ![b8a778ccc1e4717ee2c4a617d835bbd1](https://image.next.vivosun.com/asset/width-695/picture/b8a778ccc1e4717ee2c4a617d835bbd1.png) #### Step 3 {#_step_3} Use a screwdriver to tighten the clamp screws, ensuring the air duct and fan are securely connected. ![fce88234df6c0d824f5c2842d2e0f18d](https://image.next.vivosun.com/asset/width-679/picture/fce88234df6c0d824f5c2842d2e0f18d.png) #### Step 4 {#_step_4} Place the connected product in your desired location.
