Connect the wires with proper gauge matches, ensuring tight connections to prevent overheating. Install the fan motor onto the bracket, aligning it carefully. Secure it with screws and check for smooth rotation. Finally, connect the fan to power, restore cover panels, and test operation. Always verify proper airflow before finalizing.
