Figure 5.1: Diagram showing the fan integrated into ducting, illustrating both exhaust and intake configurations.
- Choose Location: Select a suitable location within your duct system. The fan can be installed in-between sections of ducting or at the end. Ensure there is enough space for the fan and its connections.
- Secure Mounting: Use appropriate mounting hardware (not included) to securely fasten the fan to a stable surface or suspend it within the duct run. Minimize vibration by ensuring a snug fit.
- Connect Ducting: Connect the ductwork to both ends of the fan. Ensure all connections are sealed tightly to prevent air leaks. Duct clamps (not included) are recommended for secure attachment.
- Power Connection: Plug the 5.5-foot grounded power cord into a standard 110/120V electrical outlet. Ensure the outlet is properly grounded.
- Verify Airflow Direction: The fan has an indicated airflow direction (usually an arrow on the housing). Ensure the fan is oriented to move air in the desired direction (exhausting or intake).
