5.2 Installation Steps

1. Select Location: Choose an appropriate location on an exterior wall, ensuring it is away from obstructions and allows for proper air exhaust. Consider the fan's dimensions and required clearances.
2. Prepare Wall Opening: Based on the fan's duct diameter (6 inches), create a circular opening through the wall. Use the provided template or refer to the dimensions in Figure 2. Ensure the opening is clean and smooth.
3. Install Ducting: Insert the adjustable telescopic PVC duct through the prepared wall opening. Adjust its length to match the wall thickness.
4. Mount Fan Unit: Secure the main fan unit to the interior side of the wall, ensuring the fan's exhaust aligns with the ducting. Use appropriate mounting hardware.
5. Attach External Grille: On the exterior side of the wall, attach the external vent cover/grille. Ensure it is securely fastened and provides a weather-tight seal.
6. Electrical Connection:
   • Plug-in Option: If using the corded plug, simply plug the fan into a standard 120V/60Hz electrical outlet.
   • Hardwire Option: For permanent installation, a qualified electrician should hardwire the unit to the building's electrical system, following all local codes.
7. Test Operation: Once installed, power on the fan to verify proper operation and airflow.
