- Install the duct connector into the fan housing, ensuring the tabs engage. Connect the 4-inch ductwork to the connector and seal with foil tape.
- Connect the electrical wiring (black to hot, white to neutral, green to ground) inside the wiring enclosure. Secure the wiring enclosure cover.
- Reinstall the blower assembly and wiring panel into the fan housing.
- Plug in the LED module (if applicable) and attach the CleanCover grille by sliding the mounting springs into the slots.
