Installation
The Broan-NuTone AER80K is designed for room-side installation, eliminating the need for attic access. This makes it ideal for retrofit, remodeling, and replacement projects.
- Preparation: Ensure power is disconnected at the service panel before starting. Use the provided template to accurately mark and cut the ceiling opening for the fan housing.
- Housing Installation: Insert the fan housing into the ceiling opening. The SnapFit Flange Kit and FoldAway mounting ears facilitate secure placement and a self-trimming finish.
- Duct Connection: Connect the 4-inch ductwork to the EzDuct connector on the fan housing. Ensure a tight seal to prevent air leakage.
- Electrical Wiring: Connect the electrical wiring according to local codes and the wiring diagram provided in the full manual. Ensure all connections are secure. If installing over a bathtub or shower, connect to a GFCI-protected branch circuit.
- Grille Attachment: Once the housing and wiring are complete, attach the CleanCover grille. The design minimizes visible vent slots for a cleaner appearance.

Operating Instructions
The Broan-NuTone AER80K fan operates via a standard wall switch (not included). It is designed for continuous or intermittent operation to manage moisture and odors in your bathroom.
- Turning On/Off: Activate the fan by flipping the connected wall switch to the 'ON' position. Turn off by flipping the switch to 'OFF'.
- Optimal Use: For effective moisture and odor control, operate the fan during and after showering or bathing for at least 15-20 minutes. This helps to clear humid air and prevent mildew growth.
