Installation
This section outlines the general steps for installing the Air King AK80H bath fan. Professional installation is recommended for electrical wiring.
Mounting the Fan Housing
- Prepare Opening: Create an appropriate opening in the ceiling for the fan housing (10.875" L x 9.375" W).
- Attach Hanging Brackets: Utilize the included adjustable hanging brackets to secure the fan housing between ceiling joists. Ensure the housing is level and firmly attached.
- Connect Ductwork: Attach a 4-inch round duct to the fan's duct connector. The connector includes a damper for backdraft protection. Secure the duct with appropriate clamps or tape (not included).
Electrical Wiring
- Disconnect Power: Ensure power to the circuit is OFF at the service panel before proceeding.
- Access Wiring: The fan features a side access panel for easy wiring without removing internal components. Open this panel.
- Connect Wires: Connect the household wiring to the fan's wiring according to local electrical codes. Typically, this involves connecting live, neutral, and ground wires. If installing over a tub or shower, ensure the circuit is GFCI protected.
- Secure Connections: Use appropriate wire connectors and ensure all connections are secure. Close the access panel.
Installing the Grille
- Once the fan housing is installed and wired, attach the grille to the fan housing. Typically, grilles attach with spring clips or screws.

Operation
The Air King AK80H features an integrated humidity sensor for automatic operation.
- Automatic Humidity Sensing: The fan's integrated humidistat continuously monitors the humidity level in the room. When the humidity level reaches a preset threshold, the fan will automatically activate.
- Automatic Shut-off: Once the humidity level drops below the preset threshold, the fan will automatically turn off. This ensures efficient operation and prevents unnecessary energy consumption.
- Quiet Operation: The fan operates at a quiet 1.0 sone level, providing effective ventilation without significant noise disruption.
- Manual Override (if applicable): Depending on your wiring configuration, a separate wall switch may provide manual ON/OFF control, overriding the humidity sensor. Consult your electrician for specific wiring options.
Maintenance
Regular maintenance ensures optimal performance and longevity of your bath fan. Always disconnect power before performing any maintenance.
Cleaning the Grille
- Gently pull down the grille to disengage its mounting springs.
- Wash the grille with mild soap and water. Rinse thoroughly and dry completely before reattaching.
Cleaning the Fan Motor and Housing
- With the grille removed and power disconnected, use a vacuum cleaner with a brush attachment to remove dust and debris from the fan blades and interior of the housing.
- Wipe down surfaces with a damp cloth if necessary. Do not allow water to enter the motor or electrical components.
- Ensure all parts are dry before restoring power and reattaching the grille.
Troubleshooting
If your Air King AK80H bath fan is not operating correctly, consult the following troubleshooting guide:
| Problem | Possible Cause | Solution |
|---|---|---|
| Fan does not turn on. | No power to the unit. Humidity level below threshold. Faulty wiring connection. | Check circuit breaker/fuse. Increase humidity (e.g., run shower) to test sensor. Verify all electrical connections are secure (consult electrician). |
| Fan runs continuously. | Humidity level consistently high. Humidity sensor malfunction. | Ensure proper room sealing and ventilation. If humidity is low and fan still runs, contact customer support for sensor evaluation. |
| Fan is unusually noisy. | Accumulation of dust/debris on fan blades. Loose mounting. Motor issue. | Clean fan blades and housing (see Maintenance). Ensure fan housing is securely mounted. If noise persists, contact customer support. |
| Humidity sensor not responding correctly. | Sensor malfunction or wiring issue. | Verify wiring to the sensor. If issues persist, the sensor may need replacement. Contact customer support. |
