4. Setup and Installation
The FASDUNT KEFDKB001-F5 exhaust fan features an integrated design for simplified installation. Please ensure your ceiling opening size is 10.43 x 10.43 inches (26.5 x 26.5 cm) (L x W) for proper fitment.
4.1 Wiring Options
This unit supports two wiring methods for controlling the fan and light:
- Independent Control: Fan and light can be turned on/off separately using two distinct wall switches. This method is recommended to potentially prolong the lifespan of the light.
- Unified Control: Fan and light turn on/off simultaneously with a single wall switch.
Consult the detailed wiring diagrams provided in the included installation manual for specific connections.
Figure 2: Installation Dimensions. This image illustrates the fan's dimensions (10.24 inches by 10.24 inches, 6.89 inches height, 4 inches duct) and specifies a required ceiling opening size of 10.43 x 10.43 inches (26.5 x 26.5 cm).
5. Operating Instructions
Once installed and powered, operate your FASDUNT exhaust fan and light using the connected wall switches.
5.1 Adjusting LED Light Color Temperature
The integrated LED light offers three color temperature options: Warm White (3000K), Daylight (4000K), and Cool White (6000K). To cycle through these options, quickly flip the light switch OFF and then ON again within 15 seconds. Each quick flip will change the color temperature to the next setting.
- First Press: Activates the default color temperature (e.g., Cool White).
- Second Press (within 15s): Changes to the next color temperature (e.g., Daylight).
- Third Press (within 15s): Changes to the final color temperature (e.g., Warm White).
- Subsequent Presses (within 15s): Cycles back to the first setting.
If the switch is left OFF for more than 15 seconds, the light will reset to its default setting when turned ON again.

6. Maintenance
Regular maintenance ensures optimal performance and longevity of your exhaust fan. Always disconnect power at the circuit breaker before performing any maintenance.
- Cleaning the Grille: Remove the grille by gently pulling it down. Wash the grille with mild soap and water, rinse thoroughly, and dry completely before reattaching.
- Cleaning the Fan Housing: Use a soft cloth or brush to remove dust and debris from the fan housing and impeller. Do not use abrasive cleaners or solvents.
- Motor: The motor is permanently lubricated and requires no additional oiling.
The fan housing is constructed from ABS material, which is resistant to rust and corrosion, simplifying long-term care.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Fan does not operate. | No power to the unit. Loose wiring connection. Motor malfunction. | Check circuit breaker and wall switch. Verify all wiring connections are secure (ensure power is off). Contact customer support if motor is faulty. |
| Light does not turn on. | No power to the light circuit. Loose wiring connection. LED module failure. | Check wall switch and wiring. Verify connections (ensure power is off). Contact customer support. |
| Fan is excessively noisy. | Obstruction in fan blades. Loose mounting screws. Ductwork obstruction. | Disconnect power and check for debris. Ensure fan is securely mounted to the ceiling joists. Inspect ductwork for kinks or blockages. |
| Light color changes unexpectedly. | Rapid toggling of the light switch. | This is a feature. To select a desired color, turn the light OFF for more than 15 seconds, then turn ON. Quickly toggle the switch OFF/ON until the desired color is reached. Leave ON for more than 15 seconds to set. |
