Installation Instructions
Proper installation is crucial for the optimal performance and safety of your exhaust fan. It is recommended that installation be performed by a qualified professional.
1. Pre-Installation Considerations
- Location: Choose a ceiling location that allows for proper ducting to the outside. Avoid installing directly over a shower or tub unless specifically rated for such use and protected by a GFCI circuit.
- Ducting: Ensure you have appropriate ductwork (typically 4-inch round) available to connect the fan to an exterior vent cap.
- Wiring: Confirm that a 110V AC power supply is available at the installation site.
2. Mounting the Fan Housing
- Turn off power at the circuit breaker before starting any work.
- Cut an opening in the ceiling according to the fan's rough-in dimensions (refer to product specifications for exact measurements).
- Secure the fan housing to the ceiling joists using appropriate mounting hardware. Ensure the housing is level and securely fastened.

3. Duct Connection
- Connect the appropriate size ductwork (typically 4-inch round) to the fan's exhaust collar.
- Secure the ductwork with duct tape or clamps to ensure an airtight seal.
- Route the ductwork to the exterior vent cap, ensuring minimal bends for optimal airflow.

4. Electrical Wiring
- Remove the wiring compartment cover.
- Connect the household wiring to the fan's wiring according to the wiring diagram provided inside the fan's junction box. Typically, this involves connecting:
- Black (Live) to Black (Fan/Light Live)
- White (Neutral) to White (Fan/Light Neutral)
- Green/Bare (Ground) to Green (Fan/Light Ground)
- Secure all wire connections with approved wire connectors.
- Replace the wiring compartment cover.
5. Grille Installation
- Once the ceiling is finished, insert the grille mounting springs into the slots in the fan housing.
- Push the grille firmly against the ceiling until it is flush.

Operation
The FASDUNT Bathroom Exhaust Fan with LED Light operates via standard wall switches. Depending on your wiring configuration, you may have separate switches for the fan and the light, or a single switch controlling both.
- Fan Operation: Flip the designated wall switch to turn the exhaust fan ON or OFF. For effective moisture and odor removal, operate the fan during and after showering or bathing for at least 15-20 minutes.
- Light Operation: Flip the designated wall switch to turn the LED light ON or OFF. The 5000K LED provides bright, daylight-like illumination.
