1. Introduction
The Panasonic WhisperGreen Select Dual Speed Ceiling Mount Exhaust Fan (Model FV-0511VKS2) is designed to provide efficient and quiet ventilation for various rooms in your home. This fan operates at an "always on" low speed to maintain fresh air and can increase to a higher speed when activated by a switch or sensor, automatically returning to low speed after a user-set time. Its superior performance exceeds industry standards set by ASHRAE and ENERGY STAR, offering certified CFM performance at 0.5 w.g. and low sone levels. The Flex-Z Fast Bracket simplifies installation, allowing for easy positioning without attic access and supporting both 4" and 6" ducting. This manual provides essential information for the safe and effective setup, operation, and maintenance of your fan.

4. Operating Instructions
The WhisperGreen Select fan offers dual-speed operation and customizable airflow settings to suit your needs.
4.1. Multi-Speed CFM Operation
The fan operates quietly at an "always on" low speed to maintain fresh air. It increases to a higher speed when activated by a switch or sensor, then automatically returns to low speed after a user-set time.

4.2. Customizable with Add-On Modules
The Panasonic WhisperGreen Select fans can accommodate up to 3 add-on modules (sold separately) to create a system tailored to your specific needs. These modules include Smart Action Motion Sensor, Condensation Sensor, and Multi-Speed with Time Delay.

4.3. Understanding CFM and Sones
CFM (Cubic Feet per Minute) indicates the volume of air moved by the fan, directly correlating to its power and suitability for room size. Sones measure the sound level of the fan, with lower sone ratings indicating quieter operation.

5. Maintenance
Regular maintenance ensures optimal performance and longevity of your exhaust fan. Always disconnect power before performing any maintenance.
- Cleaning the Grille: Periodically wipe the grille with a soft, damp cloth to remove dust and debris. Do not use abrasive cleaners.
- Cleaning the Fan Blade: If necessary, remove the grille and carefully wipe the fan blade with a damp cloth. Ensure the blade is dry before reassembling.
- Motor Lubrication: The fan motor is permanently lubricated and requires no additional oiling.
- Ductwork Inspection: Annually inspect the ductwork for any blockages or leaks that could reduce fan efficiency.
6. Troubleshooting
If you experience issues with your fan, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Fan does not operate. | No power, loose wiring, tripped circuit breaker. | Check power supply, ensure all connections are secure, reset circuit breaker. |
| Fan is noisy. | Loose mounting, dirty fan blade, ductwork obstruction. | Ensure fan is securely mounted, clean fan blade, check ductwork for obstructions. |
| Low airflow. | Dirty fan blade/grille, ductwork obstruction, incorrect CFM setting. | Clean fan blade and grille, clear ductwork, verify CFM setting is appropriate for room size. |
| Excessive vibration. | Unbalanced fan blade, loose mounting screws. | Inspect fan blade for damage or debris, tighten all mounting screws. |
