Application Examples
- ASHRAE 62.2 continuous-ventilation projects using the built-in 0/30–70 CFM multi-speed.
- Bathrooms with wall-switch-activated 80 or 100 CFM boost.
- Multi-family residential projects meeting California Title-24 and EarthCraft.
Installation Tips
- Confirm a 120V, 60 Hz circuit and that the duct run is 4" oval or 4" round.
- Use the FV-VS43R 4" oval to 3" round duct adaptor (sold separately) when downsizing to existing 3" round ductwork.
- Pair with the Panasonic Ceiling Radiation Damper (PC-RD06C6, sold separately) for fire-rated ceiling assemblies.
- All electrical work should be performed by a licensed electrician in accordance with local codes.
