LOCALIZED INSTALLATION AND OPERATION
In this configuration, the central dehumidifier will pull air specifically from a local area, and is typically not ducted to the HVAC
equipment for the whole home conditioning and humidity control. Rather, this application will control humidity in a specific area,
typically a basement or crawlspace.
