Description of Components
Table 5: Humidifier Components
Disperses steam generated by the humidifier directly into a space being
humidified. Consists of a steam distributor, fan, power supply, and
mounting bracket.
Provides a connection to return condensate to humidifier.
Terminal strip for connecting external controls to humidifier and
interfacing with other equipment.
Power connectors to electrodes in cylinder.
Holds electrodes in water. Current between electrodes generates heat
used to generate steam.
Combines cylinder drain water and fill cup overflow into a single drain
outlet.
Drains water from humidifier.
Controls all functions of the humidifier operation and provides input and
output connections to humidifier components.
Provides an air gap for backflow prevention.
Controls flow of water into humidifier.
High Voltage
Terminal Block
Primary power connection from remote disconnect to humidifier.
Used to detect max water level in cylinder.
Turns power on/off to humidifier controller and drains the cylinder for
servicing. Note: Turn off humidifier disconnect to shut off primary power
to the humidifier.
Turns on/off power to cylinder electrodes based on a signal from the
humidifier’s controller (mounted on control board).
Connect to steam line with steam hose (shown with steam hose to
blower pack).
Steps primary voltage down to 24 VAC for the controller and internal
components such as the fill valve and drain valve.
