Note: By default, the steam outlet, water supply inlet and main drain outlet are on the
left hand side, and the pan drain outlet is located on the bottom of the humidifier. Other
locations of any of these outlets or inlets are available upon request.
Water Drain Valve
The weather proof enclosure is equipped with a normally open valve, enabling the humidifier to drain
all water during a power failure, in order to prevent water from freezing within the unit. During normal
operation, the humidifier reduces drain water temperature to 60°C.
CAUTION: During a power failure, the drain water temperature is not reduced.
Installed drain piping must be rated to 100°C.
