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.
