Weather Proof
Enclosure
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.
