Drain connection
CAUTION:
Water drain installation should conform to local codes and regulations. Any installation work
must be carried out by suitably qualified personnel.
Drain connection specification:
Evaporation chamber water drain temperature: 60
C.
Standard hydraulic compression fittings: a 20mm (evaporation chamber drain) and a 15mm (Pan drain).
2 hydraulic threaded fitting located under the humidifier (see Illus. 29) must be connected to the drain pipe.
Use standard copper hydraulic pipes 20mm and 15mm.
Ensure that the drain pipe dimension is sufficient, especially if more than one humidifier is evacuating into
the same drain line.

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.
