4.1 General Description
The Nortec EL/RS Outdoor humidifier is UL-approved for installation outdoors. It is housed in an enclosure
that has an IP54 rating, and comes with built-in heating, ventilation and freeze protection for the plumb-

Figure 2 on page 8
shows the major components of the Nortec EL/RS Outdoor humidifier. The built-in
heating system consists of a heater that is activated during the winter months, and controlled by an
internal thermostat to maintain an appropriate operating temperature inside the enclosure. The heat
control is automatic, and cannot be activated manually.
In addition, a mechanical freeze protection valve drains all the water from the steam cylinder(s), fill cup,
valves and hoses to prevent freeze up when the temperature inside the enclosure drops down to 43 °F
(6 °C).
During warm weather, a weather-shielded exhaust fan moves air through the enclosure to maintain an
appropriate operating temperature. The exhaust fan is automatically controlled by a thermostat, and
cannot be activated manually.
The Nortec EL/RS Outdoor humidifier is also equipped with a remote fault indication board (standard,
not shown) that can be used to remotely monitor the unit.
All other features of the Nortec EL/RS Outdoor humidifier are similar to the Nortec EL/RS humidifier.
