Steam Line Connections
Steam generated by the Nortec EL humidifier is not pressurized, but is delivered at atmospheric pressure.
It can be distributed directly into a conditioned space with a built-on or remote-mounted blower pack, or into
an AHU (air handling unit) using Nortec steam distributors or Nortec SAM-e steam distribution manifold.
Read
"Best Practices for Installing Steam and Condensate Lines" on page 26
before installing steam lines.
5.5.1 Steam Distribution Using the Air Handling Unit
For placement of the steam distributor or SAM-e steam distribution manifold in the air handling unit, as
well as best practices and installation procedures, refer to their installation manuals.

Note:
The values in
Table 5
are based on the following nominal conditions: 72°F (22˚C), 40% RH.
Blower pack should not be installed near cold surfaces or where dew point may be reached.
Higher humidity or lower room temperature (compared to nominal conditions stated above) will require increased clearances.
