5.4.6 Mounting Checklist
After mounting the humidifier, check the following:
Unit mounted in an outdoor environment where it is not exposed to severe weather, or where the
temperature drops below -40 °F (-40 °C), and where the wind speed does not exceed 100 mph
(160 km/h)?
Adequate clearances maintained (according to
"Location and Suggested Clearances" on page 22
, and all
local and national installation codes)?
Mounting surface stable and reinforced to support the full operating weight of the humidifier?
Unit level?
Unit fastened securely?
5.5 Steam Line Connections
5.5.1 Steam Line
The steam outlet is located on the rear of the Nortec EL/RS Outdoor humidifier – refer to
Figure 2 on
page 8
. Steam hose(s) and clamps are supplied to permit connection to the steam line into the building.
Refer to the Nortec EL/RS manuals for steam and condensate line routing and connection details, as well
as sizing and materials. The number of bends and the length of the line must be kept to a minimum so
that the total system backpressure (backpressure in the line plus duct static pressure) does not exceed
5.5 in H2O (1.37 kPa).
The steam lines can be routed to an air handling unit or through a pipe chase in the roof or exterior wall
into the building.
The steam lines must maintain a constant minimum upslope of 10° or downslope of 2°, and must be
insulated. If the steam line runs upward, a condensate trap must be installed at the location where the
steam exits the unit – refer to
Figure 13
. The condensate line and trap MUST be trace heated to prevent
freezing.
All steam lines MUST be insulated to minimize condensation and maximize efficiency.
