Nortec SETC Outdoor - Manual (Page 12)

9 | Installation
Location
The SETC Series Outdoor Models are designed to be rooftop mounted on a roof curb (by others).
When properly installed the outdoor enclosure will provide protection from rain, wind, and snow
in areas with ambient temperature –40 to 104 °F (-40 to 40 °C) and relative humidity 0 - 100%
(non condensing). All models include a ventilation package to prevent overheating in warm
months, and a freeze protection package to prevent freezing in cold months.
 Refer to Figure 5: Installation Location / Clearance for minimum clearance requirements
and to Table 3: SETC Outdoor Specifications for minimum structural requirements.
Ensure mounting surface is strong enough to support the full weight of the humidifier and
accessories.
 The SETC Outdoor is designed to be mounted on a roof curb. Use pipe chase in enclosure
base for routing of services to the humidifier from below. See Figure 6: SETC Outdoor Roof
Curb and Table 4: SETC Roof Curb Depth (Dimension A) for roof curb dimensions and pipe
chase location..
 Install in location where electrical power, boiler steam, and drain can be connected to the
humidifier.
 DO NOT locate the humidifier any further then absolutely necessary from the steam
distributor location as net output will be reduced as a result of heat loss through the steam
line.
 Clearance dimensions shown are for reference only and are the minimum required for
maintenance of the humidifier. Consult local and national codes before final location and
installation. Nortec does not accept responsibility for installation code violations.
