Introduction
CAUTION: Servicing
Disconnect main power before any servicing.
Shut off pressurized steam supply and ensure steam pressure is safely relieved
before any servicing of pressurized steam components.
The electrical compartment contains high voltage components and wiring. Access
should be limited to authorized personnel only.
During and following operation of the humidifier, the steam and components in
contact with the steam such as the tank, blower pack, steam lines, steam
distributors, and condensate lines can become hot and can burn if touched.
Walter Meier does not accept any liability for installations of humidity equipment
installed by unqualified personnel or the use of parts/components/equipment
that are not authorized or approved by Walter Meier.
CAUTION: Electrical
All electrical work should be done according to local electrical code.
Electrical connection to be performed by a licensed electrician.
CAUTION: Plumbing / Steam Lines
Plumbing to be performed by a licensed plumber.
Pressurized steam line installation to be performed by a qualified installer.
Drain water from humidifier can be very hot. Do not drain to public sink.
All plumbing and pressurized steam supply line work should be done according to
local plumbing code.
CAUTION: Installation
Internal heaters will not keep the SETC from freezing in cold climates. They are
intended to maintain electronics at a minimum operating temperature for cold
weather startup.
Keep warm and freeze protection must be installed and configured for climates
where there is any risk of temperature falling below 32ºF (0ºC).
The SETC/P produces steam at atmospheric pressure no devices which could
block steam output should be connected to the steam outlet.
Steam output lines must be installed so that no restriction can produce
backpressure in the humidifier.
Regardless of selecting On/Off or modulating control method, Nortec humidifiers
must have a closed circuit across its On/Off security loop control terminal to
operate. Nortec highly recommends the use of a high limit humidistat and an air
proving switch in series for this function.
Unit damage caused by water quality outside of the specified ranges is not
covered under warranty.

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.

Installing on the Curb
If desired sealing material such as caulking or a gasket can be laid on the top of the curb
prior to lifting the SETC into place.
Use the removable lugs installed in the base of the humidifier to lift it into place. Ensure
that the cable/chain/straps used for lifting do not come into contact with and damage the
cabinet. The inside skirt of the base must fit inside the roof curb.
To secure the SETC in place remove the four lifting lugs and insert shims or blocks to fill any
gap between the outside skirt of the base and the curb. Drive screws through the four holes
to secure the unit to the curb.
If the building is positively or negatively pressured the pipe chase opening or the roof curb
opening should be closed around the piping to prevent the building drawing cold air in or
exhausting warm air out through the SETC cabinet.
