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.
