Introduction
CAUTION: Servicing
Disconnect main power before any servicing.
The plumbing and electrical compartments contain 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 cylinder, 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
Plumbing to be performed by a licensed plumber.
Drain water from humidifier can be very hot. Do not drain to public sink.
All plumbing work should be done according to local plumbing code.
CAUTION: Installation
Do not mount on hot surfaces
Do not mount in area where freezing can occur
Do not mount on vibrating surface
Do not mount on floor
The NHTC produces steam at atmospheric pressure no devices which could block
steam output should be connected to the steam outlet.
Steam 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.
