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.
