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 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

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

Humidifiers produce 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 duct high limit humidistat.

Pre-installation Check
1. Ensure the total capacity of the humidifier is not higher than the allowable maximum steam
capacity of the distributors used.
ASD/RSD 10: 22 lbs/hr (10 kg/hr)
ASD: 25 lbs/hr (11.3 kg/hr)
BSD: 35 lbs/hr (15.9 kg/hr)
CSD: 115 lbs/hr (52.5 kg/hr)
Steam Line Installation
1. Nortec steam hose should only be used on short steam runs below 10 feet.
2. Ensure that no condensate produced in the steam line will remain trapped. Steam naturally
flows upward and condensate naturally flows downward.
3. See material recommended for use in the chart below. To eliminate the metal corrosion,
nortec does not recommend the use of steel piping.
4. Consult the following pages for step by step distributor installation starting with figure 1.
5. Consult the charts below for steam and condensate sizing guidelines when using steam
