CAUTION: Plumbing
All plumbing work should be done according to local plumbing code.
CAUTION: Installation
CAUTION: Servicing
Disconnect main power before any servicing.
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.
Nortec 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 Nortec.
Plumbing to be performed by a licensed plumber.
Drain water from humidifier can be very hot. Do not drain to public sink.
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 RH2 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.

Introduction
Receiving and Unpacking Equipment
Check packing slip to ensure ALL material has been delivered. Each humidifier may be shipped
in more than one box.
All material shortages are to be reported to NORTEC within 48 hours from receipt of goods.
NORTEC assumes no responsibility for any material shortages beyond this period.
Inspect boxes for damage and note on shipping waybill accordingly.
After unpacking, inspect equipment for damage. If damage is found, notify the shipper promptly.
All NORTEC products are shipped on an F.O.B. factory basis. Any and all damage, breakage, or loss
claims are to be made to the shipping company.
Location of Humidifier’s Manifold in an Air Conditioning System
Although SAM-e distribution systems are designed to provide drip-less humidification, several operating
factors related to steam supply may result in excess moisture or water collecting in
steam-tube pipe with the potential for water damage. To ensure protection against water damage, best
practice includes either a sealed section of duct or, preferably a drip-pan with drain installed underneath
each unit. In addition, to facilitate maintenance checks and inspections, an inspection cover, inspection
glass or service opening should be installed downstream.
For more information, see SAM-e Engineering Manual [1503529-X].
Notes
Absorption distance: the distance between the SAM-e and the first obstruction (coil, elbow, damper, etc.)
that steam may encounter. Traces of steam may pass the obstruction, but will not condense, leaving
obstructions dry. If any of the duct or air-handling unit (AHU) conditions are changed between design
and installation, calculated absorption distance may change. It is advisable to re-calculate absorption
distance to ensure that SAM-e operates as intended. If changes are required, please contact factory for
assistance.

1
Fasten support brackets to header using 5/16” washers and 5/16” nylon lock-nuts.
2
Place header on duct floor and drill 4 x 1/2” (12.7 mm) holes through floor.
Secure header to floor using fasteners (by others).
Use caulking to seal holes in ductwork.

3
Insert tube into insertion stop washer and then into grommet.
Wetting grommet with water will make assembly easier.
Ensure nozzles face the sides of the duct (perpendicular to air flow).
4
Assemble remaining tubes in same way.
