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.

Atmospheric SAM-e Steam Lines
Guidelines
1 Nortec steam hose should only be used on short steam runs of less than 10 feet.
2 Ensure that no condensate produced in steam line will remain trapped. Steam naturally
flows upward and condensate naturally flows downward.
3 See material recommended for use in below chart. To eliminate metal corrosion, Nortec
does not recommend the use of steel piping.
4 Consult below charts for steam and condensate sizing guidelines when using steam
distributors.
5 Be sure to include fitting equivalent lengths in total steam run lengths (see below).
In general, match steam-line size to outlet size of distributor.
When using an SETC with less than 15 psig steam supply pressure, a reducer (Nortec part
number 2526110 – 3” to 1.5” reducer or 2526111 – 4” to 3” reducer) is required to
prevent over-sizing of steam lines.
All steam lines should be insulated with at least 1”-thick steam insulation.

Atmospheric SAM-e Condensate Drainage
1 SAM-e condensate outlet connection is male 3/4”-NPT.
2 Condensate from SAM-e must be plumbed to a P-trap. Trap must have center-to-center
height of at least 8”, or 2” more than duct static pressure, whichever is greater. Refer to
typical installation drawings.
3 Condensate from P-trap should drain into a funnel with air-gap prior to entering building
drain.
4 Condensate exits at 212°F (100°C). Local codes may require use of a drain water
cooler (Nortec part number 1710020 - electronic drain water cooler or 1710010 – selfactuated drain water cooler). Refer to installation manual that accompanies drain water
cooler for plumbing details.
5 When collecting condensate, ensure that each device has an air-gap prior to entering the
condensate collection system. Failing to incorporate an air-gap may cause backpressure
on SAM-e and result in poor performance.
6 Some humidifiers allow distributor condensate to be returned to the unit. Refer to
humidifier manual for details.
7 For systems using condensate pumps, a P-trap and air-gap are still required at SAM-e
outlet. Never connect SAM-e directly to a pressurized drain line.

MAIN RULES FOR ATMOSPHERIC STEAM LINES:

Steam lines must be sloped
Condensate must be trapped (Use full-size ‘T’ for traps)
Steam lines must not have any restrictions that could cause back-pressure

Insulation
Factory-Installed Insulation
1 Unpack tubes and headers. Inspect tubes to ensure that stainless insulation covers have not
shifted during shipping. Tube covers should not be obstructing nozzles, and should be aligned
with nozzles. Header covers should be aligned with grommets, and not obstructing tube holes.
Cut around drilled holes to create access port in side of duct. This port should be large enough
to accommodate Mini SAM-e.
2 After tubes and headers have been inspected, install tubes and header according to this chapter.
Insert all steam tubes into header such that flanges are flush with rubber gaskets. Rotate steam
tubes, as needed, to ensure all nozzles are perpendicular to airflow. Do not lift manifold by steam
tubes.
Field Retrofit of Insulation
1 Unpack insulation covers. Inspect insulating covers for shipping damage; covers should be
straight and all foam strips should be aligned with edge of covers and. After tubes and headers
have been inspected, install tubes and headers according to this chapter. Insert steam tubes
into header, until flanges are flush with rubber gaskets. Rotate steam tubes, as needed, to
ensure all nozzles are perpendicular to airflow. Do not lift manifold by steam tubes.
2 Install tube insulation; each tube shall receive two (2) stainless steel covers and two (2) metal
straps for every four (4) feet of tube length. Fit insulating shields around distributor tubes,
ensuring edges of shields are aligned with nozzles. Secure tubes in place with metal clamps at
top and bottom. Take care to not over-tighten. See Figure 1.
NOTE: Multiple covers may be required to completely insulate SAM-e tube. Please refer to
Table: “Number of Insulating Covers Required to Cover a SAM-e Tube”.

Header Installation
1 Install header insulation for SAM-e; expand header insulation to fit over header and slide on.
Ensure that edges tuck underneath synthetic grommets on top of header. Secure insulation in
place using metal straps. See Step 2.
2 Install header insulation for SAM-e Dual Inlet; expand insulation to fit over header and slide on.
Additionally, expand smaller metal cover for inlet leg and slide on. If inlet leg insulation conflicts
with inlet adapter, trim insulation to fit. Secure both covers in place with metal strapping. See
Step 3.
3 Install header insulation for Mini SAM-e; expand header insulation to fit over header and slide on.
Take care when installing to avoid permanently bending insulation. Inspect for a tight fit after

Troubleshooting
Steam tubes discharge water:
1 Steam supply pipe is not insulated.
2 Steam supply pipe not properly drained or sloped.
3 Manifold or adapter condensate drain is clogged or malfunctioning.
4 Excessive back-pressure in condensate drain pipe (due to pressure in secondary condensate
drain); must be piped to non-pressurized condensate return.
5 Primary and secondary condensate drains are both joined together.
6 Condensate line has been routed too high (causing static back pressure).
Maintenance
Inspect SAM-e at start-up.
1 For humidifier maintenance schedule, refer to Installation, Operation, and Maintenance
