Mounting
Mount either oor mounted or on a mounting stand (stand
optional). Nortec SE 50 models can also be ceiling mounted
with the optional ceiling installation kit, part number 2520345.
1. Install on a level platform in an area with ambient temperature
41-104 °F (5 – 40 °C) relative humidity 5-95% (non-condensing).
2. Ensure mounting surface is strong enough to support the full
weight of the humidier and accessories. If mounting on the
optional stand, assemble stand according to the instructions
provided with the stand and secure stand to the oor via the
holes in the leg support plates following any local codes or
regulations.
3. Install in location where the electrical power, boiler steam, and
drain lines can be connected.
4. Locate the humidier as close as possible to the steam
distributor location, net output will be reduced as a result of
heat loss through the steam line.
5. Condensate drain is located close to the bottom of the
humidier. Locate the unit so that condensate lines slopes
down to boiler or use pump (by others) to lift to boiler. Use
stand if necessary.
6. Avoid mounting humidier on combustible surfaces including
(but not limited to) carpet, tile, or certain insulating materials.
7. Clearance dimensions shown are for reference only and are
the minimum required for maintenance of the humidier.
Consult local and national codes before nal location and
installation.
8. location. Net output will be reduced as a result of heat loss
through the steam line.

Plumbing
Water Supply
1. All water supply and drain line connections must be installed
in accordance with local plumbing codes. Condair accepts no
liability for installation code violations.
2. Install water shut o valve and union before humidier to
facilitate servicing.
3. Supply water requirements:
30 - 80 PSIG
Hardness 5-7 gpg
Chlorides 0-25 ppm
Alkalinity 7.5-8.5 pH
Drain Line(s)
1. Drain line should be a minimum of 1.25” OD copper,
sloped away to allow proper drainage.
2. Drain line must have an air gap installed within three feet
of the drain outlet.
3. Auxiliary drain connection with manual shut o valve
is recommended for all units. Valve to be left closed on
units without freeze protection option installed.
4. Drain Water is very hot, do not use plastic pipe for drain
or condensate lines, do not drain to public sink. Route to
oor drain or equivalent.

Install Requirements
1. Boiler steam supply line design is the responsibility of the
installer. Condair does not accept liability for installation
code violations.
2. The Nortec SE will operate on supply steam pressures
between 5 and 15 psi measured at the globe valve. Pressure
exceeding 20 psi will damage the humidier. If connecting
via pressure reducing valve, install a safety relief valve to
prevent pressures in excess of 15 psi.
3. Boiler steam supply line must be designed so that that
design pressure is present at the globe valve when the
globe valve is completely open (100% demand).
4. Condair supplies a globe valve, actuator and wye strainer
with each Nortec SE humidier.
5. Humidier condensate drain should be returned to the
boiler and not mixed with water from the humidier tank or
auxiliary drains.
6. The steam supply pressure can be entered into the
Nortec SETC control software in the ‘Control Settings’ menu
to provide an accurate display of unit output. Pressure

Operations manual.

Actuator Mounting
1. Install Jam nut and lock washer on globe valve stem.
2. Thread the stem extension onto the globe valve.
3. Mount the actuator to the globe valve and secure to the
valve with the mounting nut.
4. Extend the valve stem, fully closing the globe valve.
5. Load the actuator with the provided allen key, two full
turns clockwise.
6. Thread the stem extension until the extension pin hole
aligns to the actuator pin hole and secure with the
connecting pin.
7. Tighten the jam nut against the stem extension.
8. Ensure the valve completely closes when the actuator is not
powered.

Install Requirements
1. Use ONLY copper, stainless steel tube, or Condair supplied steam
line for the atmospheric steam distribution line.
2. Follow recommended steam line materials, size, and length. See
tables to right.
3. Slope the steam lines, minimum 2” for every horizontal foot
against the ow of steam, ½” for every horizontal foot with the
ow of steam.
4. The rst vertical 12” of steam line o the top of the humidier
must not have any bends or turns.
5. Insulate copper or steel tube steam lines with 1.0 in. (2.5 cm) pipe
insulation.
6. Steam lines must not have any restrictions or condensate
trapping which could cause back pressure.
