The location of the humidifier depends largely on the steam distribution system. The required minimum clearances are shown on the
right. The table below shows the required minimum clearances for
a Nortec EL Space humidifier.
When choosing the location of the humidifier, install it as close as
possible to the steam distributor to minimize heat loss through the
steam line.
When possible, install the humidifier below the steam distributor.
Make sure that the selected location permits proper routing of steam
and condensate lines.
Allow adequate clearances around the humidifier for ease of maintenance. Although the Nortec EL humidifier requires no side clearance,
Condair recommends minimum clearances of 6 in (150 mm) on the
sides. A clearance of 24 in (610 mm) between the humidifier and
the ground is required. Observe all local and national installation
codes. Condair is not responsible for any installation code violations.
Do not mount the humidifier on hot surfaces, or surfaces that can
freeze, or near vibrating components, or on the floor. In addition,
the mounting surface must be able to withstand temperatures of
140-158°F (60-70°C) that can be generated during operation of
the humidifier.
The humidifier should be mounted on a wall or other suitable surface
that offers a sufficiently high load-bearing capacity.
The Nortec EL humidifier should be installed in a drip-proof location
within buildings, where the ambient temperature is 41-104°F (5-40°C)
and the relative humidity is 5-95% (non-condensing).

Use steam line made of copper or stainless steel tube exclusively,
or use a Condair steam hose for short distances. Steam line made
of any other material may adversely affect the operation of the
humidifier, and will void the warranty. Refer to the table below for
steam line sizing.
To prevent excessive backpressure in the steam cylinder, the steam
line must not have any restrictions.
The steam line must run straight up from the humidifier minimum
12 in (300 mm) before any bends.
The steam line must have a constant slope – minimum upslope of
10°, or minimum downslope of 2°.
Do not merge steam lines, except at the steam distributor. Use a
Condair adaptor designed for the purpose.
Insulate the steam line with minimum 1 in (25 mm) pipe insulation.
Support the steam line so there is no load on the humidifier.

All water supply and drain connections must be installed to local
plumbing codes.
The water supply line should be minimum 1/2 in (12.7 mm) in
diameter, with a shutoff valve and a union fitting.
The water supply to the humidifier must be cold potable drinking
water (and not RO or DI water). The conductivity of the water should
be 150-1200 micro-seimens/cm (hardness 0-12 gpg, when Silica
is between 0-4 ppm, 0-3 gpg when Silica is between 4-14 ppm;
Silica content above 14 ppm is not recommended). pH should be
between 7 and 7.5.
The water supply should be filtered to 5 μm (optional, but recommended), surge-free and pressure regulated to 30-80 psig (207-550 kPa).
Water temperature should be 34-104°F (1-40°C).
The air gap funnel should be located away from the control cabinet
to keep any rising steam from damaging the electrical components
in the cabinet. The drain piping should have a minimum internal
diameter of 7/8 in (22 mm).
The flexible bent hose exiting the humidifier should be connected
to a drain line with a minimum internal diameter of 7/8 in (22 mm)
and secured with clamps.

All wiring must only be done by a licensed electrician in accordance
with the wiring diagram (refer to the Installation Manual), and local
and national codes.
An external dedicated fused disconnect switch must be installed
close to the unit to allow for power interruption during servicing and/
or maintenance. The fusing must not exceed the maximum circuit
protection shown on the specification label. The optional internal
fusing is not a substitute for an external disconnect switch.
The humidifier should only be connected to primary power (main
power) after all installation work has been completed.
All cables must enter the control cabinet in the humidifier through
appropriate cable glands or grommets, and must be properly secured
to prevent fraying, or become a tripping hazard.
DANGER!
Risk of electric shock! The Condair humidifier is mains powered,
and should only be wired by a licensed electrician.
CAUTION!
Risk of damage to electronic components in the control cabinet
due to ESD (electrostatic discharge). Refer to ANSI/ESD-S20.20
for appropriate measures to prevent damage to electronic

If a blower pack is installed, then connect it to terminal points “8”
and “9” on the low voltage terminal strip. Make sure that no other
wires are connected to these terminal points. If using multiple blower
packs, make sure that they are connected in series. Install a jumper
between terminal points “8” and “9” if a blower pack is not used.
Connect external monitoring devices (for example, high limit humidistat, air proving switch, etc.) in series to terminal points “1” and “2”
on the low voltage terminal strip. Install a jumper between terminal
points “1” and “2” if external monitoring devices are not used (not
recommended).
Connect an external humidity sensor input or direct demand
modulating input to terminal points “3” and “4” on the low voltage
terminal strip. Do not connect multiple modulating signals to the
same modulating input on the humidifier. If necessary, a second
modulating signal can be connected to terminal point “5” and “3”,
using terminal point “3” as common. Note: If the cable shielding is
already connected to a potential or a grounded conductor, do not
connect it to terminal point “3”.
4.
5.
If a 24 V On/Off humidistat is used, connect the input to the terminal
points “4” and “6” on the low voltage terminal strip. When connecting
a 24 V On/Off humidistat, set the jumper JP1 on the driver board to
24 V (so that terminal point “6” will output 24 VDC).
If an external On/Off input is used to control the humidifier, connect
it to connector X11 on the driver board.
CAUTION!
Risk of damage to internal component. DO NOT apply voltage
to low voltage terminal strip terminal points “1” and “2” through the
contacts of the external On/Off devices.
