ELECTRODE STEAM HUMIDIFIER
DISTRIBUTION KIT
CAUTION
Before Servicing
1. Disconnect main power source before
accessing internal compartments.
2. The plumbing and electrical compartments
contain high voltage components and
wiring. Access should be limited to licensed
HVAC professionals only.
3. During and following operation of the
humidifier, the steam components in
contact with the steam such as the cylinder,
steam lines, steam distributors, and
condensate lines can become hot and burn
if touched. Please consult HM700
Installation manual for reference.
4. Humidity equipment installed by
unqualified personnel or the use of parts
and components not supplied with the
humidifier or this kit will void warranty.
Steam Distributor
The HM700ADISTKIT is a remote mount, stainless
steel steam distribution kit used with the HM700
Electrode Steam Humidifier. The distributor is
installed in a ventilation duct to distribute the steam
produced by the HM700.
The HM700ADISTKIT consists of a steam distributor,
steam hose, condensate hose, and installation
hardware.
The steam distributor should be installed as close as
possible to the humidifier. Short steam distribution
lines minimize condensate loss and the possibility of
generating backpressure in the steam distribution
line.
STEAM DISTRIBUTION
Steam generated by the humidifier may be
introduced into the air in several different ways. The
most common method for adding the steam into the
air is to mount a steam distributor tube in a supply air
duct as shown in Fig. 2.
STEAM LINE
The steam line between the cylinder steam outlet and
the distributor serves two purposes: it is used as a
conduit to transfer the atmospheric steam from the
humidifier to the distributor, as well as providing a
means to remove condensate. See “Steam Lines and
Condensate Return Instructions” on page 2 for
information on selecting steam lines.
CONDENSATE RETURN
Whenever steam is distributed condensate is formed
in the distribution system. Insulating steam lines is
one important way to reduce the amount of
condensate formed. Steam lines are sloped so that
condensate does not collect in the lines and create a
restriction to steam flow. The condensate must be
collected and removed from the system so that it does
not build up and leak into the duct. Condensate can
be returned to the HM700 fill cup to reduce water
waste or can be fed to drain.
