HM750A1000
ADVANCED ELECTRODE STEAM HUMIDIFIER
INTRODUCTION
The HM750 is the most advanced residential steam
humidifier available and provides steady and reliable
humidification for a home. The humidifier is designed for
connection directly to a supply air duct for humidity on
demand. The humidifier may be directly mounted to the air
duct, or remotely from the air duct, with a steam hose
connecting the humidifier to a distributor nozzle installed
at the air duct.

Humidifier Configuration
The HM750 is configured at the factory to operate under
most conditions without the need to change its
configuration.
NOTE: Because the humidifier is factory configured for
optimal performance, Resideo strongly
discourages changes to the configuration of the
humidifier not described in these instructions.
Before Installation
1. Ensure that available voltage and phase
corresponds with humidifier voltage and phase as
indicated on humidifier’s specification label.
2. Ensure that the dedicated external fuse disconnect
is of sufficient size to handle the rated amps as
indicated on the specification label. Refer to local
codes.
3. Ensure sufficient clearances will be available as
described in the Location section on page 6.
4. If the humidifier will be wall mounted, ensure steam
lines can be routed to duct as described in the Steam
Line Instructions on page 7.

CAUTION
Servicing
Disconnect main power before any servicing.
• The plumbing and electrical compartments
contain high voltage components and wiring.
Access should be limited to authorized
personnel only.
• During and following operation of the
humidifier, the steam and components in
contact with the steam such as the steam lines,
steam distributors, and condensate lines can
become hot and can burn if touched.
• Resideo 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 Resideo.
• To maintain warranty, only Resideo approved
parts and cylinders may be used in the
operation of the product.
CAUTION
Electrical
All electrical work should be done according to
local and national electrical code.
Electrical connection to be performed by a licensed
electrician.
Unit recommended to be powered by a dedicated
GFCI circuit.
CAUTION
Plumbing
Plumbing to be performed by a licensed plumber.
Drain water from humidifier can be very hot. Drain
water to floor drain. Do not drain to public sink.
All plumbing work should be done according to
local plumbing code.
CAUTION
Installation
Do not mount on surfaces hotter than 176 ÂşF
(80 ÂşC).
Do not mount in area where freezing can occur.
Do not mount on vibrating surface.
Do not mount on floor.
The HM750 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.
Do not mount outdoors without protection against
rain, snow, condensation or equivalent.
CAUTION
Water quality
The HM750 requires a cold water connection from
your home's main water supply between 15-
100 PSIG. A throttle valve may be necessary, and
a water shut-off valve is recommended for
safety. Reverse Osmosis (RO) and Deionized
(DI) water must not be used. Water conductivity
is important to ensure the electrode humidifier
operates effectively. Resideo recommends
125-1200 ÎĽS/cm (microsiemens/cm).

Parts and Accessories
The following parts and accessories are available and may have been included with your HM750 humidifier. The cylinder
is the only item that will need periodic replacement to maintain proper humidifier operation.
Table 2. Parts and accessories.
How the Humidifier Works
The HM750 is an atmospheric steam generator that uses
heat generated by electrical current flowing between
submerged electrodes to generate steam. The HM750 is
designed for on-demand air humidification via a steam
distributor nozzle.
STEAM GENERATION
• Once the humidistat terminals and the air proving
terminals are closed (AP on the control board), the
humidifier closes the power relay and measures the
electrical current.
• If current is lower than full load amperage, after a brief
delay the water fill valve will be activated and water will
flow into the fill cup. Water from the fill cup flows into
the bottom of the cylinder through a hose connected to
the drain valve housing.
NOTE: The cylinder is gravity fed from the fill cup. If
backpressure from the steam line is too high it
will cause water to back up in the fill cup and flow
down the overflow line to the drain.
• As soon as the water in the cylinder comes in contact
with the energized electrodes, current flows through
the water. The resistance of the water to the electrical
current generates heat and in turn steam. The electrical
current (and steam output) increases as the level of
water increases, as more of the electrode becomes
submerged. The unit continues to fill until the current
reaches full load amperage, or the high water sensor
detects a high water level.
• The water level and current draw in the cylinder
decreases from evaporation (through steam
generation).
• If the high water sensor was activated before full load
amperage is achieved, the water will boil down until the
high water sensor is no longer activated. If full load
amperage was achieved, the water will boil down to a
predefined amperage.
• The HM750 repeats the fill and boil down cycle
repeatedly to provide a constant steam output.
• Over time, minerals in the water will adhere to the
cylinder electrodes. The humidifier will automatically
fill to a higher water level to maintain full capacity
during the life of the cylinder. Eventually, because of
scale formation, it will no longer be possible for the
humidifier to reach its full capacity. The HM750
software monitors this condition and, when detected,
will stop operating and the Cylinder LED will be
illuminated.
DRAINS
• As steam is produced, minerals are left behind,
increasing the conductivity of the water. The HM750
auto-adaptive cycle will monitor the water conductivity
and perform drains to maintain the water at optimal
conductivity for peak performance.
• The auto-adaptive cycle ensures cylinder life is
maximized. It does this by keeping the tightest control
and most efficient use of water during the entire
cylinder life.
STEAM DISTRIBUTION
Steam generated by the humidifier may be introduced into
the air in two different ways. The humidifier may be
mounted directly onto the duct, to allow the steam
distributor nozzle to enter into the supply air duct.
Alternatively, the humidifier may be located remotely from
the air supply duct. It may be connected to the distributor
nozzle at the duct using a steam hose.
STEAM LINE
The steam line between the cylinder steam outlet and the
distributor nozzle serves two purposes: it is used as a
conduit to transfer the atmospheric steam from the
humidifier to the distributor nozzle, as well as providing a
means to remove condensate. See “Steam Line
Instructions” on page 7 for information on selecting steam
lines.
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 must also be sloped so that
condensate does not collect in the lines and create a
restriction to steam flow. As shown in the Plumbing
section, steam lines should maintain a slope back to the
humidifier of, as a minimum, 4 in. (10 cm) RISE per 12 in.
(30 cm) of RUN.
