HM700A1000
ELECTRODE STEAM HUMIDIFIER
MOUNTING
Mounting Procedure
1. The HM700 humidifier is wall mounted using a key-
hole located on the back of the humidifier.
2. Use #8 x 2 in. (5 cm) screws mounted into 2x4
studs or better if there is drywall or other spacers.
Two screws are needed, one for hanging the unit
and one for securing it so it will not lift off the
keyhole.
3. Install the top screw so that 1/4 in. (6 mm) is
exposed. Raise the unit and place the screw head
through the keyhole.
4. Make sure the unit is level and then insert and
tighten the second screw through the bottom hole.
Tighten the top screw.
Mounting Requirements
Honeywell does not accept responsibility for installation
code violations.
1. Install as close as possible to the steam distributor.
2. Minimize the use of turn or bends in the steam line
as much as feasibly possible.
3. Mount on a suitable wall or vertical surface. Do not
sit the on the floor, where freezing can occur, or on
vibrating surfaces.
4. Allow clearances for plumbing and electrical con-
nections. Consult local and national codes prior to
final location and installation.
5. Install only in areas with ambient temperature
41-104 °F (5-40 °C), and relative humidity 5-95 %
(noncondensing).
6. When possible, mount the HM700 humidifier at a
height convenient for servicing.

PLUMBING
Water Supply Requirements
Honeywell does not accept responsibility for installation
code violations. All drain and fill line connections should
be installed in accordance with local plumbing codes by a
licensed plumber.
1. Use 1/2 in. OD copper or plastic supply lines within
4 feet of the humidifier.
2. Install water shut off valve and coupler to facilitate
servicing.
3. Do not use reverse osmosis or de-ionized water.
4. Flush supply lines with fresh clean water after
installing, prior to operating the humidifier.
5. Do not solder/braze copper lines while connected to
the humidifier or the fill solenoid can melt or deform.
6. Water conditions must meet the following criteria for
optimal operation, consult factory for water
conditions outside of this range.
a. Pressure: 30 to 100 PSIG
b. Conductivity: 150-1200 Microsiemens
c. Temperature: 34-68 °F/1-20 °C
d. Hardness 0-10 GPG and Silica 0-4 PPM
–OR–
Hardness 0-3 GPG and Silica 0-14 PPM
Drain Line Requirements
1. Use 7/8 in. copper. Do not use PVC.
2. Install an air gap within three feet of the humidifier.
A copper reducer from 2-1/2 to 7/8 in. is ideal. Do
not allow the drain hose to bottom out in the funnel
cup.
3. The drain line should not end in a sink used
frequently by personnel, or where plumbing codes
prohibit it. Route to a floor drain or equivalent for
safety reasons.
4. Ensure drain line is adequately sloped and sized to
provide free and easy draining.

ELECTRICAL
CAUTION
Wiring to be performed by a licensed electrician.
This unit must be installed on a GFI Circuit.
CAUTION
Equipment Damage Hazard
Failure to wire the humidifier in accordance with
the wiring instructions could cause permanent
damage. Such errors will void the warranty.
Install Requirements
Honeywell does not accept responsibility for installation
code violations.
1. All electrical connections to the humidifier are to be
done while the unit is switched off, and the external
disconnect is open.
2. Wiring should be done by a licensed electrician.
3. Install a labeled disconnect switch within view of the
humidifier.
Installation Steps
1. Unit requires a dedicated circuit with GFI protection.
Bring circuit to a disconnect near the device to pro-
tect from electrical shock when servicing.
2. Hard wire humidifier to disconnect according as
shown at right.
3. Install factory-supplied jumper between the P termi-
nal and the terminal that corresponds to supply volt-
age.
4. Remove green wire attached to case body and
drain valve (remove canister for access).
5. Clip ground wire as close to drain valve as possible
and remove excess.
Fig. 3. Primary power connection.
NOTES:
— Honeywell requires the use of a GFI circuit on this device to protect the homeowner from electrical shock.
— When installed correctly, the green wire should be removed from the drain valve. The green wire comes
pre-installed from the factory to protect the homeowner in case of an improper installation or when it is not
possible to retrofit a GFI circuit.
— Ensure that adequate power is available to carry full humidifier amp draw as indicated on the specification
label.
— Do not use neutral wire as a ground; connect a dedicated ground to ground termination.
— All wiring to be in accordance with national and local electrical codes.

STEAM DISTRIBUTION
Install Requirements
The following instructions must be followed for installation of steam lines for the HM700. Failure to use recommended
material and exceeding maximum recommended length in Table 1, or failure to follow any other steam line installation
instructions will result in improper operation and could void the warranty.
Table 1. Recommended Steam Line Material for HM700 Duct.
*The use of steam line other than copper, stainless steel tube or Honeywell supplied steam line will void the warranty
and may adversely affect the operation of the humidifier.
*When using copper or stainless steel tubing (other than the supplied tubing), insulation is recommended due to high
temperature safety as well as reduced condensate.
To return condensate for HM700, insert copper tube
(supplied with equipment) half way into the condensate
opening of the fill cup along with the spring clamp
(supplied with equipment).
Insert the condensate hose into the condensate return
hole at the top of the HM700, and over the copper tube.
Fasten in place with the spring clamp.
MAIN RULES FOR ATMOSPHERIC STEAM LINES
• Steam lines must not have any restrictions which could result in back pressure.
• Follow recommended materials, size and length, see tables.
• Install steam line in a vertical (upwards) fashion from the HM700 to the distribution nozzle.
• Insulate with 1.0 in. (2.5 cm) pipe insulation.
• Trap condensate (Use full size ‘T’ for Traps)
• Do not over tighten hose clamp at cylinder steam outlet. The maximum torque is 12 in-lbs.
• Support steam line so weight is not on cylinder.
• Condensate traps must be a minimum of 6 in. (15 cm) in height or duct static pressure +2 in. (5 cm), whichever is
greater.
• Trapping by P-trap or pigtail. Support line as necessary to ensure it remains free of kinks.
