Dear Owner:
Congratulations on your choice of a Herrmidifier brand humidification system. Your family can
now look forward to breathing more comfortable air, winter after winter. We are committed to
providing advanced products that improve the quality of the air you breathe.
The following information will familiarize you with the operation of your new humidifier and
provide helpful tips on how to obtain maximum performance from your unit.
Introduction
The benefits of a properly humidified environment (35-50% Relative Humidity) are many. They
include both personal comfort as well as the preservation of furniture, draperies, carpets,
wooden floors and cabinets, paintings, pianos, etc.. Your home will be more comfortable at a
lower temperature (i.e.: 68° F) at 30-40% Relative Humidity (RH) than at 71° to 72° F without
controlled humidity. Since every degree of temperature setback represents about 3% of your
heating costs, this can possibly represent a significant annual savings.
During the heating season, cold air is brought into the home and heated. When heated, this air
dries out and greatly increases its capacity to hold more moisture. By using a humidifier, a source
of water is provided to satisfy this increased moisture holding capability, rather than having it
drawn from our body surface and the surrounding furnishings in the home.
A properly maintained and efficiently operating humidifier is a source of improved Indoor Air
Quality and personal comfort. We hope you will enjoy the benefits of your humidifier.

Capacity Selection Guide
Operation
Your centrifugal atomizer type humidifier operates on the principle of breaking down water
droplets into a fine mist and atomizing the moisture into the air.
If applicable, set the humidistat in the recommended range of 30-40% relative humidity for
automatic humidity control during the heating season (a lower setting may be used to control
condensation on single pane windows). During the first heating season, check the mineral
buildup in the humidifier every month to establish the proper cleaning schedule. Clean the unit
at the end of each heating season, or whenever mineral deposits appear to be impeding the
discharge of the water mist.
When shutting the humidifier down for the summer months, start with cleaning any mineral
accumulation from the unit. Leave the water turned off and the unit dry. If the furnace fan is
to be used for cooling purposes, disconnect power to the humidifier or turn the humidistat to
the OFF position.

Selecting a location for the unit
Mounting on face of vertical return duct or side of
horizontal return duct
When mounting your humidifier on the face of a horizontal
return duct, or on the face of a vertical return duct, certain
conditions must be met for its proper operation:
• Mount the humidifier on the vertical or horizontal cold air
return duct.
• Locate the humidifier at least four (4) linear feet upstream of
either the furnace fan and /or filter and any turn in the duct.
This will ensure that condensation does not collect within the
duct and cause oxidation (rust).
• Mount the humidifier at least six (6) linear feet (preferably 10
feet) upstream from any electronic air cleaner. Failure to
follow this recommendation can cause excessive nuisance
arcing and or power supply failure.
• If the duct seams inside the duct are not flat, locate the
humidifier at least three (3) linear feet upstream from the
seam.
• If the humidification needs of the home require more than
one humidifier, each unit should be installed a minimum of (3)
linear feet apart.
• DO NOT use this humidifier on the discharge or warm air
supply side of a forced air heating system. This will reduce the
efficiency of the humidifier and may cause operational
problems.
• DO NOT mount the humidifier in a furnace jacket.
• DO NOT install the humidifier where freezing conditions could
occur.
• DO NOT install on gravity hot air systems.

Selecting a location for the unit
Mounting behind a wall using the discharge extension (707U only)
When selecting a location for the installation of your humidifier as a free standing unit, certain
conditions must be met for its proper operation:
Locate the humidifier in a convenient spot where the working part of the humidifier can be
hidden (i.e. closet, stairway, garage, utility room, etc.)
When deciding on the location of the humidifier, please keep in mind the following points:
• The discharge nozzle should be at least two (2) feet below the ceiling and from a vertical wall
along the side.
• The discharge nozzle should be about six and a half (6 1/2) feet from the floor. If this is not
possible, locate the humidifier in the area of least traffic.
• The humidifier should be located between wall studs to facilitate cutting the discharge hole
through the wall.
• No obstructions should be directly in the path of the discharge mist for six (6) feet. This
includes, but is not limited to ceiling lights, light cords and ceiling fans.
• DO NOT install the humidifier where freezing conditions could occur.

Mounting on the face of a vertical return duct
or side of a horizontal return
1. Mount the installation template on the side of the
cold air return air duct with the center line of the
template lined up with the center line of the return
air duct. The narrow side of the duct may be used if
space permits.
2. Check the template with a level to ensure proper
installation of the humidifier.
3. Drill (4) 1/8” diameter holes (as shown on the
template) for mounting the wire bracket with sheet
metal screws and flat washers provided.
4. Cut out the circle marked on the template. Do not cut
this opening undersized.
5. With a hammer and a heavy piece of metal,
straighten the metal edges to prevent injury to
yourself and damage to the humidifier.
6. Fit the rubber channel around the cut-out to cover
the rough edges of the hole and trim to fit.
7. Attach the wire mounting bracket to the duct with (4)
#10 sheet metal screws and flat washers (provided).
8. Move the side adjusting arms vertically until the shelf
of the wire mounting bracket is level.
9. Mark the duct for securing adjusting arms and drill (2)
1/8” holes. Fasten the arms in this position with (2)
#10 sheet metal screws and flat washers (provided).
10. The float and valve assembly have been factory
adjusted to maintain 1-1 1/2” of water in the water
reservoir pan at normal water pressure. If necessary,
bend the float arm to the required position to
maintain the water level at other water pressures.
11. Before mounting the humidifier in its final position,
carefully rotate the impeller assembly by hand to
ensure it rotates freely. Position the humidifier on the
wire mounting bracket with the float and valve
assembly connection facing the most convenient
location. Be sure that the water reservoir pan feet do
not rest on the wire bracket and that the water
reservoir pan is level.
12. The discharge dome should approach the opening in
the duct, however, it should not extend into the duct.
There will be no heat loss, due to the negative
pressure of the cold air return duct (the air flow will
create a vacuum in the duct).

through the inside wall only in Area I as shown on
the template.
4. Cut out Area I of the inside wall using a saber saw
or equivalent. Do NOT cut out Area II at this time.
Do NOT cut through the entire wall as the
discharge hole on the other side of the wall will be
higher up.
5. Measure the thickness of the wall studs using the
cutout portion (Area I) on the template. This
measurement is used to drill a pilot hole for
locating the hole in the outside wall.
6. Drill (1) 1/4” pilot hole through the inside and
outside wall at the proper point in Area II on the
template. This will mark the proper center for the
discharge hole on the outside of the wall.
7. Cut out Area II of the inside wall using a saber saw
or equivalent. Do NOT cut through the entire wall.
8. Remove the template from the wall. In the (6)
5/16” diameter holes previously drilled into the
inside wall, install the (6) anchor bolts provided.
Remove each one of the bolts, and mount the wire
mounting bracket to the wall with (6) removed
bolts and flat washers.
9. The float and valve assembly have been factory
adjusted to maintain 1-1 1/2” of water in the water
reservoir pan at normal water pressure. If
necessary, bend the float arm to the required
position to maintain the water level at other water
pressures.
10. When installing the atomizing assembly into the

by hand to ensure it rotates freely. Mount the humidifier on the wire mounting bracket with
the float and valve assembly connection facing the most convenient location, but providing
the least obstruction to traffic. Be sure that the water reservoir pan feet do not rest on the
wire bracket and that the water reservoir pan is level.
12. Locate the discharge hole on the outside wall. Mount the outside wall hole template using
the center of the pilot hole for reference. A pencil may also be used to find the previously
drilled pilot hole. When the outside wall hole template is secured, cut the hole in the
outside wall, using a saber saw or equivalent, for the discharge nozzle.
13. Measure the total thickness of the wall, not the stud thickness, but the distance between
the surfaces of the inside and outside walls.
14. The length of the discharge extension nozzle (provided) will be 2 5/8” long PLUS the total
wall thickness as determined in the previous step. Cut the extension nozzle to length on the
square end. The opposite end of the extension nozzle is angled to provide the correct fit
with the outside wall.
15. Fit the flexible connector sleeve onto the discharge dome and fasten securely with one (1)
hose clamp provided.
16. Insert the angle cut end of the extension discharge nozzle into the hole cut into the inside
wall, making sure the white line is pointed UP. Connect the extension discharge nozzle to
the discharge dome’s flexible connector sleeve. The angle cut end of the extension discharge
nozzle should be adjusted so that 5/8” of the tube extends past the outside wall. Secure in
position with one (1) hose clamp.
17. Install the cosmetic bezel onto the discharge side of the extension discharge nozzle. Making
sure that the bezel sits flat against the wall, 1/4” of the extension discharge nozzle should
extend past the bezel. This setup is necessary to prevent excessive condensation.

Final installation steps for all mounting locations
• Install the saddle valve on the nearest cold water supply
pipe (see the instructions on the package). If applicable,
connect the saddle valve upstream of any type of water
softener.
• After the saddle valve has been installed and 1/4” copper
tubing fitted to the valve, but before attaching the copper
tubing to the float and valve assembly, turn the saddle valve
to the open position and discharge the water into a bucket
or pan. This will allow the water to void the line of any
debris that may have accumulated during the installation
process.
• Attach the 1/4” copper tubing to the float and valve
assembly with the ferrule and compression nut (provided).
Caution: The float and valve assembly must not turn when
tightening the copper tubing compression fittings to the
humidifier water reservoir pan fitting.
• Turn the water supply on at the saddle valve.
• Check the water level in the water reservoir pan to ensure
it is 1-1 1/2” deep.
IMPORTANT:
In installations where accidental overflow could cause water
damage, connect a drain hose from the humidifier water
reservoir pan overflow tube to a drain. Do NOT use a soldered
joint because the overflow tube will become heated and warp
the water reservoir pan.

Electrical installation
This humidifier is intended to be wired directly to the integrated
control panel on your furnace. The electrical tap will provide
power to the humidifier whenever the circulating air blower is in
operation.
Read the instructions in the furnace installation manual carefully
before attempting installation or operation of this humidifier.
Failure to follow these instructions may result in improper
installation and therefore, void the manufacturer’s warranty.
1. Remove the cover from the junction box in the furnace jacket.
2. Connect the humidifier input leads to the two (2) leads that
run to the furnace blower motor. This connection provides for
the automatic operation of the humidifier during the heating
season.
3. The humidifier will only operate when the furnace blower is
in operation.
4. It is recommended to install a humidistat (provided with
model 707U) in the system to provide optimum performance
when continuous air circulation is desired.
5. If a humidistat is not used in the installation, install an ON/OFF
switch in its place. This provides a simple, yet effective,
method of turning the humidifier off during the summer
months when humidification is not desired.

Maintenance
To enjoy the benefits of a properly humidified environment,
periodic cleaning is necessary to control both water and
household impurities. Film or scum, which can contain bacteria
or fungi, may appear on the water surface, the sides, or bottom
of your humidifier. A crusty deposit or scale may also appear
and is composed of minerals that have settled out of the water.
To improve the efficiency of your humidifier, and to reduce the
possibility of a health hazard, it is recommended that you take
the following precautions:
• Follow the manufacturer’s recommended cleaning and
maintenance instructions below and on the next page.
• The amount of minerals and other impurities in a water
source can vary greatly, therefore, the frequency of
cleaning the unit also varies.
• During the heating season, check for film or scale build-up
in the unit, or any moving part. Establish a proper cleaning
schedule to ensure the efficiency of the humidifier.
• An algaecide, such as a humidifier cleaning tablet or
bacteriostatic liquid/powder, can be used to combat algae
build-up, should it become evident.
• At the end of the winter humidification season, drain and
thoroughly clean your humidifier as part of the summer
shutdown.
Like your heating system and air conditioning unit, periodic
maintenance and cleaning are required to ensure the safe and
efficient operation of your humidifier. Due to the operation
cycle of the furnace and humidifier, it may require 2 to 5 days
to reach the proper humidification level.
CAUTION
Before cleaning or
servicing this unit, it is
recommended that
the unit be
disconnected from
any electrical supply
outlet.

Maintenance instructions for models mounted on the face of a vertical return
duct, side of a horizontal return duct, or mounted behind a wall using
discharge extension
Your humidifier is constructed from quality materials to assure superior
performance during normal operation. The motor bearings are permanently
lubricated and do not require oiling. The motor is also thermal overload
protected against extreme conditions.
To clean the unit:
1. Turn the power to the furnace OFF or turn off the electric switch to the
humidifier, if provided.
2. Disconnect the humidifier motor leads.
3. Turn off the humidifier water supply from the saddle valve and remove
water line from humidifier.
4. Remove the humidifier from the wire mounting bracket.
5. Remove the discharge dome from the humidifier by pressing on the sides
of the dome and lifting upward.
6. Lift the entire atomizing assembly from the water reservoir pan.
7. Remove the pump from the end of the impeller shaft. If the pump is stuck
in the motor drive shaft, run hot water over the end of the shaft for a
few seconds to loosen the pump.
8. Flush water through the impeller tube, ensuring that the six holes at the
top of the impeller tube are open and clear of mineral deposits. A pipe
cleaner works well for this cleaning operation.
Note: The impeller tube and pump can become clogged by algae
formations prevalent in certain water sources. The addition of 10 drops
of bleach to the water reservoir pan each week is advisable.
9. Replace the pump into the impeller shaft.
10. Carefully rotate the impeller to ensure it turns freely. Do not force the
impeller shaft to turn or breakage could result.
11. With the atomizing assembly removed, clean the water reservoir pan
thoroughly. We suggest either a water/white vinegar solution or liquid
humidifier cleaner.
12. Reassemble and remount the humidifier by reversing steps 6, 5, and 4.
13. Reconnect the water line and motor leads to the humidifier, turn on the
water supply from the saddle valve and restore electrical power.
