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.

• Outside Temp 20° F /70% relative humidity

• 8 foot ceiling height

• Internal moisture gain of one pound per hour

• Furnace on-time of 70%

This chart uses A.R.I. standard designations:

A “Tight Home” is assumed to be well insulated with vapor barriers, tight storm windows and

doors, and a dampered fireplace. Air exchange rate of .50 changes per hour.

An “Average Home” is insulated and has a dampered fireplace, but there are no vapor barriers,

storm doors, or storm windows. Air exchange rate of 1.0 change per hour.

A “Loose Home” is generally one constructed before 1930, has little or no insulation, no storm

doors, storm windows, weather stripping or vapor barriers, and often no effective dampering of

fireplaces. Air exchange rate is as high as 1.5 changes per hour.

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.

Physical installation

Caution:

Only a trained HVAC servicer or contractor should install this

humidifier. Do not connect the unit to the power source until

installation is complete. A thorough checkout of the unit

installation should be completed before operation. Failure to

follow these directions may void the manufacturer’s original

warranty.

Remember to select a location that is readily accessible for

periodic inspection and cleaning of your humidifier. Allow a

minimum of 2” clearance in front of the humidifier and 2”

below the water pan to allow for maintenance and repair.

Prior to installing this product:

• Read the instructions carefully to ensure safe operation.

Failure to follow them could damage the product or cause

a hazardous condition.

• Check the ratings given on the product to make sure it is

suitable for your application.

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).

Mounting behind a wall using discharge

extension (707U only)

1. Locate the inside wall template and mount on

inside wall. The inside wall opening must be cut

first. Be sure to follow the limitations noted as A,

B, and C printed on the template.

2. Check the template with a level to ensure proper

installation of the humidifier.

3. Drill (6) 5/16” diameter holes through the inside

wall only as shown on the template for mounting

the wire bracket on the wall using the anchor bolts

and flat washers provided. Drill a saw access hole

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

water reservoir pan, be sure that the drip tubes do

not interfere with the operation of the float and

valve assembly. Interference can be eliminated by

rotating the entire atomizing assembly within the

water reservoir pan.

11. Before mounting the humidifier in its final position, carefully rotate the impeller assembly

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.
