TABLE 1 – Operation Guide
Models EHUMD300ABA00B and EHUMD500APA00C with Automatic
Humidifier Control: (for Manual Humidifier Control – see page 5)
Your Automatic Humidifier Control is installed in the cold air return. During
the first heating season, your Automatic Humidifier Control needs to be
set initially to match your home’s condition. Please follow these steps
when adjusting your Control (refer to Figure A).
1. Turn the dial setting knob to “5,” which is within the normal range.
During the next 24-48 hours it may be necessary to adjust the dial for
more or less humidity, depending on your personal comfort and home’s
requirements. Refer to the “Operation Guide” (Table 1).
2. During the coldest portion of the first heating season, minor
adjustments may be necessary. This is dependent upon your individual
home construction, refer to the “Operation Guide” (Table 1).
Condition Solution
Condensation on windows Reduce the setting on the control dial
by 1 increment.
Lack of humidity Increase the setting on the control dial
by 1 increment.
Humidifier does not operate Turn dial to “Test.” Make certain furnace
and blower are operating. If humidifier
still doesn’t operate, consult your air
conditioning and heating dealer.
Humidifier won’t shut off Turn dial to “Off.” If humidifier continues
to operate, consult your air conditioning
and heating dealer.
Test mode System operation is checked by setting
the knob to “Test.” Make certain furnace
and blower are operating. Humidifier will
operate for one minute.
The relative humidity in your home
will now be accurately controlled
to meet your needs and should not
need further adjustment during
future heating seasons. Make note
of the dial setting in the event you
temporarily move the knob when
performing annual maintenance of
the Humidifier.
II. OPERATING INSTRUCTIONS
FIGURE A
Your new humidifier has been installed to operate in conjunction with your
furnace. When the Humidifier Control calls for humidity and the furnace
blower is operating, water flows to the distribution tray located at the
top of the humidifier. The water is evenly distributed across the width of
the tray and over the Humidifier Pad. Dry, hot air is moved through this
moisture laden Humidifier Pad where it is evaporated into a vapor. This
humidified air is circulated throughout your home. Humidified air helps to
reduce static electricity, prevents wood furniture from drying out, helps
prevent nasal passages from becoming too dry and makes your home more
comfortable.
Important Notes About Your Humidifier:
When the humidifier is operating, there will be a small, steady stream of
water to drain. Do not use the saddle valve to regulate the water flow. The
saddle valve is designed to be either completely open or completely closed.
Although your humidifier incorporates a self-flushing action, the Humidifier
Pad will develop mineral build-up over time. To assure high capacity,
trouble-free performance the Humidifier Pad should be replaced
annually.
For water distribution trays with a synthetic fabric liner: The
synthetic fabric liner provides an even water flow over the Humidifier Pad.
It is normal for some mineral deposits to form in the distribution tray as it
dries out between humidification cycles. These deposits can actually help
distribute water in the tray, but if they form enough to block the openings,
they should be removed as described in the “Periodic Preventative
Maintenance” section of this manual.
For water distribution trays with a granular coating: The coating on
the bottom of the distribution tray provides an even flow of water over the
Humidifier Pad. Do not clean the mineral scale off the bottom of the
distribution tray at the end of the humidification season. The scale
actually provides an excellent track for the water to follow.
I. PRINCIPLE OF OPERATION
90-1054

- 4 - - 5 -
To check the humidifier’s operation, note the Control setting and set the
Automatic Humidifier Control to the test mode when the furnace blower
motor is operating. Water will flow into the humidifier for 1 minute and
then it will turn off. This insures the humidifier is operating properly. Do
not leave the Control in the test mode as it will not operate. Reset the
Control to it’s original setting.
TABLE 3 – Outdoor-Indoor Relative Humidity
Model EHUMD200ABM00B with Manual Humidifier Control
or Model EHUMD300ABA00B and EHUMD500APA00C with
Automatic Humidifier Control in Manual Mode:
(for Automatic Humidifier Control – see page 3)
The Manual Humidifier Control is installed either in the living area (typically
near the thermostat) or in the cold air return. The Automatic Humidifier
Control (in the Manual Mode) is installed in the cold air return. It is
important to anticipate a drop in outdoor temperature and reduce the setting
accordingly to avoid excessive condensation. For example, with an outdoor
temperature of 20°F the recommended setting will be 35% relative humidity.
If the temperature is expected to fall to 0°F that evening, then merely reduce
the setting to 25% several hours prior to the temperature change.
The recommended settings on the Humidifier Control are based on years
of research (see Table 3) and experience as to what is best for the average
home. These settings represent a compromise between RH levels that would
be most desirable for comfort reasons and humidity levels that are suitable
for protection of your home. For example, a wintertime indoor RH of 50%
may be considered ideal by some, but unfortunately, it probably would result
in damage to your home. Observance of the recommended RH levels on
your Humidifier Control, therefore, is an important safeguard. Condensation
of water on inside windows in the form of fogging or frost is usually an
indication of too high relative humidities. This same condensation can take
place in other areas in your home with the possibility of damage resulting.
Outside Temperature Recommended RH
+40°F 45%
+30°F 40%
+20°F 35%
+10°F 30%
0°F 25%
–10°F 20%
–20°F 15%
The Humidifier Control is a precision instrument that can be used to
determine the RH accurately in your home during the winter. Turn the dial
to the lower setting, then reverse the dial direction slowly until a “click” is
heard. At this point, read the RH on the dial. This will be very close to the
actual RH in your home.
Your Automatic Humidifier, is a high precision system that will accurately
maintain the relative humidity in your home. For every 1°F change in
outdoor temperature, the Control will automatically adjust the indoor
relative humidity (RH) by 1/2%. If you would like to determine the RH in
your home, follow these steps:
1. Determine the outdoor temperature.
2. Activate the furnace blower by setting your thermostat fan switch to the
“On” position, or setting your thermostat to a higher temperature.
3. Turn the Humidifier Control dial setting to the “Off” position. Then, slowly
turn the dial clockwise until you hear the solenoid valve “click on.” Next,
slowly turn the dial counter clockwise until you hear the solenoid valve
“click off.” At this point, make note of the dial setting.
4. Locate your dial setting on Table 2. Follow the dial setting to the right
until it intersects with the current outdoor temperature. This is the
relative humidity in your home under existing conditions.
5. Return the thermostat and the Humidifier Control to their original
settings.
The Automatic Humidifier will accurately control the humidity in your
home to a maximum of 45% RH and a minimum of 10% RH. The values of
outdoor temperature and dial settings may fall in between or outside of
the listed values in Table 2. In these cases, you can only approximate your
home’s actual indoor RH.
As an example, if the outdoor temperature is 20°F, and, following step 3,
the humidifier turns off at “5” on the dial range, then the RH in your home is 35%.

IV. ANNUAL MAINTENANCE
V. ANNUAL SUMMER SHUTDOWN
For best performance, we recommend that you replace the
Humidifier Pad in your Humidifier annually.
To obtain a replacement:
• Call your heating and air conditioning dealer.
• Look in the Yellow Pages under Heating & Air Conditioning Contractors.
• If none of the above are successful and you still need information,
please feel free to write us or send an email to our website.
For Models EHUMD200ABM00B, EHUMD300ABA00B
close the bypass damper.
AUTOMATIC HUMIDIFIER CONTROL:
Humidifiers controlled by the Automatic Humidifier Control require no
control adjustment. Shut off the water supply to the humidifier by closing
the saddle valve.
MANUAL HUMIDIFIER CONTROL:
For humidifiers controlled by a Manual Humidifier Control, simply turn the
Control to the “Off” position. Shut off the water supply to the humidifier
by closing the saddle valve.
III . EFFECT OF WATER CHARACTERISTICS
To check the humidifier operation, set the Humidifier Control above the
click point, make sure that the water saddle valve is open and that there is
electricity to the humidifier. Generally, the furnace and blower motor must
be operating for the Humidifier Control to function. After the humidifier has
operated for several minutes and water is entering the humidifier and coming
out at the drain, reduce the Humidifier Control setting below the click point
and the humidifier should automatically shut off. Now set the Humidifier
Control dial at the recommended inside relative humidity, depending on the
outside temperature. Follow the suggested settings prior to a drop in the
outside temperature.
Additional Information
Be sure to keep fireplace dampers closed when not in use. They provide
an excellent escape route for heat, as well as humidity. Humidity is lost
at an even faster rate than heat because water vapor tends to seek its
own level and your humidifier would not be able to replace it even when
running at full capacity.
On occasion, indoor moisture producing activities such as clothes drying,
cooking, showers, etc., may raise the relative humidity level higher
than it should be, even though the Humidifier is not operating. Telltale
indications, again, are condensation or frost on cold surfaces such as
windows, doors, walls, etc. If such condensation persists for several hours,
your home should be ventilated to dissipate the potentially damaging
excess moisture.
Your humidifier will operate effectively using either hot, cold, hard or
mechanically softened water. Whether to use available tap water, even
though it may be quite hard, or chemically softened water, is a common
concern to homeowners when installing a humidifier. Because of the
humidifier’s design, most of these solids are effectively controlled by
flushing them down the drain.
Water used in homes contains varying amounts of minerals. The residue
remaining as a result of hard water evaporation is primarily calcium and
magnesium components and is usually quite hard, scaly, and dense.
Residue from softened water tends to be soft and fluffy and has a greater
volume than hard water residue. The service life of a Humidifier Pad
may be extended by using hard water, but in either case, the Humidifier
Pad should be changed once a year. This is why proper maintenance
is important and necessary. Service hot water 140°F maximum, is
recommended with flow through, drain type units for increasing capacity.

heating system is important for efficient and safe operation. Your heating
dealer should perform humidifier service at the same time.
All models are equipped with an in-line water strainer and orifice as
shown below. These parts should be inspected and cleaned periodically to
