I. PRINCIPLE OF OPERATION
II. OPERATING INSTRUCTIONS
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.
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).

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.
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.
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.
TABLE 2 – % Relative Humidity Guide
Outdoor Temperature (°F)
-10 0 10 20 30 40
1 10 10 10 15 20 25
2 10 10 15 20 25 30
3 10 15 20 25 30 35
4 15 20 25 30 35 40
5 20 25 30
Dial Setting
35 40 45
6 25 30 35 40 45 45
7 30 35 40 45 45 45
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%.
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.
- 4 - - 5 -
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.
TABLE 3 – Outdoor-Indoor Relative Humidity
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.
