4. Run 1/2 in. (12.7 mm) ID drain line from barbed fitting on
water treatment system to floor drain.
5. Run 1/4 in. (6.35 mm) OD copper tubing from water
treatment system to humidifier.
IMPORTANT
Do not overtighten the compression nut. Moderate
tightness prevents leaking.
CAUTION
Flooding Hazard.
Can cause water damage to equipment or home.
Connect humidifier overflow drain to a suitable waste
drain.
6. Use a male 3/8 in. NPT fitting (not supplied) or a 3/4 in.
female NPT fitting, standard garden hose (not supplied)
to connect the overflow provision of the humidifier to a
suitable waste drain.
7. Support the drain line at several locations to prevent
kinks. Be sure to provide support near any heat source.

CHECKING INSTALLATION
After installation is complete, use the following procedure to
check humidifier operation:
1. Turn on the humidifier water supply.
2. Plug in the humidifier and check that the humidifier has
power. Wait a few minutes for the reservoir to fill.
3. Turn the Convertible Humidity Control to the highest
setting.
4. Check that the furnace blower comes on to circulate the
moist air. The blower may take as long as fifteen
minutes to turn on.
5. Reset the Convertible Humidity Control to a comfortable
setting.

OPERATION

The HE440A Humidifier is controlled by the Convertible
Humidity Control that is installed either on the interior wall in
the living area or on the return air duct.
— Choose the humidity control setting using the combination
relative humidity/outdoor temperature setting scale on your
humidity control.
— Match the dial setting to the outdoor temperature to
optimize the humidity level while reducing the moisture
condensation on your windows.
— Use Table 2 to adjust the humidity control to the
recommended setting.
NOTE: As the outside temperature drops, lower the
recommended setting to accommodate the effects of
dewpoint. These settings should reduce the
accumulation of moisture and ice on the windows and
in other areas of the house.
Some indoor activities such as cooking, showering and clothes
drying can cause excessive levels of humidity and start the
accumulation of moisture on the windows.
NOTE: If this condition persists for more than a few hours, set
the humidity control to the lowest setting to turn off the
humidifier. If the condition does not improve, ventilate
the house to remove the moisture.

The HE440A Humidifier uses the principle that hot water
creates water vapor. As dry air and vapor mix, the relative
humidity of the air rises. The humidity control monitors the
relative humidity and activates the humidifier accordingly.
When the humidity control calls for humidity, the humidifier
underwater heater starts heating the water in the humidifier
reservoir. When the water is warm enough, the humidifier
activates a relay that turns on the furnace fan. The warm dry
air from the furnace picks up the water vapor and circulates it
through the home. The fan continues to circulate the air until
the water cools down and then turns off the fan.
Humidified air feels warmer and more comfortable so you may
be able to lower the thermostat heating setpoint and save
money on heating fuel bills to give you a more comfortable
environment that is also energy efficient.
