HE120 BY-PASS DRUM HUMIDIFIER

WELCOME...

to the comfortable world of humidified air. With your Honeywell humidifier you will
notice a decrease in dry skin. You’ve also taken the first step to stopping the “zapping”
created by walking on your carpet and touching your TV, computer, metal door knob or
your pet. You can even put away your glue bottle because your furniture and
woodwork will stop drying out. Congratulations! You have just made a great investment
in your home comfort.

Indoor air quality products from Honeywell are designed to help make your home more
comfortable—from zoning products that allow you to control the temperature in
individual areas of the home to humidifiers and comfort control centers that help
balance the moisture content of your indoor air.

Honeywell is proud to be a partner of the American Lung Association® Health House®

HOW YOUR HUMIDIFIER WORKS

Your Honeywell humidifier uses the principle that vapor (evaporated water) is created
when warm air blows over a water soaked area. As the vapor circulates, the relative
humidity rises.

Your humidity control monitors the relative humidity and activates the humidifier
accordingly. The humidifier has a water supply that disburses water evenly over a
humidifier pad. The warm dry air from the furnace passes over the humidifier pad and
picks up the moist air to circulate it through your home.

Humidified air feels warmer and more comfortable so you may be able to lower your
thermostat heating setpoint and save money on your heating fuel bills. The end result
is that your humidifier gives you a comfortable environment that is also energy
efficient.

OPERATING YOUR HUMIDIFIER

Your HE120 Honeywell humidifier is controlled by
the Humidity Control that is installed either on the
return air duct or on an interior wall in your living
area. 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 for
optimizing the humidity level while reducing the
moisture condensation on your windows. The table
below can also be used to adjust the humidity
control to the recommended setting.

NOTE: As the outside temperature drops, the recommended humidity control setting

is lowered to accommodate for the effects of dewpoint. These settings should
reduce the accumulation of moisture and ice on your windows and in other
areas of your home.

Some indoor activities such as cooking, showering and clothes drying can cause
excessive levels of humidity and start the accumulation of moisture on your 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 your home to remove the moisture.

MAINTAINING YOUR HUMIDIFIER

A regular maintenance program prolongs the life of your humidifier and provides a
more comfortable home. The frequency of cleaning will depend on the condition of
your water.

deposits are more difficult to clean than soft water deposits.
