IMPORTANT
Please read these instructions and keep them in your records.
OPERATING YOUR HUMIDIFIER
Humidifiers are controlled by the Convertible
Humidity Control. The convertible humidity control is
installed either on an 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 dial. Match the dial setting to the
outdoor temperature for optimizing the humidity
level while reducing moisture condensation on your
windows. The table below can also be used to
adjust humidity control to the recommended setting.
NOTE: As outside temperature drops, the recommended humidity control setting is
lowered to adjust for effects of dewpoint. These settings should reduce accu-
mulation of moisture and ice on your windows and 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.
HOW YOUR HUMIDIFIER WORKS
Your 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 dispenses water evenly over the
antimicrobial humidifier pad. The warm dry air, from the furnace, passes over the
humidifier pad and picks up the moist air to circulate it throughout your home.

Humidified air feels warmer and more comfortable so you may be able to lower your
thermostat heating setpoint, which saves money on your heating fuel bills. The end
result is that your humidifier gives you a cleaner, more comfortable environment that is
also energy efficient.
MAINTAINING YOUR HUMIDIFIER
A regular maintenance program prolongs the life of your humidifier and provides a
more comfortable home. Frequency of cleaning depends on the condition of your
water. You can use either hard or soft water in your humidifier, but hard water mineral
deposits are more difficult to clean than soft water deposits. For optimum performance,
replace the antimicrobial pad once a year. Use the following procedure to clean your
humidifier.

operating.
•Reset circuit breaker or replace fuse.
•Check that the furnace power is on.
•Check all external wiring connections.

•Call a heating contractor.
Rapid air changes.
Drafts (cold air is dry
and is an added load
to humidifier).
•Keep doors and windows closed.
•Close fireplace damper if not using.
•Minimize exhaust fan running time.
•Seal around doors and windows.
High
humidity
Condensation on
walls.
•Turn off humidity control and water until
condensation is completely evaporated.
Heavy condensation
on windows.
•Turn humidity control low enough to eliminate
bath and cooking condensation moisture. If
moisture persists, more ventilation is needed.
