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.
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.
Cleaning Humidifier
(Every 1 to 3 Months Depending on Water Quality)
CAUTION
Voltage Hazard.
Can cause electrical shock
and equipment damage.
Disconnect power and shut off water supply before installing or servicing.
IMPORTANT
Never oil any part of the humidifier.
Use the following steps to clean your Honeywell humidifier:
1. Disconnect the power and turn off the humidifier water supply.
2. Remove the humidifier cover by lifting the bottom of the cover upward.
3. Lift up the drum shaft from the bearing end and slide it out of the motor coupling
to remove the drum assembly. See Fig. 1.
NOTE: You will encounter some resistance when removing the drum shaft until you
hear an audible click.
4. Remove the drum from the assembly.

8. Clean all humidifier parts in a 50% solution of vinegar (or a humidifier cleaner)
and water. Soak overnight to remove stubborn deposits.
NOTE: Replace humidifier pad yearly with the new Honeywell Drum Humidifier Pad
(Part no. HC12A1015). The actual frequency depends on the quality of the
water used.
9. After the humidifier components are clean, reassemble the humidifier by
reversing the order of steps 1 through 7.
NOTE: Be sure that the drum shaft is completely seated-listen for the click.
10. Verify the humidifier operation by following the steps in the Checking Your
Humidifier Operation section.
Start of Humidification Season
Replace the humidifier pad with a new Honeywell Drum Humidifier Pad (Part no.
HC12A1015) at the beginning of the heating season. Follow the cleaning instructions
to replace the pad and check for proper operation.
End of Humidification Season
Clean the humidifier and shut it off at the end of the heating season. Follow the
cleaning instructions, steps 1 through 9, to shut down the device for the season.

IMPORTANT
Be sure the humidifier power is off and the humidifier water pan is empty.
Vacation
When leaving on vacation, turn off the humidifier water supply and your humidity
control. Turn on the humidifier water supply and reset your humidity control when you
return.
CHECKING YOUR HUMIDIFIER OPERATION
After winter startup or maintenance, use the following steps to check the humidifier
operation:
1. Turn on the humidifier power and water supply.
2. Open By-Pass Damper (if installed).
3. Check the water level in the humidifier water pan; water level setting should be
1-3/8 in.
NOTE: Turn the valve adjustment screw, located on the water valve inside the
humidifier, clockwise to lower the water level and counter clockwise to raise it.
4. Turn the Humidity Control to the highest setting.
5. Check that the humidifier pad is rotating.
6. Reset the thermostat and Humidity Control to a comfortable setting.
TROUBLESHOOTING YOUR HUMIDIFIER
Problem What To Look For What To Do
Low humidity Furnace blower not
operating. •Reset circuit breaker or check for blown fuse. •Check that the furnace power is on.
•Check all external wiring connections.
•Check the humidity control setting.
•Call a professional heating contractor.
Rapid air changes.
Drafts (cold air is dry
and is an added load
to the humidifier).
•Keep doors and windows closed.
•Close fireplace damper when not in use.
•Keep exhaust fan running time to a
minimum.
•Seal around doors and windows.
High humidity Condensation on
walls. •Turn off the humidity control and water until condensation is completely evaporated.
Heavy condensation
on windows. •Turn humidity control down low enough to eliminate condensation caused by moisture
from bathing, mopping, cooking, etc. If
moisture persists, more ventilation is
needed.

HUMIDIFICATEUR À DÉRIVATION À TAMBOUR HE120
69-1110EF—02 10
FONCTIONNEMENT DE L'HUMIDIFICATEUR
L'humidificateur Honeywell fonctionne selon le principe suivant : de la vapeur (eau
évaporée) se forme lorsque l'air chaud passe sur une surface imbibée d'eau; en
circulant, la vapeur fait augmenter l'humidité relative.
Le régulateur d'humidité surveille l'humidité relative et fait fonctionner l'humidificateur
selon les besoins. L'humidificateur est muni d'un système d'alimentation qui distribue
uniformément de l'eau sur un tampon. L'air sec et chaud de l'appareil de chauffage
circule au-dessus du tampon et capte l'air humide pour le faire circuler dans la maison.
L'air humidifié semble plus chaud et il assure un meilleur confort; il est donc possible
d'abaisser le point de consigne du thermostat et, ainsi, de diminuer les coûts de
chauffage. Non seulement l'humidificateur assure plus grand confort, il permet de
réaliser des économies d'énergie.
UTILISATION DE L'HUMIDIFICATEUR
L'humidificateur Honeywell HE120 est commandé
par un régulateur d'humidité qui est installé soit sur
une gaine de retour d'air, soit sur un mur à l'intérieur
d'une pièce utilisée. Pour régler le régulateur
d'humidité, consulter l'échelle combinée de l'humidité
relative et de la température à l'extérieur apposée sur
le régulateur. Il faut tenir compte de la température à
l'extérieur pour optimiser le degré d'humidité et
réduire la condensation dans les fenêtres. Le tableau
ci-dessous peut également servir à choisir le réglage
recommandé.
REMARQUE : Lorsque la température à l'extérieur diminue, le point de consigne du
régulateur d'humidité doit être abaissé pour tenir compte des effets du
point de rosée. Ces réglages permettent de réduire l'accumulation de
condensation et de glace dans les fenêtres et ailleurs dans la maison.
Certaines activités comme la cuisson, les douches et le séchage des vêtements
peuvent produire une humidité excessive dans les fenêtres.
