in this addition to your home comfort system.
Your humidifier represents both the latest in engineering development and the culmination of many years of experience from
one of the most reputable manufacturers of comfort systems.
Your new unit is among the most energy-efficient and reliable
home humidifiers available today. To assure its dependability,
spend a few minutes with this booklet no w. Learn about the operation of your humidifier and the small amount of maintenance
it takes to keep it operating at peak ef ficiency.
With minimal care, your humidifier will provide you and your
family with moist, spring-fresh air — from season to season and
year to year.
YOUR HOME HUMIDIFIER
YOUR HOME CAN BE DRIER THAN DEATH VALLEY
During the heating season, your home can become uncomfortably dry. This is because cold winter air holds very little moisture. When outdoor air is warmed to a v erage room temperature,
its relative humidity falls to even lower levels. Refer to Table 1
for a comparison of the levels of relati ve humidity for a fe w sample environments.

the large evaporator pad. Hot, dry air from the furnace passes
through the pad and absorbs the water . Then, this moisture-laden
air is distributed throughout the house via the ductwork. See Fig.
1, 2, and 3.

Parched air can cause the wood used in the construction of y our
house and furnishings to dry , crack, and split. Draperies and upholstery may age prematurely. Annoying static electric shock
and cling are more prevalent. Your throat, nasal passages, sinuses, and skin are more susceptible to irritating dryness. You
may even have to set the thermostat higher than otherwise necessary — just to feel warm.
MOISTURE MAKES A REFRESHING DIFFERENCE
Proper humidity control can alleviate problems caused by e xcessive dryness. Furnishings and fabrics take on a more lustrous
appearance. Houseplants thrive. Static electricity is signifi cantly
reduced in a properly humidified home. Your family will breathe
more easily and find relief from the cool, drafty feeling commonly experienced in overly dry homes. The additional moisture
supplied by your humidifier may enable you to reduce the temperature setting on your thermostat — without any loss of indoor
comfort.
HOW Y OUR HUMIDIFIER WORKS
Your humidifier adds water molecules to the air inside your
home. Although the rate of humidification is variable, it may
exceed one-half gallon of water per hour. That’s a healthy drink
for a dry household. The typical process of humidification begins when water flows through the humidifier valve and soaks

OPERA TING YOUR HUMIDIFIER
Y our ne w humidifier is designed to operate as par t of your home
heating system. It will perform at maximum efficiency if these
recommendations are followed:
•
The humidifier is controlled by a humidistat. Adjust the
humidistat setting according to the outside temperature. Refer
to Table 2 as a general guide. If after several days, the air in
your home seems too moist, lower the humidistat setting. Condensation on single-pane windows indicates excessive moisture. If the air is too dry, increase the setting. Dry throat and
nasal passages indicate dry air.
•
All models come with a humidistat. Controlled blower operation provides for constant humidification. It may also contribute to greater personal comfort because continuous blower
operation minimizes temperature differences throughout the
home. Furthermore, a system equipped with an electronic air
cleaner offers the added benefit of full-time air filtration.
