REFRESHING MOISTURE... AS NATURE
INTENDED
Congratulations on your excellent choice and sound invest­
ment in this addition to your home comfort system.
Your humidifier represents both the latest in engineering
development and the culmination of many years of experi­
ence from one of the most reputable manufacturers of com­
fort systems.
Your new unit is among the most energy-efficient and reli­
able home humidifiers available today. To assure its depend­
ability, spend just a few minutes with this booklet now.
Learn about the operation of your humidifier and the small
amount of maintenance it takes to keep it operating at peak
ef&ciency.
With minimal care, your humidifier will provide you and
your fEimily 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 uncom­
fortably dry. This is because cold winter air holds very little
moisture. When outdoor air is warmed to average room tem­
perature, its relative humidity falls to even lower levels.
Refer to Table 1 for a comparison of the levels of relative
humidity for a few sample environments.
Table 1—Relative Humidity Comparison Chart
description of the process: Water flows through a valve to
soeik the large evaporator pad. Hot, dry air from the furnace
passes through the pad smd absorbs the water. Then, this
moisture-laden air is distributed throughout the house via
the ductwork. See Figs. 1, 2, and 3.

Parched air can cause the wood used in the construction of
your house and furnishings to dry, crack, and split. Draper­
ies and upholstery may age prematurely. Annoying static
electric shock is more prevalent. Your throat, nasal pas­
sages, 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 eilleviate problems caused by
excessive dryness. Furnishings and fabrics take on a more
lustrous appearance. Houseplants thrive. Static electricity
is significantly reduced in a properly humidified home. Your
family will breathe more easily and be relieved 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 YOUR 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 following is a brief
OPERATING YOUR HUMIDIFIER
Your new humidifier is designed to operate as part of your
home heating system. It will perform at maximum effi­
ciency if these recommendations are followed;
• If your humidifier is controlled by a humidistat, adjust
its 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. However, if the air is too dry, raise the setting.
Dry throat and nasal passages indicate dry air.
• If your system does not include a humidistat, consider
running the heating unit blower continuously—day and
night. Uninterrupted blower operation provides for con­
stant humidification. It may also contribute to greater per­
sonal comfort because continuous blower operation mini­
mizes temperature differences throughout the home. Fur­
thermore, a system equipped with an electronic air cleaner
offers the added benefit of full-time air filtration.
• Supply- and return-eiir grilles should not be blocked.
Drapes, furniture, and toys are some of the items commonly
found obstructing grilles. Restricted airflow reduces the
efficiency of the humidifier, as well as that of the whole com­
fort system.
• The humidifier unit must be properly maintained on a
regular basis.
STARTUP PROCEDURES
1. Open the saddle valve on the water supply line. See
Fig. 4. Set humidistat to the desired relative humidity.
See Fig. 5 and Table 2.
