REFRESHING MOISTURE . . .
AS NATURE INTENDED
Congratulations on your excellent choice and sound investment
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 no w with this booklet. Learn about the operation of your humidifier and the small amount of maintenance
it takes to keep it operating at peak efficiency .
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
Y OUR 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 ductw ork. See Fig.
1, 2, and 3.

Parched air can cause the wood used in the construction of your
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 ov erly 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 part 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. Continuous blower oper ation 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.

•
Supply- and return-air grilles should not be blocked by items
such as drapes, furniture, and toys. Restricted airflow reduces
the efficiency of the humidifier , as well as that of the whole comfort system.
•
The humidifier unit must be properly maintained on a regular
basis.
STARTUP PROCEDURES
1. Open the saddle valve on the w ater supply line. (See Fig. 4.)
Set humidistat to the desired relative humidity. (See Fig. 5
and T able 2.)
2. Turn the furnace on and adjust the thermostat to a high temperature setting. Be sure that the furnace blower is operating.
3. Check to see if water is flowing into the humidifi er.

On a Model HUMCCLBP or Model HUMCCLFP humidifier, loosen the thumbscre w that holds the distributor cover to the
top of the cabinet. Lift up the distributor cover slightly to make
certain that water is flowing from the solenoid valve into the
distributor pan. Do not lift the cover off the cabinet more than
1 in. when water is flowing. (See Fig. 6 or 7 according to the
model you own.)

•
On a Model HUMCCSBP humidifier, gently pull the latch
that secures the access door. Remove the door. Check to see if
water is flowing from the solenoid v alve into the e vaporator pad.
(See Fig. 8.)
•
On a Model HUMCCSFP humidifier, open the side door or
the front cover. If the front cover is opened, hold the pad assembly in place. Check to see if water is flowing from the solenoid
valve into the distributor pan. (See Fig. 9.)
•
On a Model HUMCCWTR unit, look through the window on
front of the unit to see that the evaporator pad is rotating and
water is flowing. (See Fig. 10.)
The Model HUMCCWTR is controlled by a float valv e. T urning
off the furnace will not affect the water flow until float level is
achieved. (See Fig. 11.)

4. Turn off the furnace. When the blower stops, look into the
humidifier to make sure the water is not flowing into the
unit.
5. Replace the cover assembly and f asten securely.
6. Now, turn the furnace on and set the thermostat for desired
room temperature.
