REFRESHING MOISTURE...
AS NATURE INTENDED

Congratulations on your excellent choice and sound investlnent
in this addition m your holne COlnfort system.

Your hulnidifier represents both the latest in engineering devel-

oplnent and the cuhnination of lnany years of experience t}Oln
one of the lnost reputable lnanufacturers of comfort systems.

Your new unit is alnong the most energy-efcient and reliable

holne hulnidifiers available today. To assure its dependability,
spend a few lninutes now with this booklet. Learn about the op-
eration of your hulnidifier and the small alnount oflnaintenance
it takes to keep it operating at peak efficiency.

With lninilnal care, your hulnidifier will provide you and your
_amily with lnoist, spring-fresh air froln season to season and

year to year.

YOUR HOME HUMIDIFIER

YOUR HOME CAN BE DRIERTHAN DEATH VALLEY

During the heating season, your holne can becolne uncolnfort-
ably dry. This is because cold winter air holds very little lnois-
rare. When outdoor air is warmed to average rooln telnperamre,
its relative hulnidity £hlls to even lower levels. Refer to Table 1
for a comparison of the levels of relative humidity for a few sam-

ple enviromnents.

the large evaporator pad. Hot, dry air [}oln the furnace passes
through the pad and absorbs the water. Then, this lnoisture-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 your

house and furnishings to dry, crack, aM split. Draperies and up-

holstery may age prelnaturely. Amaoying static electric shock
and cling are lnore prevalent. Your tlaoat, nasal passages, si-

nuses, and skin are more susceptible to irritating dryness. You

may even have to set the therlnostat higher than otherwise nec-
essary just to feel warm.

MOISTURE MAKES A REFRESHING DIFFERENCE

Proper hulnidity comrol can alleviate problelns caused by exces-
sive dryness. Furnishings and fabrics take on a more lustrous
appearance. Houseplants tl_ive. Static electricity is significantly
reduced in a properly hulnidified home. Your £hmily will breathe
lnore easily and ilnd relief from the cool, drafty feeling coin-
lnonly experienced in overly dry holnes. The additional lnoisture
supplied by your humidifier may enable you to reduce the tem-

perature setting on your therlnostat without any loss of indoor

COlnfort.

HOWYOUR HUMIDIFIERWORKS

Your hulnidifier adds water lnolecules to the air inside your
holne. 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 lmlnidification be-
gins when water flows through the humidifier vah,e and soaks

OPERATING YOUR HUMIDIFIER

Your new hulnidifier is designed to operate as part of your home
heating system. It will perforln at lnaximuln efciency if these

recolranendations are followed:

• The hulnidifier is comrolled by a hulnidistat. Adjust the
hulnidistat setting according to the outside telnperature. Refer
to Table 2 as a general guide. If after several days, the air in
your home seems too moist, lower the humidistat setting. Con-
densation on single-pane windows indicates excessive mois-
ture. 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 hulnidification. It may also contrib-
ute to greater personal COlnfort because continuous blower
operation minimizes telnperature differences throughout the
home. Furtherlnore, a system equipped with an electronic air

cleaner offers the added benefit of full-tilne air filtration.

• Supply- and return-air grilles should not be blocked by items
such as drapes, flmfiture, and toys. Restricted airflow reduces
the efficiency of the humidifier, as well as that of the whole com-
fort system.

• The humidifier unit lnUStbe properly lnaintained 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.)

2. Turn the fimmce on and adjust the therlnostat to a high tem-
perature setting. Be sure that the fitmace blower is operating.

3. Check to see if water is flowing into the humidifier.

• On a Model HUMCCLBP or Model HUMCCLFP humidifi-
er, loosen the thulnbscrew that holds the distributor cover to the

mp of the cabinet. Lift up the distributor cover slightly to lnake
certain that water is flowing from the solenoid valve into the
distributor pan. Do not lift the cover offthe cabinet more than

1 in. when water is flowing. (See Fig. 6 or 7 according to the

lnodel you own.)

• On a Model HUMCCSBP humidifier, gemly pull the latch
that secures the access door. Relnove the door. Check to see if

water is flowing froln the solenoid valve into the evaporator pad.
(See Fig. 8.)

• On a Model HUMCCSFP hulnidifier, open the side door or
the front cover. If the front cover is opened, hold the pad assem-
bly in place. Check to see if water is flowing from the solenoid
valve imo 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 valve. Turning
off the fimmce 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 *hsten securely.

6. Now, mrn the furnace on and set the thermostat for desired
rooln telnperature.
