INTRODUCTION
Thank you for purchasing this humidifier.
To assure its dependability, spend a few minutes now 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.
Proper humidity control can alleviate 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 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 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 typical process of humidification begins when
water flows through the humidifier valve and soaks the water
panel. Hot, dry air from the furnace passes through the panel and
absorbs the water. Then, this moisture--laden air is distributed
throughout the house via the ductwork. See Fig. 2 and 3.

OPERATING YOUR HUMIDIFIER
Your new humidifier is designed to operate as part of your home
heating system. It will perform at maximum efficiency if these
recommendations are followed:
SThe humidifier is controlled by a humidistat. Adjust the
humidistat setting according to the outside temperature. Refer to
Table 1 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.

SThe humidistat is included with the humidifier. Continuous
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 air cleaner
offers the added benefit of full--time air filtration.

SSupply-- 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.
SThe humidifier unit must be properly maintained on a regular
basis.
SDuring the summer season, turn the humidistat to the “off”
position.
PERFORMING ROUTINE MAINTENANCE
With the proper maintenance and care, your humidifier will operate
economically and dependably. Maintenance can be accomplished
easily by referring to the following directions. However, before
performing any maintenance, consider the following important
safety precautions.
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal injury
or death.
The following procedures could expose hazardous live
components. Only a trained, experienced service person
should install this humidifier. Before performing installation,
service or maintenance operations on unit, turn off all power to
unit. TAG DISCONNECT SWITCH WITH LOCKOUT
TAG.
!WARNING
CUT HAZARD
Failure to follow this caution may result in personal injury.
Sheet metal parts may have sharp edges or burrs. Use care and
wear appropriate protective clothing and gloves when
handling parts.

Your humidifier has been designed for easy disassembly to
simplify cleaning and servicing. Your unit must be kept clean to
maintain its efficiency.

Regular inspection allows you to determine the cleaning schedule
best suited to your humidifier’s operating conditions. The
frequency for required maintenance will depend most upon the
quality of the available water supply. In areas where hard water and
high mineral content are prevalent, more frequent cleaning and
servicing may be required.
At minimum, the humidifier will need to be cleaned and the
water panel replaced at the beginning of every heating season.
CLEANING PROCEDURES
1. Turn off all electrical power to the humidifier and furnace or
fan coil. Unplug the humidifier from the electrical outlet.
2. Turn off the humidifier’s water supply. (See Fig. 5.)

3. Disassemble the humidifier. The panel assembly can be re-
moved from the front cover. When removing the front cov-
er, unlatch the bottom catches, and lay the front cover aside.
After the front cover is off, remove the water distribution
tray by sliding it out. Pull the water panel assembly out and
replace it with Part No. CAR--0909. Do not force the water
panel in or out without removing the water distribution tray,
as this will distort the panel.

water distribution tray with a mild detergent and warm wa-
ter. Be sure holes and slots in the tray are clean and unob-
structed. Contact your dealer for replacement water panel

BEFORE YOU REQUEST
A SERVICE CALL
CHECK FOR THESE EASILY SOLVED PROBLEMS:
SCheck the main power disconnect switch. Verify that the circuit
breakers are on and that fuses have not blown. If you must reset
breakers or replace fuses, do so only once. Contact your servicing
dealer for assistance if the breakers trip or the fuses blow a second
time.
SIf the humidity level is too low, check the humidistat setting.
Confirm that the saddle valve is turned completely on. Check the
water panel, and clean or replace the panel as necessary.
SCheck for sufficient airflow. Check the furnace filter or air cleaner
for excessive accumulations of dirt. Check for blocked return-- or
supply--air grilles. Be sure grilles are open and unobstructed.
SIf water drips from the humidifier, check the drain hose for kinks
or obstructions.
If your comfort system still fails to operate properly, contact your
servicing dealer for troubleshooting and repairs. Specify your
apparent problem, and state the model and serial numbers of your
equipment. (You should have them recorded below in this
booklet.) With this information, your dealer may be able to offer
helpful suggestions over the phone, or save valuable time through
knowledgeable preparation for the service call.
REGULAR DEALER MAINTENANCE
In addition to the routine maintenance that you perform, your
humidifier should be inspected regularly by a properly trained
service technician. The inspection (preferably each year, but at least
every other year) should include the following:
SRoutine inspection of the humidifier. Cleaning, if necessary.
Replacement of the water panel, annually.
SA check of all electrical wiring and connections.
SA check of water connections to the unit.
SOperational check of the complete comfort system to determine
actual working condition. Necessary repair and/or adjustment
should be performed at this time.
Your servicing dealer may offer an economical service contract that
covers seasonal inspections. Ask for further details.
