REFRESHING MOISTURE . . .
AS NATURE INTENDED
Congratulations on your excellent choice and sound investment in
this addition to your home comfort system.
Your new unit is among the most energy--efficient and reliable
home humidifiers available today. 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.
YOUR HOME HUMIDIFIER
YOUR HOME CAN BE DRIER THAN A DESERT
During the heating season, the air in your home can become
uncomfortably dry. This is because cold winter air holds very little
moisture. When outdoor air is warmed to average room
temperature, its relative humidity falls to even lower levels. Refer
to Fig. 2 for a comparison of the levels of relative humidity for a
few sample environments.
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
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 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. 3 and 4.

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:
S The 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.
S The 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.

S 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.
S The humidifier unit must be properly maintained on a regular
basis.
START--UP PROCEDURES
1. Open the saddle valve on the water supply line. (See Fig. 5.)
Set humidistat to the desired relative humidity. (See Fig. 6
and Table 1.)
2. Turn the furnace on and adjust the thermostat to a high temperature setting. Be sure that the furnace blower is operating.

5. Turn off the furnace. When the blower stops, look into the
humidifier to make sure the water is not flowing into the
unit.
6. Replace the cover assembly and fasten securely.
7. Now, turn the furnace on and set the thermostat for desired
room temperature.
SHUTDOWN PROCEDURES
To shut down your humidifier, close the saddle valve on the water
line. Then turn off the humidistat. When set to the OFF position,
the humidistat shuts off the electrical power to the solenoid valve
on the humidifier.
NOTE: If your home comfort system includes cooling, be sure the
water supply to your humidifier is turned off during the cooling
season.
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.
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 at the
beginning of every heating season
.
CLEANING PROCEDURES
1. Turn off all electrical power to the humidifier and furnace or
fan coil.
2. Turn off the humidifier’s water supply. (See Fig. 5.)
3. Disassemble the humidifier. The pad assembly can be removed from the side access door or the front cover. When
removing the side door, lift the pad assembly up by holding
the tabs and slide the assembly out. When removing the
front cover, disconnect the quick connects to the solenoid
valve, unscrew the 4 screws to the front cover, snap loose
the top and bottom catches, and lay the front cover aside.
After the front cover is off, lift the pad assembly up and
twist it out. The pad assembly consists of 4 parts; the distributor pan, frame, sump, and the evaporator pad. Pull the
distributor pan apart from the frame and the evaporator pad
can be removed. Do not force the evaporator pad in or out
without removing the distributor pan as this will distort the
pad.
4. Clean the humidifier’s external components.
5. Clean the internal components of your humidifier. Wash the
distributor pan with a mild detergent and warm water. Be
sure holes and slots in the pan are clean and unobstructed.
Wash the evaporator pad assembly in a detergent solution. If
there are scale deposits on the pad, soak it in ordinary
household vinegar. If the pad is covered by a heavy deposit
of scale, or if the local water supply has high sulfate or calcium content, replace the pad with a new one. Contact your
dealer for replacement part.
6. Reassemble your humidifier.
7. Turn on the electrical power and water supplies. Refer to the
start--up procedures.
