Introduction
Introduction
The benefits of a properly humidified environment (3550% Relative Humidity) are many. They include both
personal comfort as well as the preservation of
furniture, draperies, carpets, wooden floors and
cabinets, paintings, pianos, etc.
Your home will be more comfortable at a lower
temperature (i.e.: 68° F) at 30-40% Relative Humidity
(RH) than at 71° to 72° F without controlled humidity.
Since every degree of temperature setback represents
about 3% of your heating costs, this can possibly
represent a significant annual savings.
During the heating season, cold air is brought into the
home and heated. When heated, this air dries out and
greatly increases its capacity to hold more moisture. By
using a humidifier, a source of water is provided to
satisfy this increased moisture holding capability,
rather than having it drawn from our body surface and
the surrounding furnishings in the home.

doors, and a dampered fireplace. Air exchange rate of .5 changes per hour.
An “Average Home” is insulated and has a dampered fire place, but there are no vapor barriers,
storm doors, or storm windows. Air exchange rate of 1.0 change per hour.
A “Loose Home” is generally one constructed before 1930, has little or no insulation, no storm
doors, storm windows, weather stripping or vapor barriers, and often no effective dampering of
fireplaces. Air exchange rate is as high as 1.5 changes per hour.

Output Capacity
Output Capacity
Increasing or decreasing the nozzle size or
water pressure to the humidifier can vary the
output capacity of this humidifier. It is
recommended that the humidifier not be
used at water pressures below 40 PSI,
otherwise, the mist may be affected.
Note:
Due to the operation cycle of the
furnace and humidifier, it may take
anywhere from 2 to 5 days to reach
the proper humidification level.
The following chart illustrates the capacity of
different nozzles at varying water pressures.
The output capacities shown are for water,
and are 1/2 the output capacity of the rated

Installation
Selecting a Location for the Unit
When selecting a location for the installation
of your humidifier, certain conditions must be
met for its proper operation. The
recommended location for this humidifier is
on the supply plenum, approximately 3”
downstream of the furnace. In narrow
plenum arrangements, the humidifier should
be mounted on the narrow side of the duct.
Select a location so that the spray from the
nozzle will not impinge on the furnace fan,
control switches, air conditioning or heat
coils.

Plenum
Humidifier
Nozzle
Thermostat
Furnace
The humidifier should be mounted so that
the furnace air carries the mist away from the
humidifier thermostat. The unit is specially
designed to allow the nozzle to be adjusted
so that the thermostat can be located
upstream from the nozzle. For plenum
mounting, the nozzle should always be
pointed in the up position. When the position
of the nozzle has been determined, tighten
the nozzle/solenoid valve mounting hardware
securely.

Start Up
Note:
1. Adjust the humidistat to the ON position
and turn the furnace on.
It may take several days for the
humidity level in the home to reach
comfortable levels.
2. Adjust the house thermostat to cause the
furnace to operate. The burner and
blower should turn on BEFORE the
humidifier.
3. The solenoid valve will make an audible
click when it operates, either on or off.
4. If necessary, adjust the furnace fan control
to a lower setting to allow the blower to
turn on before the humidifier turns on
and the blower turns off after the
humidifier is off.
5. Readjust the humidistat to the desired
setting (30-40% Relative Humidity is
recommended).
6. If condensation occurs on windows, lower
the humidistat setting until the
condensation has disappeared.

Operation
Operation of Humidifier
Recommended Relative
Humidity Levels vs.
Temperature
Your atomizing mister type humidifier
operates by dispersing a fine mist into the
warm air plenum of your furnace. The water
is then evaporated and carried into the home
by the furnace air flow. This humidifier is
recommended for areas where water mineral
content is low. Otherwise, a fine accumulation
of white dust may occur in either the ducts or
living areas. High mineral content will also
clog the nozzle causing an uneven spray
pattern or excessive dripping.
When wired properly, the humidifier will
operate only when the plenum temperature
rises to the internal thermostat setting, the
humidistat senses a need for humidity, and
the furnace blower is in operation. The
internal thermostat indicates the temperature
at which the humidifier will turn on. The
humidifier should activate after the furnace
blower comes on and shut off before the
furnace blower turns off. If this does not
occur, readjust the furnace fan switch as
required.

Note:
When shutting the humidifier down for
the summer months turn the water off
and clean any mineral accumulation
from the unit. Leave the water turned
off. If the furnace fan is to be used for
cooling purposes, disconnect power to
the humidifier or turn the humidistat to
the OFF position if applicable.
If applicable, set the humidistat in the
recommended range of 30-40% Relative
Humidity for automatic humidity control
during the heating season (a lower setting
may be used to control condensation on
single pane windows). Due to the operation
cycle of the furnace and humidifier, it may
take two to five days to reach the proper
humidification level.

Maintenance
Like your heating system and air conditioning
unit, periodic maintenance and cleaning are
required to ensure the safe and efficient
operation of your humidifier.
To improve the efficiency of your humidifier, and
to reduce the possibility of a health hazard, it is
recommended that you take the following
precautions:
• Follow the manufacturer’s recommended
cleaning and maintenance instructions.
• The amount of minerals and other impurities
in a water source can vary greatly, therefore
the frequency of cleaning the humidifier
also varies.
• During the heating season, check for film or
scale build-up on the atomizing nozzle and
drip sleeve on a monthly basis. Establish a
proper cleaning schedule to ensure the
efficiency of the humidifier.
• At the end of the winter humidification
season, drain and thoroughly clean the
humidifier.
Note:
The necessity to clean your
humidifier is substantially the
result of impurities coming in
through your water supply
which feeds the humidifier.
Other household dust,
containing biological and
microbial contaminants can
find its way into the air
handling system and
ultimately, the humidifier.
The humidifier is not the
source of these impurities.
