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.

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.

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.
