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. 

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.

DO NOT 

install the humidifier where freezing

conditions could occur or where accidental
overflow could cause water damage to the
home or property.

DO NOT

install the humidifier where the

temperature will exceed 180° F. Excessive heat
may cause softening and distortion of the
plastic housing.

The installation of a water filter may reduce
the potential clogging of the nozzle and
solenoid valve in hard water applications
