FAN DISTRIBUTION UNITS
Fan distribution units are available for use in areas which do not
have duct systems or where duct air temperatures are too low
to provide sufficient humidification. For example, in computer
areas, the desired relative humidity may not be possible in the
conditioned space without causing condensation in the duct.
Fan distribution units may be either remote mounted or directly
mounted on the humidifier unit.

are shipped as a complete assembled unit. In this case, a 12-wire

connection (Green). This connection is already assembled in the
factory.

Fan distribution units must be mounted securely on a level and
plumb surface at least three feet below the ceiling for a Model
HXBHB and at least four feet below the ceiling for a Model HXBHC
to prevent condensing on the ceiling surface. Allow 20 feet in front
of the HXBHB and 30 feet in front of the HXBHC for the steam to
be absorbed into the air. Do not mount the units above any items
that would be damaged if a water leak or spitting were to develop.
