Minimum distances to be observed
To prevent the water vapour, that is emitting from the steam distribution pipe, from condensing on
downstream system components, a minimum distance to the steam distribution pipe must be observed
(depends on the humidification distance “B
N
”).

Installation notes and dimensions
The steam distribution pipes are designed for either
horizontal
installation (on the duct wall) or, with
accessories, for
vertical
installation (in the duct floor). The
outlet orifices should always point
upwards and at right angles to the airflow
.
If possible, the steam distribution pipes should be installed on the
pressure side
of the duct (
max.
duct pressure 1500 Pa
). If the steam distribution pipes are installed on the suction side of the duct,
the
maximum vacuum must not exceed 800 Pa
.
Select a location for the installation, tailored to suit your duct (see the following illustrations) and
position the steam distribution pipes in the duct so that a uniform distribution of steam is achieved.
