Installation notes
The steam distribution pipes are designed for either
horizontal
installation (on the duct wall) or, with ac-
cessories, 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 1000 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.
