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 oor). The outlet orices should always point upwards

and at right angles to the airow.

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.
