3.3 Fitting the humidifier
For the fitting of the humidifier use the material supplied with the unit. Observe the various minimum distances as
indicated in figure 3.5.
Ensure that there is sufficient room to perform servicing and maintenance work and that the unit is easily accessible.
To facilitate such work, mount the unit at eye level.
We recommend that the unit is installed as near as possible to the steam-distribution pipe. The highest degree of
efficiency is attained when the humidifier is linked to the steam-distribution pipe by the shortest possible steam
hose.
3.4 Fitting the steam-distribution pipe
General guidelines for the installation:
The visible jet of steam issued from the steam-distribution pipe dissipates in the air only after a certain distance.
In order to prevent condensation, a certain distance to other parts of the installation (such as ventilators, filters or
pipe bends) must be maintained.
The steam-distribution pipes can be fitted either vertically or
horizontally, though it must be ensured that the steam outlets
are always vertical to the flow. If fitted horizontally, these
apertures must be at the top.
An adhesive template is supplied with each steam-distribution
pipe to facilitate the installation, for example in an air duct.
NORDMANN's steam-distribution pipes are designed so that, if
fitted straight, there is automatically a slight decline of 3 %
which ensures that any condensate flows back again.
The ends (reverse side of mounting plate) of the longer steam-
distribution pipes (types 35-900, 35-1200 and 35-1500) are
equipped with an M6 fixing bolt.
