1.2 Steam nozzle
For smaller outputs of up to 4 kg/h, we offer a steam nozzle which can be
either fitted in air ducts, for instance, or used for direct room humidification.
The rules for the humidification distance (distance needed to mix the
steam adequately with air) must be observed here, too.
When the steam nozzle is employed, the length of the steam hose should not
exceed 1.5 metres.
1.3 Fitting the humidifier
All installation work must be performed by trained personnel. The customer himself is responsible for verifying
their qualifications.
When fitting the humidifier, use only the material supplied with the unit and observe the various minimum distances
that have been stipulated.
To open the humidifier, turn the screw, using the correct screwdriver, in an anti-clockwise direction; the door to the
water componentry or the electrics then opens. To close, simply push back into place (no screwing down is necessary).
Positioning the humidifier
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 you fit the humidifier as near as possible to
the steam-distribution pipes. The highest degree of efficiency is
attained when the humidifier is linked to the steam-distribution
pipe by the shortest possible steam hose.
When installing the double units (types 64, 90 and 130 kg/h) next
to each other, ensure that each drainage pipe is fed to a funnel
of adequate size.
1.4 Fitting the steam-distribution pipe
All installation work must be performed by trained personnel. The customer himself is responsible for verifying
their qualifications.
The visible jet of steam issuing from the steam-distribution pipe dissipates in the air only after a certain distance.
In order to prevent condensation, a certain minimum distance to other parts of the installation (such as ventilators,
filters or pipe bends) must, therefore, be maintained.
The steam-distribution pipes can be fitted either vertically or horizontally, though you must ensure that the steam
outlets are always vertical to the air flow. If fitted horizontally, these apertures must be at the top.
An adhesive template is supplied with each steam-distribution pipe to facilitate installation in, for instance, 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.
