Page 2: Table Of Contents
Introduction You have purchased a NORDMANN steam humidifier which, provided you observe the operating instructions, will ensure fully automatic operation and reliable, low-maintenance service. Therefore, read these operating instructions carefully and pay particular attention to the safety instructions and warnings. - Page 3 Apart from these safety instructions, you should observe all national and local regulations. Proper use The NOVAP 3000 steam humidifiers are intended solely for indirect (via a steam-distribution pipe in a ventilation duct) or direct (with either a separate or a humidifier-mounted fan) humidification. Used in any other way, or in a way that goes above and beyond the one described above, is contrary to its intended usage.

Page 7: Steam Nozzle
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 vaporisation lines (lines needed to mix the steam adequately with air) must be observed here, too. -
Page 8: Fitting The Steam-Distribution Pipe
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. - Page 9 Fig. 17 A > 300 Fig. 18 A > 350 B = 0.5 A B = min. 150 C = 0.3 A D = min. 100 Fig. 19 A > 500 Fig. 20 A > 500 B = min. 100 B = min.

Page 10: Fitting The Blowers
1.5 Fitting the blowers All installation work must be performed by trained personnel. The customer himself is responsible for verifying their qualifications. The steam blower for distributing the steam in the room can be fitted either directly onto the humidifier itself (excepting types 32, 45, 64 and 90 kg) or onto a wall. -
Page 11: Laying The Steam Hose
Installation material If a hose is used for the steam line, it must be the original one supplied by NORDMANN. If other hoses are utilised, NORDMANN cannot be held responsible for any damage that may occur. A hose clamp should be used to link the hose to the steam-distribution pipe. -

Page 17: Putting Into Operation
The electronic control system, with its highly-integrated microcontroller, regulates the vaporisation process in accordance with a new principle developed by NORDMANN which allows rapid output changes to be made. The humidifier adapts itself fully automatically to the quality of the water used. -
Page 18: The Steam Cylinder
We recommend that you keep a spare cylinder in stock for each unit. NORDMANN’s steam cylinders are so economical that it is usually cheaper to replace the cylinder than to clean it. To clean the cylinder, it should first be emptied by pressing the black button for manual drainage located on the electronic print (see Fig. - Page 19 Lifetime of a steam cylinder at 100% steam output º DH (German hardness) °d Härte 1°DH = 1,25° English hardness 1°DH = 1,79° French hardness 1°DH = 1,05° American hardness 1°DH = 17,9 mg/I CaCo (ppm) without* SC-System with SC-System *but cylinder is flushed periodically Hours t (h)

Page 21: Indications Of The Two-Colour Led
4.7 Indications of the two-colour LED The newly-developed electronic controls unit with microcontroller continuously monitors the operations of the NOVAP 3000 humidifier. Any deviations from the operating condition (U codes) are shown with the two-colour LED. The status of the LED can be shining continuously or flashing in the red and green colours. -
Page 22: Remote Indication
The standard, potential-free relay output enables the collective alarm message to be displayed remotely. 4.10 Safety functions NORDMANN humidifiers are protected against running dry, i.e. the power is cut off automatically as soon as the electrodes in the steam cylinder protrude above the water level. -

The customer is responsible for verifying the qualifications of the technicians concerned. Before removing the electronics unit, all power to the humidifier must be switched off. -
Page 25: Rectifying Faults
6. Rectifying faults 6.1 The humidifier produces insufficient or no steam When a fault occurs, the problem is often sought only on the humidifier, though the fault may have been caused by a problem in the plant. For successful trouble-shooting, some knowledge of plant technology (air-conditioning, controls) is necessary. -
