DEVICE DESCRIPTION
The UV-FLOW .... C-NX is a controlled unidirectional flow device, with a powerful UV lamp inside and a narrow emission
peak at wavelength of 235.7 nm. (nanometers), which has a strong germicidal effect against all micro-organisms (molds,
bacteria and viruses).
There is also a parabolic, mirror bright aluminum surface, which generates UV ray parallel beams by reflection. These
beams pass through a black honeycomb laminated grid that directs UV rays to form a unidirectional flow ("blade UV").
When installed according to the instructions, this device can be used in the presence of people for intensive and
continuous air disinfection.
OPERATION
The UV-FLOW .... C-NX must be anchored at the wall and can be oriented so to generate a horizontal flow or a vertical
downward flow.
HORIZONTAL FLOW:
This arrangement will create a "zone of intense radiation" below the ceiling, which destroys all airborne microorganisms,
due to natural convection of air (see pic. 1)
The air, rich in microbes, is continuously treated and disinfected by the ultraviolet rays; a progressive decontamination
of bacteria, viruses and molds is made, decreasing the possibility of bacterial, viral transmissions and contaminations
in general.
Continuous operation ensures a permanent progressive healthy environment, especially in hospitals, schools,
restaurants, indoor workplaces such as offices, laboratories, etc. An extremely important disinfection activity can be done
in hospital intensive cares units, to prevent the spread of diseases such as TB and other transmissible pathologies through
air.
VERTICAL FLOW:
This arrangement is positioned above the doors of controlled contamination rooms (clean rooms), with air flow directed
downwards. This arrangement generates a vertical air flow which produces a barrier against germs (pic. 2).
For proper use you should create a decontamination area between two adjoining rooms, to be kept under microbiological
and hygienic control. This zone can be made simply by a double opening, door and Avant-door, just over the front door
wide and about 1.5 to 2 meters deep.
The use of the UV-C-FLOW .... NX allows intense disinfection of that contaminated air entering microbiologically con-
trolled rooms when doors are opened. It is necessary in healthcare where transmission of bacteria, viruses, and airborne
spores is highly probable.
The application is also needed for food production areas, where it is necessary to work in very good microbiological
conditions.
BENEFITS AND ADVANTAGES
BLOCK OF GERMS
Blocking the spread of germs from one place to another (in case of using VERTICAL flow). Then you can keep at
consistently low levels the entry of germs into "controlled contamination" rooms.
PHYSICAL ACTION AND ENVIRONMENTAL PROTECTION.
Treatment by UV-C rays is purely physical, and always achieves the same effect; Also, there are no problems of over-
dose and rooms are safe and practicable (when devices are off). Rather, many methods of chemical treatment involve
the use of dangerous products for the environment, and difficult to biodegrade, as well as the risk of contamination of
foodstuffs. Whereas, the use of chemicals it is likely to develop resistant microbial forms with consequent danger to
human health.
DEEP AND ONGOING DISINFECTION
UV-FLOW can work 24 hours over 24 in the presence of people, thus allowing to maintain a consistently low level of
microbial environment.
PRACTICABILITY AND SAVINGS.
The treatment is immediate and ready for use. The maintenance is minimal with low costs of both energy consumption
and repairs.

INSTALLATION
Decide the type of orientation to be given to the air flow: horizontal flow or vertical downward flow
HORIZONTAL FLOW:
The installation must be made by placing the brackets at 2.20 meters above the floor. In this way the flow will be slightly
upwards, which makes possible the continuous disinfection of the air circulating within the room, because of the natural
convective motions.
To cover your device, please refer to Table.1. During the installation phase, avoid directing the air flow towards objects
hanging from the ceiling, such as air conditioners, filters, etc., which would prevent its proper operation and could
cause unwanted downward reflections.

Rev. 2 Oct -2020
Pag. 8/16
VERTICAL FLOW:
The device must be placed above the doors of the
controlled contamination room (clean room), with air
flow directed downwards. Use the two supplied
stainless-steel brackets, anchoring them to the wall
with expansion bolts (8 to 10 mm.) or with self-
tapping screws.
This arrangement generates a vertical air flow which
produces barrier against germs (pic. 2).
For proper use you should create a decontamination
area between two adjoining rooms, to be kept under
microbiological and hygienic control. This zone
can be made simply by a double opening, door
and Avant-door system, just over the front door wide
and about 1.5 to 2 meters deep.
Of course, the doors should be normally closed
(preferably equipped with electrical or mechanical
locking, spring-return type). Normally, only one port
at a time must be opened and when one door is
opened, to allow entry of the decontamination area
the second door must stay closed; After the
entrance, the person will close the first door and, in
succession, will open the second closed door.
When a person is within the decontamination area the
infrared ray presence detector will switch off the UV-
FLOW, to protect personnel from UV irradiation; the
sensor will switch on the UV-FLOW again when the
person has left the area.
However, it is not required to switch off the UV-
FLOW if personnel wear UV-C ray protection
clothing, such as hats with visors, and stay within the
decontamination area only f o r the necessary time
of passage.

WARNING!!!
Follow carefully the instructions for both the HORIZONTAL and VERTICAL position because, although it is a device for
controlled radiation, it must be turned on by preventing reflected radiation to affect people. For example, reflections on
ceiling or walls surfaces may cause eye irritation and skin erythema.
In order to avoid accidental exposure to UV radiation, provide an accurate control of the context in which the device is
applied. Provide warning lights and / or pictograms to indicate the presence of such devices.
SCHEDULING
UV-FLOW can work 24/7 with no pause.

PROTECTIVE
GLASSES
Lamp maintenance is very important because UV-C light emitted by the source is not visible to the eye, so,
although you see the lamp ON, its germicidal effect may not be sufficient to performs disinfection treatment.
Before reaching the lamp, ALWAYS switch off power supply
If UV-C lamp gets dirty (or gets dusty) clean it with a clean cloth and alcohol, and avoid touching the glass part with
hands. To check UVC lamp life number of hours, correct product code of the spare UV lamp please refer to table 1.
The lamp, once it has reached the timing for replacement, must be replaced, this operation is carried out as follows:
• For each side of the device, unscrew one screw (or knob) which sets the screen and rotate it 90 degrees.
• Loosen the nuts of the holder and slide them along the lamp, grab the lamp from the 2 ends and pull it in a di-
rection parallel to the unit.
• Repeat steps in reverse to reassemble the new lamp again.
TROUBLESHOOTING
UV LAMPS
See MIANTENANCE
BALLAST
All UV models are supplied with electronic ballasts which guarantee an emission of 15% more if compared with traditional
ballasts. Furthermore, lamps are not influenced by environment temperature, (<-20°C). Finally, the switching on is
immediate, with no starter, and for this reason lamps last longer.
To preserve the original characteristics of IP sealing and insulation, in order to keep intact all the characteristics nece ssary
to ensure the long-lasting life of the product, the replacement of the electronic ballast must be carried out only by trained
personnel with requirements recognized by LIGHT PROGRESS; if necessary, you should return the product to the
company for repair.
Alternatively, you can purchase the entire power supply duct for substitution (for code see Table n.1).
