DEVICE DESCRIPTION
UV-DIRECT ....H-NX series includes a UV-C lamp lodged inside a shaped case of small size, entirely made of stain-
less steel and with polished aluminum screen, to increase performance also reflecting the proportion of UV-C which
should be dispersed in the direction opposite to that useful. The UV-C lamps, with emission peak at 235.7nm.
(nanometers), have a strong germicidal power against all organisms (fungi, bacteria and viruses).
The shaped case consists of a box of stainless steel AISI 304, within which a watertight Aluminum channel is located
containing all the electronic power supply, with degree of protection IP 55.
The UV-C lamp can also be protected by a grid of stainless steel AISI 304 (option). The unit comes complete with a
cable 3x1 mm, without plug for power supply.
OPERATION
The UV-DIRECT series can be installed in any type of environment to obtain deep disinfection of air and surfaces, even
those that are difficult to reach with traditional cleaning systems. When the lamp is ON there is a strong reduction of
microbes present in the ambient air and on the surfaces reached by UV rays. For example, 8 mins. at a distance of 3m
from the device, there is a 99% reduction of bacteria Bacillus, Coli, Clostridium, Legionella, Vibrio, Salmonella,
Pseudomonas, Staphylococcus, Streptococcus, etc.
Thanks to the natural circulation of the air, even the microbes located in hidden areas are continuously pulled toward
the area of the U.V. rays so that their overall level decreases progressively.
Use is allowed when there is no personnel present or if contained within adequately screened areas. The device must
be switched on for 2 ± 3 hours during the hours of work breaks; for example, by means of a programming clock, night
operation can be managed in the hours immediately prior to the entry of the operators, to allow entry in a freshly
disinfected site. Operation can also be managed by means of appropriate power units that, especially in case of
installation of various devices, can manage other operations, such as:
• Power timing; it is possible to regulate the duration of treatment by means of a regulatable timer.
• Managing entries; a security system turns out the lights in case of entry of staff.
• Remote and local alarms in case one or more lamps switch off, due to wear, a spy light will light up on the front
panel and it will be possible to use a contact to signal the failure remotely.
• Counter to manage the proper replacement of lamps.
BENEFITS AND ADVANTAGES
DEEP AND CONTINUOUS DISINFECTION
This device can be switched on continuously without people being present (i.e. during the night for 2-3 hours). The dis-
infection of the air, the machinery, and everything that is contained inside the room allows beginning the work day in
ideal hygienic conditions. In this way, the level of microbial load in one site is maintained constantly low.
PHYSICAL ACTION AND ECOLOGICAL PROTECTION
Treatment with UV-C rays is purely physical, always allowing treatment with the same efficiency; there is no danger of
overdosing with UV rays in the air. In contrast, many chemical treatment methods involve the use of products that are
risky and difficult to biodegrade, with consequent hazards to human health; besides, the use of chemical products, in
contrast to UV-C rays, could develop resistant microbial forms.
PRACTICALITY AND ECONOMY
Treatment is immediate and ready to use. Maintenance is minimal with low costs of both energy consumption and of
maintenance.
IMMEDIATE EFFECT
Effective treatment (99.9% bacteria reduction) takes just a few minutes.
NO CHEMICAL/PHYSICAL CHANGES
Treatment is cold and dry; it causes no organoleptic or qualitative changes in the food.
NO DANGER OF DISPERSION OF GLASS
With the special UVLON® protection, there is no danger of dispersion of glass fragments resulting from any breakage
of UV-C lamps.

INSTALLATION
In the case of application of UV-DIRECT for direct irradiation of the environment, the device should be positioned on
the ceiling almost in central position. The installation of several units should be carried out so as to distribute them
un iformly in the environment (to avoid the hidden areas, such as the corners; it should allow all the air to be treated).
These models can be mounted on the wall and still comply with the regular distribution (Fig. 2).
The area/space covered by the UV DIRECT devices is shown in Table 1. The final result of the disinfection will still be
made dependent on the amount of germs coming in from the external environment.

MAINTENANCE
UV LAMP
USE
PROTECTIVE
GLOVES
WEAR
PROTECTIVE
GLASSES
Lamp maintenance is very important because the 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
perform disinfection treatment.
Before reaching the lamp, ALWAYS switch off at the power supply.
If the UV-C lamp gets dirty (or dusty) clean it with a clean cloth and
alcohol. Avoid touching the glass part with hands. To check UVC lamp
life (number of hours), of the spare UV lamp please refer to table
1(correct product code required). The lamp, once it has reached the
timing for replacement, must be replaced, this operation is carried out
as follows:
• Loosen the nuts on the lamp housing and let them slide along
the lamp; grab the lamp at the 2 ends and pull it in a direction
parallel to the lamp.
• Repeat the steps in reverse to insert the new lamp
.
TROUBLESHOOTING
UV LAMP
See MAINTENANCE.
BALLAST
All UV-FLOW models are supplied with electronic ballasts which guarantees 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. For this reason, lamps last longer.
To preserve the original features of original IP protection and isolation class, and to maintain all the characteristics that
guarantee the lasting of this product, the ballast replacement must be done by qualified technicians verified by Light
Progress. In case of necessity, please, send the device back to our facility for any kind of repairs.
If this is not possible you can order the entire supply channel for replacement (for code see Table 1).
