DEVICE DESCRIPTION
The series UV-DUCT-FL includes modules for disinfecting air in air conditioning systems(HVAC) with a reduction of
microbial load of 99.9%.
These modules consist of a box structure (flange) from which two UV lamps emerge, in the form of "U", protected by a
stainless-steel grid. They are generally applied along the ducts of air conditioning (pic. n.2).
The modularity of this device allows a straightforward application in all types of conduct, also in the final sectors of the
UTA (Air Handling Unit), with the ability to adapt to different needs and different sizes of ducts.
The main characteristics of UV-DUCT-FL, as the compact dimensions and device controls, allow a quick and easy in-
stallation, directly inside the air conditioning ducts.
APPLICATIONS AND RESULTS
The air conditioning systems involve numerous hygienic risks, even when filters are mounted, especially if they are not
absolute filters HEPA or ULPA type. The risks are mainly the following:
•• The possible formation of bacterial colonies on the surface of the heat exchangers, of the humidification panels,
filters (especially if they are subjected to regular maintenance). The bacteria can then be transported by the
flow of air and dispersed in the environment.
•• The possible formation of colonies of Legionella Pneumophila (Legionnaires' typhoid) due to the presence of
water in the humidification sections of the air handling unit (AHU).
Applied to the ventilation duct, UV-DUCT-FL reduces by 99.9% the airborne contamination, by means of an installa-
tion easy and safe for the personnel.
The apparatus allows for both the microbial blocking of access to the contamination controlled rooms (clean rooms;
microbes coming from outside or present in the recirculation air), both the block of cross-contamination, which may oc-
cur between two adjacent rooms, via the air conditioning ducts.
Scientific studies demonstrate the existence of a close relationship between air conditioning, airborne microorganisms
and human health. They confirm that there is a microbiological contamination carried by these plants causing various
diseases, such as:
1) Sick Building Syndrome, characterized by disturbances in the eyes and upper respiratory tracts (hyperactivity of
these mucous membranes) as well as nervous disorders (numbness, headache).
2) Legionellosis (Legionella Pneumophila - Legionnaires' typhoid). This pathology is frequently observed in environ-
ments with air conditioning systems. The Legionella infection can result in two distinct clinical pictures: Pontiac fever
and Legionnaires' disease. But it can also lead to the death of the infected person.
3) Tuberculosis (Mycobacterium Tub.) which is transmitted by air and enters the body through the respiratory route.
4) Humidifier disease or “Monday Fever”, characterized by an influenza-like symptoms that occur at the start-up of
humidification systems, and seem triggered by microorganisms able to proliferate in the ducts of air conditioning sys-
tems during the weekend shutdown of air.
OPERATION
The device works to direct radiation into the duct, resulting in substantial reductions of airborne microbes, with no con-
traindications. Thus, the indoor air will be not only conditioned, but also disinfected up to values of more than 99.9%.
The ongoing use of modules UV-DUCT (working 24 hours a day), regardless of the operation of the air conditioning
system, prevents the germs to move from one room to an adjacent one, through the conduct (blocking back). Our
technicians will calculate the configuration of the modules according to the following data:
•• Section of the ventilation channel.
•• Flow rate in m³ / h (or velocity).
•• Air temperature.
•• Relative humidity.
•• Microorganism reference to inactivate and percentage of destruction (usually E. coli, Mycobacterium t., Le-
gionella p. with destruction of 90% up to 99.99%).

BENEFITS AND ADVANTAGES
a) PHYSICAL ACTION AND ENVIRONMENTAL PROTECTION. Treatment by UV-C rays is purely physical, and
achieves always the same effect; also, there are no problems of overdose and rooms are always safe and practicable
(when devices are off). Rather, many methods of chemical treatment involve the use of dangerous products for the en-
vironment, and difficult to biodegrade, as well as the risk of contamination of foodstuffs. Also, by the use of chemicals it
is likely to develop resistant microbial forms with consequent danger to human health.
b) IMMEDIATE EFFECT. It takes just a very short time to obtain effective results (99% killing of the bacteria).
c) PRACTICABILITY AND SAVINGS. The treatment is immediate and ready for use. The maintenance is minimal with
low costs of both energy consumption and repairs.
c) ONGOING AND DEEP DISINFECTION
This system can always be turned on with no contraindications for people who have access to air conditioned rooms. It
therefore remains constantly below the level of the microbial environment and improve indoor air quality (IAQ), as pre-
scribed in the DL 81/2008 legislative act and recommended by the WHO (World Health Organization.
d) STOP TO CROSS CONTAMINATION
The contamination of an area may spread to other premises by the air conditioning system. The UV-C devices, to be
installed near the ridges of emission of air, prevent the spread of microorganisms.
e) FIGHT AGAINST THE DISEASE FROM AIR CONDITIONING
Any air conditioning system involves considerable hygiene risks if it is poorly engineered or if there is a lack of good
maintenance. Moisture(condensation) of filters and heat and adiabatic exchangers may become a receptacle for germs
and cause certain diseases such as:
Sick Building Syndrome (sick building syndrome), Legionellosis (Legionella P.; Typhoid Legionnaires'), Tuberculosis
(Mycobacterium t.), Etc..

ACCESSORY
LED + FAULTY LAMP ALARM
►UV-DUCT-FL …/…-LA
The LEDs on the lid indicate the correct operation of the lamps; if they are turned off, lamps are not working regularly.
(pic. 5).
In addition there is a pin on the left side (pic. 5), used for the remote signaling of lamp failure alarm. It is a free voltage
contact (two poles) that opens the circuit in case of failure (NC working lamp, max. 500mA - 24V).
If the devices to be installed are more than, you one can make a connection in series in order to have a single remote
fault alarm signal. By checking the turned off led, you will find out which lamp is faulty.
HOUR COUNTER
OPTIONALS
►UV-DUCT-FL …/…-H
The counter is placed on the left side of the unit.
The purpose of this accessory is to be able to display the working time of the lamps,
so as to allow the replacement once they have reached the 9,000 hours. The instru-
ment cannot be reset to prevent from counting accidentally losing.

MAINTENANCE
UV LAMP
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 reached the timing for replacement, must be replaced, this operation is carried out as follows:
1) Remove the locking screw placed on the lid of the box that contains the power supply.
2) Open the lid by turning it down.
3) Release the bulb from the lamp holder.
4) Remove the bulb from the box by sliding along the guide containment.
5) Repeat the above steps in reverse, to reassemble the lamp again.

POWER SUPPLY
All UV models are supplied with electronic ballasts which guarantee an emission of 15% more if compared with tradi-
tional ballasts. Furthermore lamps are not influenced by environment temperature that can goes until -20°C. Finally, the
switching-on is immediate, with no starter, and for this reason lamps last longer.
In case of failure, to replace the electronic power supply, first of all remove ALWAYS the device voltage, then proceed
as follows (PICS. 2 e 7):
1) Remove the locking screw placed on the lid of the box that contains the power supply.
2) Open the lid by turning it down.
3) Disconnect the wires on the right (4 or 7 wires) and the left (3 wires) placed on the power supply by pressing the
blade of a screwdriver on the slot corresponding to each input wire, to set it free. Pay attention to the succession of
links because each wire will have to re-occupy the same position at the end.
4) Remove the electronic ballast by the aid of a screwdriver.
5) Replace with a new ballast like the original (for code see Table n.1) and reconnect the wires paying attention to the
succession of steps.
6) Repeat the above steps in reverse.
LED + CIRCUIT BOARD
The LEDs on the lid indicate the correct operation of the lamps (pic. n.6). They are powered by an electronic card,
placed inside the box, which also triggers the remote signaling of the failure lamp alarm.
In case of failure, to replace the circuit
board or LED, first of all, ALWAYS remove
the device voltage, then proceed as follows
(pic. n.2 and n.7):
1) Remove the locking screw placed on the
lid of the box, that contains the power sup-
ply.
2) Open the lid by turning it down.
3) Disconnect the wires placed on the elec-
tronic card (three pairs with terminal AMP).
Pay attention to the succession of links
because each wire will have to re-occupy
the same position at the end.
4) Unscrew the screws holding the elec-
tronic card.
5) Replace with a new board like the origi-
nal (for code see Table n.1) and reconnect
the wires paying attention to the succes-
sion of steps.
6) Repeat the above steps in reverse.
