UV-C STERILON FLOW SAFETY INSTRUCTIONS
EN
FLOW VERSION
UVC flow luminaires use ultraviolet light, destroy the DNA or RNA of all microorganisms that will be exposed and remove viruses,
bacteria and fungi from the air. Covered UVC light does not reach the outside of the lamp. Thanks to stimulated circulation, the air
passes through luminaire interior, where it is exposed to the light and cleaned, and then pushed outside. UV-C STERILON FLOW
luminaires may work in the presence of people.
Exposure method:
1. Place the lamp in a disinfected room, if possible in a central place, to increase the e ectiveness of disinfection. Remember that
the disinfection e ciency in a given place decreases as the distance from the lamp increases.
2. Do not cover the luminaire fan, do not place any objects on the luminaire. In order not to disturb circulation, leave an empty
space and do not put any objects within 1m of the luminaire fan.
3. There may be people in the room. They can move freely and do not need protective clothing.
4. Do not open the luminaire covers during its operation. Secure the luminaire against uncontrolled opening by other people,
especially pay attention to children.
5. Do not open the window while the luminaire is operating, as this will reduce the e ectiveness of disinfection.
6. We recommend ventilating the room every 4 operating hours of the device.
7. We recommend using the product in rooms with unobstructed ventilation.

8. Do not use in rooms smaller than 6 m
Disinfection e ciency
Depending on the lamp power, the flow is:
3
For the power 72 W – 110 m /h
ź
3
For the power 144 W – 160 m /h
ź
The maximum volume (cubature) of the disinfected room:
3
for luminaires with a power of 72 W - 50 m
ź
for luminaires with a power of 144 W - 75 m
ź
Maintenance and filter replacement
UVC - Sterilon Flow luminaires are standard equipped with PPI30 foam filters. This filter should be cleaned under running water
or replaced after every 80 hours of luminaire operation. The filter should be removed from the push-in (click-on) housing on the
fan, replaced and the housing pressed back on. The Sterilon UV-C lamp is designed for mounting a HEPA filter. The HEPA filter can
be mounted additionally or interchangeably with a regular filter.
DIRECT DISINFECTION
Operational safety
The UV-C light emitted by the lamp is highly harmful to humans and other living organisms, damages eyesight, skin and cell DNA.
UV-C light degrades the DNA and RNA code in the cells of living organisms. After starting the luminaire no people or animals
should be within the range of direct UVC rays.
Damage to the luminaire will not a ect your health while maintaining basic precautions. If the fluorescent lamps break, ventilate
the room for 30 minutes and remove the contaminated parts, preferably with gloves. Place them in a sealed plastic bag and take
to a local waste disposal facility for recycling. Do not use a vacuum cleaner to remove damaged parts.
In particular, you should:
Never look directly at the turned on UV-C STERILON FLOW luminaire or stay within the reach of UV-C rays.
ź
Secure the room with the turned on luminaire against other people's access.
ź
When carrying out activities related to the operation of the UV-C STERILON FLOW lamp, special protective glasses and
ź
gloves as well as wearing long-sleeved clothing are recommended.

Disinfection e ciency
Disinfection e ciency is presented by CIE and other research units based on the dose of energy needed to remove 90% of
microorganisms from the surface. For most of the known bacteria and viruses the required dose does not exceed 8 mJ / cm . This
means that the lamp emitting 1 W of UV-C radiation at a distance of 1 metre from the given surface needs 80 seconds to disinfect
it in 90%.
Lamps from the Sterilon series emit light at a distance of 1 metre from the source:
2
2,4 W/m - UV-C radiation (UV-C STERILON FLOW 72 W)
ź
2
4,8 W/m - UV-C radiation (UV-C STERILON FLOW 144 W)
ź
The irradiation area for direct disinfection from a distance of 1 m is:
2
72 W - 7 m
ź
2
144 W (one direction) - 7 m
ź
2
ź 144 W (two direction) - 2 x 7 m
The e ciency of UV-C radiation decreases in inverse proportion to the square of the distance from the light source. Therefore, the
closer we place the light source to the surface requiring disinfection, the more e ective the light will be. The approximate time for
surface disinfection by UV-C STERILON luminaires is 15 minutes. However, this time may di er from the above as it depends on
the power of the lamp used and the distance of the disinfected surface from the light source. This time also depends on the
ambient temperature and humidity.
Exposure method:
ź Set the lamp so that the light falls on the surface to be disinfected.
ź The UV-C light source should be positioned as close as possible to the surface to be disinfected, and also, so that the scope of
covers the largest part of it. Objects placed in the shade, where the UV-C rays cannot reach, will not be disinfected.
Open the luminaire covers before turning it on.
ź
After turning the luminaire on, you cannot stay in the room. When turning it on/o , use protective glasses and wear long-
ź
sleeved clothing and gloves.
Approximate exposure time is 15 min.
ź
Note that very long exposure to the UV-C lamp can degrade some elements within its range, e.g. plastics.
ź
We recommend ventilating the room every 4 operating hours of the device.
ź
ź We recommend using the product in rooms with unobstructed ventilation.

ź Do not use in rooms smaller than 6 m
Disinfection e ectiveness of SARS-CoV-2 (coronavirus causing Covid 19)
There are no published o cial studies confirming the dose of energy that is needed to neutralize the virus that causes COVID-19
disease. However, its structure is compared to the "Hepatiti A Virus" virus more resistant to UV-C rays, for which the dose is
2
almost 7 mJ/cm . Based on this, the dose needed to neutralise the coronavirus, which causes the COVID-19 disease is estimated
2
to be approximately 4 mJ / cm . This means that the lamp emitting 1 W of UV-C radiation at a distance of 1 metre from the surface
needs 40 seconds to disnfect 90% of the surface from the virus.
