IMPORTANT INSTRUCTIONS

FOR SAFE USE
WARNING BEFORE USING UV-C STERILON FLOW FOR THE FIRST TIME, READ THE USER MANUAL AND FOLLOW THE INSTRUCTIONS.

The UV-C STERILON lamp is for disinfection only. The UV-C STERILON lamp should not be used to illuminate rooms.

• After starting the UV-C STERILON FLOW lamp (direct disinfeciotn), you cannot stay in the room where the lamp is on.
  Wear protective glasses, long-sleeved clothing and protective gloves when turning it on / off.
  Avoid contact with the light source. UV-C light is harmful to the eyes and skin.

• The room with the lamp turned on (in direct disinfection mode) must be protected against access by other people. The UV-C STERILON FLOW lamp may only be operated by adults.

UV-C STERILON FLOW SAFETY INSTRUCTIONS

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 effectiveness of disinfection. Remember that the disinfection efficiency 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 effectiveness 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 m2

9. The smell emitted by the UV-C STERILON FLOW is a technical fragrance. It can last for approximately ¹⁴⁰ hours of device use. This smell does not pose a threat to the users of the device.

10. A small amount of visible blue light – which is a reflected light, does not contain UV-C radiation and is safe for humans.

Disinfection efficiency
Depending on the lamp power, the flow is:

• For the power 72 W – 160 m /h
• For the power 144 W – 200 m3/h

In ECO mode, the air flow is reduced to 110 m3/h, which results in quieter operation. Please note that the lamp in ECO mode must be active for at least two hours longer in order to be sufficiently effective.

The maximum volume (cubature) of the disinfected room:

• for luminaires with a power of 72 W – 75 m
• for luminaires with a power of 144 W – 120 m

Maintenance and filter replacement
Sterilon Flow UVC luminaires are standard equipped with PPI30 filters located in the fan housing. This filter should be checked after 4 months of the device operation. In case of dirt that could block the air flow (e.g. when the device is operated in dusty rooms), the filter should be replaced or cleaned under running water after every 4 months of operation. If the filter is not dirty during the first inspection, its cleanliness should be checked after every 6 months (or 1000 hours) of operation of the device and replaced or cleaned under running water if dirt appears. The filter should be removed from the pressed-in (clicked-in) housing on the fan, replaced and the housing pressed back in. The UV-C Sterilon luminaire is HEPA filter compatible. HEPA filters can be installed interchangeably with dust filters.

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 UV-C STERILON FLOW 72W PREMIUM – INSTALLATION INSTRUCTION

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.
• Secure the room with the turned on luminaire against other people’s access.
• When carrying out activities related to the operation of the UV-C STERILON FLOW lamp, special protective glasses and gloves as well as wearing long-sleeved clothing are recommended (only with direct disinfection).

Disinfection efficiency
Disinfection efficiency 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:

• 2,4 W/m² – UV-C radiation (UV-C STERILON FLOW 72 W)
• 4,8 W/m² – UV-C radiation (UV-C STERILON FLOW 144 W)

The irradiation area for direct disinfection from a distance of 1 m is:

• 72 W – 7 m²
• 144 W (one direction) – 7 m²
• 144 W (two direction) – 2 x 7 m²

The effciency 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 effective the light will be. The approximate time for surface disinfection by UV-C STERILON luminaires is 15 minutes. However, this time may dier 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:

• Set the lamp so that the light falls on the surface to be disinfected.
• 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.
• After turning the luminaire on, you cannot stay in the room. When turning it on/off, use protective glasses and wear long-sleeved clothing and gloves.
• Approximate exposure time is 15 min.
• Note that very long exposure to the UV-C lamp can degrade some elements within its range, e.g. plastics.
• We recommend ventilating the room every 4 operating hours of the device.
• We recommend using the product in rooms with unobstructed ventilation.
• Do not use in rooms smaller than 6 m

Disinfection effectiveness of SARS-CoV-2 (coronavirus causing Covid 19)
There are no published offcial 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 almost 7 mJ/cm . Based on this, the dose needed to neutralise the coronavirus, which causes the  COVID-19 disease is estimated 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.
