•
Warning: Plants and/or materials that are exposed to higher dosages of UV-C may become damaged
and/or discolored.
Warning: Ensure plants are not exposed to UV-C radiation
•
Lamps include Mercury. If a lamp breaks, ventilate the room for 30 minutes and remove the parts,
•
preferably with gloves. Put them in a sealed plastic bag and take it to your local waste facilities for
recycling. Do not use a vacuum cleaner. Please follow User Manual.
•
The luminaire shall be installed by a qualified electrician and wired in accordance with the latest IEE
electrical regulations or the national requirements.
•
During installation or when maintaining the luminaire use static free gloves to avoid marks on the
luminaire.
To remove dirt and spots use the following:
•
-
Dust: only use microfiber cloths.
-
Fingerprints, etc.: use a cleaner for synthetic materials with antistatic properties.

UV-C basic information
What is UV-C?
Ultraviolet (UV) light is invisible to human eyes. It can be subdivided into three categories:
•
UV-C from 200 to 280 nm - For disinfection purposes and germicidal application.
UV-B from 280 to 315 nm - For medical use (i.e. phototherapy to treat skin conditions, including psoriasis).
•
UV-A from 315 to 400 nm - For use with curing, suntanning and insect traps.
•
How does UV-C work?
•
UV-C radiation can break the DNA and RNA of bacteria, viruses and spores, meaning that they leave them harmless. There are
no known micro-organisms resistant to UVC.
•
UV-C technology has been used safely and effectively in hospitals and governmental buildings for more than 40 years.
Most UV-C solutions utilize conventional lighting, with LED now improving in efficiency.
•
•
The peak output of our germicidal lamps (253.7nm) is close (80-85%) to the maximum effectiveness of UV-C (265nm).
•
Smaller UV-C wavelengths (222nm) are being explored as less harmful alternatives.

Maintenance and safe use
a)
Never operate luminaire when any living creature is in the room.
b)
Never look into a source of UV-C.
c)
Useful life – Luminaire is equipped with UV-C source (TUV lamp) which has specified useful lifetime of 9000h securing
minimum 90% of initial irradiance level. Always replace lamp before reaching 9000h. Lamp will work electrically much longer,
but radiated amount of UV-C after 9000h may be less than in specification causing reduction of disinfection capability.
Mounting timer can support monitoring of lamp lifetime.
d)
Be aware dust can reduce disinfection efficiency. Remove regularly dust from lamps with use of dry cloth. Remove dust from
surfaces you are going to disinfect to increase disinfection efficiency.
e)
Replace lamp carefully once it reaches 9000h. Lamp contains Mercury (Hg) which is hazardous to human.
