6. TERMS OF USE
Normal operating conditions:
•
ambient temperature from +10
°
C to +35
°
C
•
relative humidity up to 85% (non- condensing)
•
approximate room size up to 16-18 square meters.
7. STORAGE AND TRANSPORTATION
The device should be stored in its original packaging in a dry and cool (from -30
°
C to +50
°
C)
place, away from exposure to moisture, heat sources and direct sunlight. Storage without
original packaging is allowed indoors at ambient temperature from +5
°
C to +40
°
C and relative
residual humidity not exceeding 80%. After storage, the device should be unpacked at an
ambient temperature of +5
°
C to +40
°
C and relative residual humidity not more than 85%.
The product should be transported in covered vehicles, taking care to protect the package
contents from excessive shocks and bumps.
Dropping or throwing the device is not permitted as it may result in fracturing and breaking of
the glass filtering element and UV lamps, leading to the device losing its effectiveness as well as
loss of warranty.
8. PRINCIPLE OF OPERATION
Operation of the device is based on photocatalytic
oxidation of organic impurities on a porous glass surface
nanocoated with crystalline titanium dioxide (the PC-
element). Photocatalysis occurs under long-range soft
UV radiation (~365nm). Natural convection occurring
inside the device due to heat from UV lamps (see. Fig.2)
draws cooler air into the device through vents at the
bottom at a rate of about 25 cubic meters (about 883
cubic feet) per hour. Organic particulate (airborne
volatile organic compounds, bacteria and viruses) greater
than 10nm is adsorbed on the surface of the PC-element,
where it is subsequently mineralized by UV radiation
primarily into trace amounts of carbon dioxide and water
vapor.
The PC-element is made of a proprietary inert porous
glass material; it is unaffected by UV radiation and the
process of photocatalysis. Under normal use conditions
the PC-element does not require any maintenance and
has an unlimited life span.

No ozone is produced during operation
of this device. UV radiation in the 315-
400 nm wavelength range is absolutely
harmless to humans, animals and
plants.
