KF202 UV-C LIGHT SANITIZER

User Manual

PLEASE READ ALL INSTRUCTIONS

BEFORE USING THIS SANITIZER

Thank you for purchasing our UV-C Light Sanitizer, one of the
most advanced bacteria-reducing tools in the world. The UV-C
Light Sanitizer can help you and your family to significantly
reduce infectious microorganisms and germs such as fungus,
mold, bacteria and viruses from your home, office or travel
environment. By following these instructions and safeguards,
you and your family will benefit from the use of your UV-C Light
Sanitizer for many years to come.

The UV stands for Ultra-Violet light. Ultraviolet light represents the
frequency of light between 100 nanometers (nm) and 400nm and
cannot be seen with the naked eye. Within the UV spectrum lie
three distinct bands of light: UV-A, UV-B, and UV-C.

• UV-A (400-315nm) The long wave UV light (315nm to 400nm)
or UV-A refers, to what is commonly called “black light.” This is
the longest wavelength region and lowest energy; it represents
the largest portion of natural UV.

• UV-B (315-280nm) The UV-B (280nm to 315nm), or midrange
UV, causes sunburn.

• UV-C (280-100mm) The Germicidal UV Light (100nm to 280nm),
or UV-C, is effective in microbial control.

The most effective frequency for microbial destruction is between
280nm and 200nm within this UV-C band. Therefore, as long as
the nm frequency of Germicidal lamps have been well-controlled
within the range, then the microbial will be significantly reduced.

Opportunities for infection are abundant and virtually everywhere,
so it is important to realize that use of the UV-C Light Sanitizer
does not guarantee that the user will avoid illness. To avoid
microbial infection, one must take a wide range of precautions.
Use of the UV-C Light Sanitizer is an important precaution, but not
the only precaution that one should take.
