The germicidal UV lamp/charcoal-filter/pump unit
Always turn off the UV light before opening
the filter housing!!
What’s in this unit and how does it work?
This unit contains a layer of charcoal encased in a media bag for phase 1
cleaning, a germicidal low-voltage ultraviolet lamp for phase 2 disinfection
and a low-voltage pump to move the cleaned, disinfected water up to the
fountain’s spout by way of antimicrobial, silver embedded, tubing.
The media bag holds the carbon in place and eliminates
carbon dust building. Fill it with 1/4 cup of activated carbon. Rinse the
filled bag outside the housing (before
you put the bag in) and then slip it
in to the housing, folding the rest of the bag down on top. This
carbon-filled bag captures shed hair and debris and removes chlorine, foul
taste and odor from the water.
Now insert the UV light and then the pump as shown in the pictures below, making sure the cables go through the notch provided and screw the filter housing shut.
The low-voltage germicidal ultraviolet lamp produces
ultraviolet wavelengths that are lethal to microorganisms. The ultraviolet energy
emitted is at 365-369 nanometers. This wavelength is highly lethal to
virus, bacteria and mold spores. As a result, the microorganisms that pass
through the filter housing are deactivated, preventing them from
reproducing and rendering them harmless.
