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?

 

inside of a pet drinking fountain with UV sanitizer

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.

 

flashing the Bio filter media bag

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.

UV-lamp warningThe 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.
