GENERAL
Duality - Mini UV is designed to fit and function in compact areas of
HVAC components. Germicidal ultraviolet (UVGI) helps inactivate
viruses and bacteria* on damp surfaces ensuring the optimal efficiency of your system.
Based on results from the testing of SARS CoV-2, MS2, Bacillus Thuringiensis,
*
Staphylococcus Epidermis, Aspergillus Niger, and Serratia Marcescens. See more

SAFETY INFORMATION
UV WARNING
High intensity ultraviolet light.
Exposure to direct LED UV light may be harmful.
Always protect eyes and skin from UV LEDs.
Never look directly into UV LEDs during operation.
Disconnect before servicing.
After installation, all UV light should remain internal within the
installed unit.
Ensure no UV light is visible from outside the installed unit.
LED lifespan can vary. For optimization, replace LEDs every 12
months.
ELECTRICAL WARNING

UV INSTALLATION NOTES
This device is typically mounted within mini split systems and
other limited space applications that are susceptible to the build
up of molds and bacteria.
For optimal VOC efficacy, mount the UV lights inside the supply
vent panel facing the blower wheel and ensure the UV light is
directed through the provided VOC filter.
For applications where VOC filters are not deemed necessary,
direct the UV light onto the rear side coils where moisture build up
is most prevalent.
Ensure the mounting of the UV strips do not direct light immediately out of the unit and into the living space.
