UV100E ULTRAVIOLET SYSTEM
3 69-1573—07
Surface Treatment System
When installed next to the cooling coil of your system, your Ultraviolet Surface Treatment System prevents a
high percentage of the growth of micro-organisms such as mold that may grow on duct surfaces, coils, and
drain pans. Individual results depend on careful installation and maintenance. See Fig. 2.
Your Ultraviolet Surface Treatment System operates a steady three-hours-on/
three-hours-off cycle. With Enviracom™ communication terminals hooked up,
your UV System turns off for the Winter 30 days after the last call for cooling occurs. And your UV System turns
on and resumes the on/off cycle with the first call for cooling in the Spring.
Fig. 2. Typical Surface Treatment System installations.
You can capture and minimize micro-organisms passing through your forced air system when you combine your
UV System with a high-efficiency air filtration system like an electronic air cleaner. Talk to your installer about
adding an electronic air cleaner to complement your UV System and provide added protection for you and your
family.
