ULTRAVIOLET SYSTEM
69-1859EFS—01 2
IMPORTANT
Please read these instructions and keep them in your records.
HOW YOUR ULTRAVIOLET AIR TREATMENT SYSTEM OR SURFACE TREATMENT
SYSTEM WORKS
Depending on installation, your Ultraviolet System can operate as an Air Treatment System or as a Surface Treatment System.
Air Treatment System
Installed in the return air duct of your system, your Ultraviolet
Air Treatment System kills a high percentage of airborne
germs circulating through your forced air heating and cooling
system. Individual results depend on careful installation and
maintenance and on the actual amount of time your system
fan operates. See Fig. 1.
Fig. 1. Typical Air Treatment System installations.
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.
