Ultraviolet (UV) 
Germicidal 
Irradiation Lights 
(optional)

The United States Environmental 
Protection Agency (EPA) believes 
that molds and bacteria inside 
buildings have the potential to cause 
health problems in sensitive 
individuals. If specified, Trane 
provides ultraviolet lights (UV-C) as 
a factory-engineered and installed 
option in select commercial air 
handling products for the purpose of 
reducing microbiological growth 
(mold and bacteria) within the 
equipment. When factory provided, 
polymer materials that are 
susceptible to deterioration by the 
UV-C light will be substituted or 
shielded from direct exposure to the 
light. In addition, UV-C radiation can 
damage human tissue, namely eyes 
and skin. To reduce the potential for 
inadvertent exposure to the lights by 
operating and maintenance 
personnel, electrical interlocks that 
automatically disconnect power to 
the lights are provided at all unit 
entry points to equipment where 
lights are located. 

 

WARNING

Equipment Damage From 
Ultraviolet (UV) Lights!

Trane does not recommend field 
installation of ultraviolet lights in its 
air handling equipment for the 
intended purpose of improving 
indoor air quality. High intensity C-
band ultraviolet light is known to 
severely damage polymer (plastic) 
materials and poses a personal 
safety risk to anyone exposed to the 
light without proper personal 
protective equipment (could cause 
damage to eyes and skin). Polymer 
materials commonly found in HVAC 
equipment that may be susceptible 
include insulation on electrical 
wiring, fan belts, thermal insulation, 
various fasteners and bushings. 
Degradation of these materials can 
result in serious damage to the 
equipment. 

Trane accepts no responsibility for 
the performance or operation of our 
air handling equipment in which 
ultraviolet devices were installed 
outside of the Trane factory.
