Hazard Identification Information
Description
Ultraviolet C light bathes the moist surfaces on the coil and
drain pan, killing most microorganisms that can grow there.
Ultraviolet lights are typically installed on the leaving side of
the cool
ing coils in the unit. Each light module is mounted on a
rail and is removable for convenient bulb replacement.
UV Light Power Disconnect switches (
two per door) are fac-
tory installed on every door that allows a direct line of sight to
the
UV lamps when opened. These switches are designed to
prevent UV exposure when cabinet doors are opened and must
not be disabled.
A viewing window near the UV lights allows viewing to deter-
mine if the lights are energized. The v
iewing windows use spe-
cially designed glass that blocks harmful UV light.
