28 F300S/F300SQ Ultraviolet Lamp System
Ozone
The Fusion UV Lamp System makes less ozone than a conventional arc lamp. For
example, a pair of lamps running for twelve hours in a non-vented room resulted in a
steady state concentration of less than 0.02 parts per million. This was a level that
could barely be detected by odor and a factor of five below the level of 0.1 parts per
million allowable for continuous exposure (American Conference of Governmental
Hygienists).
All Fusion UV Lamp Systems should be exhausted to the outdoors.
Temperature
Handle the bulb with cotton or surgical gloves or a lint-free towel at all times, as
fingerprints can be etched into the quartz.
Ozone is a gaseous form of oxygen which is formed by ultraviolet light. It
has a characteristic pungent odor to which most people are quite sensitive
(people can typically detect concentrations of several parts per hundred
million). At high concentrations it can cause discomfort or at sufficiently
high levels be dangerous.
Surface temperatures of the lamp during normal operation may
exceed 120
o
F. Metal components near the lamp will also be hot.
Before attempting service procedures on the lamp, allow the unit
to operate in STANDBY so that the blower continues to run. The
bulb will cool completely in less than one minute. If the blower
is not allowed to run, the bulb will retain heat for several
minutes. Observe appropriate precautions to avoid burns.
