breaker on the breaker panel before replacing any components inside the
FTIR analyzer.
CAUTION The source element becomes extremely hot during normal
analyzer operation. Always turn off the analyzer and allow the elements to
cool for at least 15 minutes before removing the source from the analyzer.
Handle the source assembly only by the ceramic base.
Equipment Damage Some internal components can be damaged by small
amounts of static electricity. A properly grounded antistatic wrist strap
must be worn while handling any internal components.
Important Note The FTIR analyzer source is pinned in place and pre-
aligned. Replacing the source should not affect measurement results,
however, an improperly installed or handled source will affect the
performance of the system. A system operator can replace the source,
however, it is recommended that only our certified service engineers or on-
site maintenance personnel who have been trained by us replace the
source. ▲
