Replacing The Laser - Thermo Scientific Omni FTIR Multi Gas CEMS Instruction Manual

Replacing the Laser

Thermo Fisher Scientific
Use the following procedure to replace the laser in the FTIR analyzer. The
laser is located behind the rear panel of the analyzer. The laser indicator
light on the analyzer front panel will be off if the laser has failed.
WARNING To avoid shock hazard, always turn off the FTIR circuit
breaker on the breaker panel before replacing any components inside the
FTIR analyzer. ▲
CAUTION High surface temperatures present. Allow sufficient time to
cool. ▲
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 A system operator can replace the laser, however it is
recommended that only our certified service engineers or on-site
maintenance personnel who have been trained by us replace the laser.
Whenever the analyzer compartment is open, there is a potential for
damage to sensitive components, which will affect the performance of the
system.

Equipment Required:
Phillips screwdriver
Hex wrench, 3/32-inch
Laser assembly
1. Shut down the FTIR analyzer and heaters by turning off the FTIR
circuit breaker and the Temperature Control circuit breaker on the
breaker box. Allow it to cool for 1 hour. This will put the system in fail
safe mode so that it will not be sampling stack gas.
2. The laser is located behind the rear panel of the analyzer, which can be
accessed from the rear of the system rack. To create space to work,
move the two short heated lines out of the way. If more room is
needed, use the 9/16-inch wrench to loosen the nuts to disconnect the
heated lines from the sample system heater assembly and/or the FTIR
