10. Connect the laser power supply cable to the power distribution cable.
11. Re-install the analyzer rear panel. Be careful to place all internal cables
completely inside the analyzer to avoid damaging them, and then line
up the mounting holes. Install the mounting screws using the 3/32-
inch hex wrench, taking care to support the panel until the screws are
in place. Tighten until snug.
12. Re-connect the purge air line to the right side fitting labeled "Purge In"
on the bottom rear of the analyzer. Press the fitting in until it clicks
into place.
13. If they were previously removed, use the 9/16-inch wrench to re-
connect the two short heated lines to their original positions on the
sample system heater assembly and the FTIR analyzer. Tighten until
snug.
14. Power up the FTIR analyzer and heaters by turning on the FTIR
circuit breaker and the Temperature Control circuit breaker on the
breaker box.
15. If the new laser is working properly, the laser indicator light on the
analyzer front panel will be on. Wait 15 minutes for the new
components to stabilize thermally and then align the analyzer by
following the instructions in Chapter 3. (See "OMNIC" software on
page 3-11.)
Use the following procedure to replace the detector in the FTIR analyzer.
The detector is located behind the front panel of the analyzer.

WARNING To avoid shock hazard, always turn off the FTIR circuit
breaker on the breaker panel before replacing any components inside the
FTIR analyzer.
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.
