Gas Cell Mirror Configuration
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
It is recommended that only our certified service engineers
align the mirrors in the gas cell. There is a potential for damage to sensitive
components or improper alignment, which will affect the performance of
the system.

1.
Be sure that the FTIR heaters are still off from the “
Replacing the Gas
Cell
” procedure, that is, the Temperature Control circuit breaker on
the breaker box is off.
2.
Using the 5/32-inch hex wrench, remove the 2 screws near the fitting
plate only, that mount the gas cell to the mounting plate.
3.
Using the Phillips screwdriver, remove the 20 screws that mount the
cover on the coupling optics (relay mirror compartments), and then
remove the cover (
Figure 5–34
). Do not remove the 2 screws on the
front that are further away from the edge than the other screws.
4.
Using the 5/32-inch hex wrench, remove the 4 screws that mount the
nickel plated aluminum cell to the plate. Carefully remove the gas cell
casing, leaving the mirrors in place (
Figure 5–33
).
