b. If the bottom surface is rough or engraved, or a groove on the
side of the mirror is detected, a stainless steel mirror is being
used.
2. Refer to "To clean the mirrors" below for the procedure to clean

1. Power down the analyzer following the procedure outlined under “To
power down the analyzer” in the Firmware Manual.
2. Isolate the analyzer from the sample bypass flow.
3. If possible, purge the system with nitrogen for 10 minutes.
4. Carefully mark the orientation of the mirror assembly on the cell
body.
5. Gently remove the mirror assembly from the cell by removing the 4
(28 m or 8 m measurement cell) or 6 (0.1 m or 0.8 m measurement
cell) socket-head cap screws and set on a clean, stable and flat
surface.
Do not attempt to replace a glass mirror with a stainless steel
mirror or system calibration may be adversely affected.
The sample cell assembly contains a low-power, 10 mW MAX, CW
Class 3b invisible laser with a wavelength between 750 to
3000 nm. Never open the sample cell flanges or the optical
assembly unless the power is turned off.
All valves, regulators, switches, etc. should be operated in
accordance with site lock-out/tag-out procedures.
Process samples may contain hazardous material in potentially
flammable and/or toxic concentrations. Personnel should have a
thorough knowledge and understanding of the physical properties
and safety precautions for the sample contents before operating
the SCS.
Careful marking of the mirror orientation is critical to restoring
system performance upon reassembly after cleaning.
