Maintenance & Troubleshooting | 5-15
If the Oven/Sample System Enclosure is heated , close its door to
help maintain the temperature inside the enclosure while working
on the Cell.
In the next steps use a soft, non-abrasive cloth to place the Cell parts
on.
c. If the Measuring Cell has an Optical Bench/Cell Insulator, remove
the three screws that secure it to the Cell and remove the Insulator.
Use an o-ring removal tool to remove the outer o-ring from the
Cell. Take care not to scratch or damage the o-ring groove.
Carefully remove the Cell Window from the Cell by grasping it by
its outer edge and lifting it out of the Cell. Avoid touching the win-
dow surfaces. Set the Window aside on a soft, non-abrasive cloth.
Use an o-ring removal tool to remove the inner o-ring from the
Cell.
d. While holding the Cell vertically so that the Reflector Block end is
up, remove the three M4 x 20 mm screws that secure the Reflector
Block to the Cell. Remove the Reflector Block carefully to ensure
the Cell Window behind it does not drop out.
e. With the Reflector Block end up, carefully remove the o-rings and
Cell Window from the Cell.
Inspect the Windows for any chips, cracks, or scratches. If they are
not damaged, they can be cleaned and reused; set them aside on a
soft, nonabrasive cloth.
If the Windows are suitable for reuse, use Kimwipes
®
EX-L or an
equivalent extra low-lint tissue to clean the front and back sides. A
high purity solvent, such as Isopropanol (99 %), may also be used
(if suitable for use with the sample species). Rinse with pharma-
ceutical-grade distilled water.
Replace chipped, cracked, or scratched Windows when reassembling
the Cell.
f. Systems with a Cell RTD:
Note the position of the Cell RTD Clamp (see Cell RTD in Figure
5-1) and remove it from the Cell.
