4. Replace the window retaining nut (11). Tighten to 14 inch-
pounds. To avoid possible damage to the windows, do not
exceed 14 inch-pounds of torque.
5. Repeat steps 1 through 4 for the other side of the flow cell.
6. If the cell tubing was removed, re-install as follows:
•
Replace the cell inlet tubing by replacing its fitting into
the inlet hole (the one next to the hole for the heat
exchanger restraint).
•
Bend the tubing around the cell so that it circumscribes
the cell body in the heat exchanger groove before it
approaches the hole for the heat exchanger restraint.
•
To improve heat exchange between the inlet tubing and
flow cell body, a heat conductive epoxy should be
applied into the groove before the tubing is installed.
•
After the epoxy has been applied, secure the tubing into
the heat exchanger groove by replacing the heat
exchanger restraining screw (5) and washer (4).
•
Replace the cell outlet tubing by placing its fitting into the
outlet tubing hole.
7. Reinstall the flow cell body on the flow cell holder using the
two mounting screws. Insure that the protruding nose piece
of the flow cell is inserted into the cell mount.
8. Reinstall the flow cell onto the detector as outlined in the
installation section of this manual.
