Maintenance & Troubleshooting
9. With the new column module in hand, re-connect the module
power and communication cables.
10. Insert the column module between its mounting brackets and
press it about half way down into position.
Note: Inserting it half-way rather than all of the way allows for
easier re-connection of the transfer tubes.
11. Re-connect the transfer tubes to the column end fittings. If using
fused silica tubes, be sure to insert the fused silica into the fitting
until you "feel" it stop against the bottom of the fitting. Tighten
the hex nut with the 1/4" wrench while holding the column hex
union with a 3/16" wrench until snug. Do not over tighten.
