2.  Installing a Column

Slide the column heater up.

Slide the column heater up
on its aluminum slider.

Secure one nut to the column.

Install the column of your choice using the included PEEK finger tight nuts. Slide the
nuts onto the PEEK tubing, letting about 1mm of PEEK tubing protrude.

Slide the column through the column heater so you can reach the other end,
and attach the second nut.  Roughly center the column in the column heater.

Replace the black column heater end caps, which have notches in them for the PEEK tubing.  Pack in any
loose insulation. When you have replaced both end caps as shown below, slide the column heater back down
into the operating position.
