3. Remove the SPU oven lid by unscrewing the 4 hex stand-offs
circled below.
4. Remove the foam oven plugs by gently pulling them straight up
and out of their slots.
5. Disconnect the column transfer tubes from the column module
using a 1/4" open ended wrench on the hex nut and a 3/16" open
ended wrench on the column end hex union. Be sure to hold the
column end hex union firmly so it doesn't twist the column end
while loosening the nut.
Note: If your transfer tubes are fused silica and you're using
graphitized vespel ferrules, the ferrules can be re-used if
not badly deformed.
