7. Use two wrenches to loosen the Swagelok connection between the jet
assembly and the heated transfer tube.
8. Carefully lift the detector module and jet assembly off of the transfer tube
and out of the GC. Be careful not to damage the fused silica gigabore liner.
When cleaning or replacing the jet, it is not necessary to disconnect any
plumbing, ignitor leads or the heater/sensor. Leave all attached and
disconnect the detector block from the transfer line at the Swagelok
fitting, then gently lift the block and rotate it enough to access the jet.
