Installation Guide: TCD-to-FID Series Connection
1
Carefully remove the preformed thermal insulation from
around the detector block to expose two screws securing the
block to the oven top. Remove the screws.
2
Carefully lift the block just enough to expose the vent tube
support retaining screw.

Carefully slide the heater/sensor and Delta PRT sensor
cartridges out of the block. Sensors (the small cartridges)
must be handled carefully to avoid breakage.
Adjusting Vent Tubing and Reinstalling the TCD Block
1
Once the TCD block is removed from the oven enough to
expose the screw securing the vent tube support, or before a
new TCD block is installed into the top of the oven, remove
the retaining screw securing the vent tube support and
remove the support.
2
Carefully bend the vent tube downwards to be alongside the
detector column / make up gas fitting. Align the tube so it fits
into the small slot provided in the oven liner. Reinstall vent
tube support with reversed orientation.
3
If installing a new TCD, continue with instructions in the
TCD installation document through all wiring connections.
When finished, continue with instructions below,
