b. Keeping the module flap cover open, place the module in its seat. Be sure to insert the
25-pin male connector, on the bottom of the module, into the 25-pin female
connector on the detector seat of the detector housing.
c. Use a T20 Torxhead screwdriver to tighten the three captive fixing screws without
overtightening.
.
d. Close the module flap cover.
9. Remove the plug and connect the analytical column end to the detector.
a. Position the column so that the end of the column extends the proper distance above
the end of the ferrule as reported in
Table 17 .
10. Open the gas supplies.
11. Check the gas supply for leaks.
a. Use a handheld electronic leak detector (Thermo Scientific GLD Pro leak detector or
equivalent) to check each fitting for leaks.
b. If you detect a leak, tighten the connection and retest it.
ATTENTION To maintain the correct alignment the screws must be tightened in turn.
Tighten each screw only a small amount before moving to the next screw. Repeat until all
are secure.

Note If you are installing an In-Series Connection TCD module (TCD module
modified for the connection in-series with a second detector or with a
methanizer), you must connect the vent line metal tubing, that protrudes into
the GC oven, to a
FID
second detector proceeding as follows:
• Being careful not to create too narrow angles, bend the vent line metal
tubing until its end reaches the bottom of the second detector.
• Making sure that the end
of the vent line metal tube is perfectly straight
, insert it
like as an analytical column through the proper detector retaining nut and
ferrule.
ATTENTION If you are connecting the In-Series Connection TCD module to a
FID , NPD , or FPD , position the vent line metal tubing so that the end of the
tubing extends the proper distance above the end of the ferrule as reported in
Table 17 .
If you are connecting the In-Series Connection TCD module to an ECD , the
insertion depth of vent line metal tubing must be 21 mm .
