5
Turn off (where applicable): the FID flame, FPD flame, and
TCD filament.
6 Cool the detector.
7 Connect the appropriate adapter to the detector exhaust.
A rubber adapter tube attaches directly to a uECD, or TCD
exhaust vent.
A separate adapter (19301-60660) is supplied for the FID.
Insert the adapter into the detector exhaust vent as far as
possible. You will feel resistance as the adapter O-ring is
forced into the detector exhaust vent. Twist and push the
adapter during insertion to ensure a good seal.
Flowmeter tube diameters vary by model; modify the adapter to the
flowmeter tubing as needed.
