Setting the Insertion Length
12. Prior to installing the inFlow™ ACE, the length the insertion shaft will need to travel inside the pipeline must be determ-
ined. Measure the distance the insertion shaft must travel from the top of the pipeline isolation valve to the desired
insertion depth (e.g., the center one-third (¹⁄₃) of the pipeline) ( Figure 11 ). This will be the shaft insertion length.
Figure 11: Determining the Insertion Depth
13. Pull up on the insertion shaft to ensure that it is fully retracted. The end of the collection head should be flush with or in
close proximity to the flange face ( Figure 12 ).
14. Beginning at the top edge of the lockdown studs, measure along the insertion shaft to the desired insertion length
( Figure 12 ). As needed, use a felt tip pen to mark this point.
