If performing full maintenance on the inFlow™ ACE, set the collection head aside and continue to the next step in
. If maintenance is only being performed on the collection head, screw the piston onto the
insertion shaft, and then screw the collection head onto the outer shaft. Tighten the jam nut to lock the collection head
in place. For maximum sample volume, ensure that the bottom of the jam nut is flush with the bottom of the outer shaft.
21.
Connect a safety wire from the opening in the relief cap to the jam nut. Ensure that the safety wire is wrapped in a
counterclockwise rotation to prevent the associated threads from unscrewing from each other.
If a replacement safety wire is not available, ensure that the relief cap is securely tightened so that it can withstand the pressure
of the flowing stream.
