Product Alert #66
Model 6603DT Drying Tube (Superseded Product)
Sealing of vent hole by sealing label gum residue
24 January 2006
Problem
The 6603DT Drying Tube has a packaging seal applied to the vent hole in the side of the tube. This is removed when the tube is installed.
We have one reported instance where a thin residual layer of adhesive from the packaging label has blocked the hole preventing pressure equalisation and hence an error in the measured pressure from the instrument.
Correction
After removing the label inspect the vent hole to ensure that is its clear and that no residual adhesive remains.
