Watson-Marlow 323E, 323S, 323U and 323Du User Manual 34
Select enough tube length for the curve of the pump track. Slide the tube into
the open pumphead. The tube must not be twisted or stretched against the
rollers.
Ensure the tubing locates in the centre of the tube clamps. Carefully lower the
track. Check that the tube is not crushed in the clamps or over stretched.
When using Marprene tubing
Re-tension new tube after the first 30 minutes of running. Stop the pump. Release the
flip top. Allow the tube to resettle naturally across the rollers. Re-clamp the tube. Re-
start the pump. This will correct the normal stretching that occurs with new Marprene
tube. The correct tension is essential for good tube life.
