3.6 Tube loading and
removal
Lift the flip top until fully open.
Select enough tube length for the curve of the
pump track. Place the tube between the rotor
rollers and the track, pressed against the
pumphead inner wall. The tube must not be
twisted or stretched against the rollers.
Lower the flip top until it clicks into its fully
closed position. The track closes automatically
and the tube is stretched correctly as it does
so.
To remove the tube, reverse the sequence.
Click!
Check that the tube holders on both sides of the
pumphead are correctly set for the size of tube you
are using.
Always isolate the pump from
the mains power supply before
opening the guard or
performing any positioning,
removal or maintenance
activity.
