Watson-Marlow Alitea 114 pumpheads: operating instructions
10
To change from the large tube to the small tube setting
Switch off the pump before changing the tube holder position. Use a pointed
device such as a ball-point pen to reposition the lower tube holders
on both sides
of the pumphead.
Press down and slightly away from the front of the pumphead, as shown in the
first picture above.
Maintain the angled downward pressure and push away from the front of the
pumphead. The jaw clicks into a new position.
Release the pressure. The jaw rises into its correct alignment. If it does not
rise, repeat the procedure, being sure to maintain downward pressure until
release.
Adjust the tube holder on the other side of the pumphead in the same way.
To change from the small tube to the large tube setting
Carry out the procedure described above, but pushing towards the front of the
pumphead.
Lift the flip top until fully open.
Place the pointed device pointing
down into the small depression pic-
tured here.
Note
: The pictures on the previous page show the tube holders’ correct positions for
small and large tubing. If a tube holder is not vertical relative to the body of the
pumphead, it is wrongly positioned. Follow the instructions above to reposition it.
