4.1.2 Loading of the tubing in the pumphead
W
ARNING
Always switch off the DOSE IT when loading the tubing and when
manipulating the open pumphead.
C
AUTION
Do not adjust the tubing clamps according to the scale on the pumphead
sides because the tubing will be unnecessarily squeezed and might be
damaged. Also the pumping precision will be diminished. Use instead the
adjustments described in Table 2.
2 Adjust the tubing clamps
The jagged, V-shaped tubing clamps on both sides of
the pumphead need to be adjusted and guarantee that
the tubing does not slip when the rotor turns. The tubing
clamps are set by adjusting the finger screws in such a
way as to match the diameter of the tubing.
