The direction in which a pump is running determines the direction in which liquid will
be transported

Fig. 27 on page 41 .
The feeder wheels of the delivery pump (left-hand side) rotate anticlockwise, which
means that liquid is pumped from right to left. The right tube end must be submerged
in the storage vessel for washing liquid, the left tube end connects to the washing
trough's inlet port.
The feeder wheels of the outflow pump (right-hand side) rotate clockwise, which
means that liquid is pumped from the left to the right. The left tube end connects to
the outlet port of the washing trough, the right tube end to the waste tank or the drain
inlet.
NOTE
To perform initial starting up, place the wash trough into liquid with little surface ten-
sion. This warrants that the pipetting tips will be uniformly washed thereafter.
CAUTION
There is danger of crushing or pinching while the pump is in action.
Terminate all currently running system programs or turn system power off before you
begin work at a peristaltic pump.
