Routing the tubing
22
To position tube B in the pump heads:
1
Determine which of the two pump heads (1) will control the input flow (fill
direction) to the reservoir and which will control the output flow (empty
direction) to the waste bottle.
Each pump head can be configured in the software to flow in either
direction. In the following figure, the lower pump head controls the output
flow to the reservoir, and the upper pump head controls the input flow.
96AM Wash Station. Agilent Technologies recommends using the lower
pump for the output and the upper for the input as the figure shows.

For each pump head, cut a length of tube B that is long enough so that the
tubing can gently arch over the rollers in the pump head and still have
plenty of slack on either side of the pump head for a connection to tube A.
3
To insert tube B into a pump head:
a
Lift up the flip- top cover on the pump head so that it is fully open.
b
On each side of the pump head, turn the dial to open the clamps
(V-grooves) fully to accommodate the diameter of tube B. See the
preceding figure for the dial location (2).
c
Insert a portion of tube B so that the tubing gently arches over the
rollers. Ensure the tubing is located in the center of the tube clamps
(V-grooves) on either side of the pump head, and then carefully lower
the cover.
Repeat this step for the other pump head.
CAUTION
Ensure that the pump head clamps are set properly for the diameter of the
tubing. Incorrectly adjusted clamps can constrict the flow or damage the tubing when the
pump head is closed.
Note: If any creeping of the tubing occurs during operation, tighten the
clamps slightly using the clamp dials (2).
