When all tubes are properly connected, see Section 2.6 to readjust the Sipper and prime the
calibrator and buffer systems.
The Sipper can be damaged if it is not properly aligned or if its alignment is disturbed. If your
Sipper needs replaced, remove the screw that mounts it to the sipper arm, disconnect the tubing
and remove the Sipper. Install the new Sipper. Reconnect the Sipper ground cable and tubing to
the new Sipper. Refer to Section 2.6 to readjust the Sipper.

The Sipper Ground Cable flexes with every sample. After several thousand samples, the cable
may break. To prevent unexpected down time, replace this cable every 6 months. Extra cables
are supplied in the Preventive Maintenance Kit.
Pull the connector out of the printed circuit board on the Sipper Arm. Remove the terminal end
of the cable from under the Sipper mounting screw. Install a new cable. Refer to Section 2.6 to
readjust the Sipper.
