Install the Xpress Rinse Station and Rinse Tubing
An Xpress rinse station (Figure 3-1) and associated modified tubing
arrangement is required to accommodate the design requirements of the
ASX
PRESS PLUS system. If you are connecting the ASXpress Plus system to an
ASX-500/510 autosampler with a standard rinse station installed, then you
will need to replace it with the Xpress rinse station (supplied with the upgrade
kit), and make the tubing modifications as described in this section.
The Xpress rinse station is smaller than the one provided with the
autosampler. This smaller rinse station allows the rinse solution to flow
efficiently at the high flow rate used by the ASX
PRESS PLUS system.

Removing the Existing Rinse Station
1 Verify that the autosampler is turned off and unplugged, and that no hazardous
materials are present in the rinse station or tubing.
2 Turn the rinse station ¼ turn counter-clockwise while pulling up.
3 Note how the rinse tubing is threaded underneath the autosampler.
4 Remove the tubing connecting the rinse station to the peristaltic pump.
5 Remove the tubing connecting the rinse station to the drain/waste container.
Set the rinse station and all tubing aside, as those items will not be
reinstalled. You may wish to store the rinse station in a labeled plastic bag,
in case the autosampler ever needs to be restored to its original state.
Installing the Xpress Rinse Station
1 Connect the Y-tubing assembly to the lowest fitting of the supplied Xpress
rinse station (both provided in the upgrade kit), and to the discharge ports of
the peristaltic pump.
2 Connect one end of the supplied drain tubing to the drain/overflow fitting
(highest fitting) of the rinse station.
