To clean the valve, complete the following steps:
1 Turn off and unplug the ASXPRESS PLUS Rapid Sample Introduction System.
2 Remove all tubing and connectors from the 6-port valve.
3 Use the hex key wrench provided to remove the three screws on the front of
the 6-port valve
Do not remove the valve body from the actuator as it will lose its position
and will require retraining if removed. Valve retraining will be discussed in
detail on page 121.
4 Note the orientation of valve body components prior to removal.
5 Gently remove the stator of the valve.
6 Use a clean-room wiper to gently clean the channels and surfaces of the stator
and rotor of any debris.
7 Use low-pressure, canned clean air to blow the channels and ports free of any
remaining debris.
8 Very carefully replace the stator of the valve, in the proper orientation noted in
step 4, and tighten the three screws to set firmly in place.
9 Reinstall all tubing and check for leaks using the Xpress Configuration Tool to
“Manual Cycle” the ASX
PRESS PLUS system as described on page 120.
