Rebuild the injection valve after about 2,100 cycles of use. Rebuild the diverter
valve after about 1,000 cycles of use. When the AS is operating under
Chromeleon control, a reminder message is displayed in the Audit Trail when the
number of cycles reaches this usage limit. If the AS is operating under front panel
control, the
USAGE LOG SCREEN (see Section C.9.6) displays the number of
cycles performed since the valve was last rebuilt.
