To replace a reagent without mixing the new reagent with the previous one, or when shutting down the system, remove the reagent using the procedure described below.
Ensure that the reactor and converter are sufficiently dry before performing this procedure.

 

1 Drying Reactor/Convertor
  NOTE: This procedure isn’t necessary when Reactor/Convertor are drying enough.
  1) Click [Control Sequencer] and [Function Operation] on the [Maintenance] menu in the [PPSQ Analysis] window.
    

  2) Select [Dry Reactor(H)] on the [Reactor] side to remove R1, R2, R3, S2, or S3.
  3) Click [Execute]. Drying the reactor starts.
  4) Select [Bubble Conv..(H)] on the [Convertor] side to remove R4 or S4B.
  5) Click [Execute]. Drying the convertor starts.
  6) After drying for approximately 3 minutes, click [Inactive] for [Reactor] and [Convertor], respectively.

3. Removing the Reagent Inside the System
  NOTE: Be sure to remove the reagent bottle before removing the reagent inside the system.
  1) Insert the end of the tube that was inside the bottle of the reagent to be removed in a suitable container.
  2) Click [Control Sequencer] and [Function Operation] on the [Maintenance] menu in the [PPSQ Analysis] window. [Function Operation] dialog box is displayed.

    

  3) Select [Backflash ”reagent name”] on the [Reactor] side for R1, R2, R3, S2, or S3.
    And select [Backflush ”reagent name”] on the [Converter] side for R4 and S4B.
  4) [Click [Execute]. Purging the reagent inside the System starts.
    CAUTION: The reagent is pushed back with considerable force. Exercise due care.
  5) After drying for approximately 5 minutes, click [Inactive]. The function of the backflush stops.
