1. Switch the dilution flow controller to the dilution conveyor after the press to
AUTOMATIC from CASCADE mode.
2. Flush the press as follows:
- Switch the consistency controller to MANUAL and open it 100%.
- Close the HC valve on the suction of the press feed pump.
- Close the press feed valves one at time. Reduce the flow to the press to match the
trim dilution flows. This will reduce valve and pump cavitation problems.
- The torque controller for the press must turn in manual mode with the output at 70%.
- Wait for 3-4 minutes for press flushing, watching the torque, vat pressures, and
motor load on the shredder conveyor to indicate when the pulp has been flushed.
- Close the press feed valves.
