  3. Connect a new tubing connector to the new seal wash pump inlet line. Cut tubing to required length, if applicable.

  4. Connect the new seal wash pump inlet line to the seal wash outlet on the metering device head.

  5. Connect the seal wash pump inlet line to the peristaltic tubing on the seal wash pump.

Restarting the Seal Wash System

  1. Retighten the reservoir cap hand-tight. The retaining guide must remain in the hole in the reservoir cap. If it does not, press the retaining guide into the hole so that the tubing is kept in place in the cap.

  1. Check the wash lines over the entire flow path:

  1. Make sure that no bending (kink), pinching or squeezing of the wash lines is present at any point in the flow path.
  2. If you have to cut tubing to length, use a tubing cutter. Make sure that the cut is at right angle to the length of the line.

  1. Flush the seal wash system. Run the script: B01 - Change Liquids / Solvents (with: Rear Seal Wash Liquid and Refresh Only = Off.)
