4 Operation and maintenance
4.1 Replacing the pump tubing
Pieces of pump tubing inserted into the peristaltic pump are consumables
with a limited service life.
Pieces of pump tubing with 3 stoppers are tensioned in the tubing car-
tridge so that they end up positioned between two stoppers. This results
in two possible positions for the tubing cartridge. Once the pump tubing
exhibits significant signs of wear, it can be tensioned a second time in the
other respective position.
Maintenance interval Replace the pump tubing every 2 months.
Replace the pump tubing every 4 weeks if the peristaltic pump is being
used continuously.
