(6.2744.180) at the pump tubing outlet:

– Push the locknut onto the pump tubing.
– Push the appropriate adapter onto the pump tubing.
– Place the tubing olive with the filter holder into the pump

tubing so that the pump tubing is firmly in place; push the
end of the pump tubing over at least the second notch of
the olive.

– Tighten it using the union nut.

2 Removing the tubing cartridge

Press in the tubing cartridge's snap-action lever.

Tilt the tubing cartridge upwards.

Unhook the tubing cartridge from the mounting bolt.

3 Inserting the pump tubing

Press the tubing cartridge's contact pressure lever down all the
way.

Place the pump tubing in the tubing cartridge. Fit the tubing car-
tridge between two stoppers. The stoppers must snap into the
corresponding holder of the tubing cartridge.

4 Inserting the tubing cartridge

Hang the tubing cartridge in the mounting bolt and press it in the
cartridge holder until you hear the snap-action lever snap in.

Setting the flow rate
The flow rate of the peristaltic pump depends on many factors:

The inner diameter of the pump tubing

The rotational speed of the drive

The contact pressure of the tubing cartridge

NOTE

Pieces of pump tubing are consumables. The lifetime of the pump tub-
ing depends on the contact pressure, among other factors.
