Assembly the pump tubing

Pump tubing is a consumable whose working life depends on the

contact pressure. This is why when the pump is switched off for a long

time, the tubing cassette should be lifted by fully loosening spring

lever

on the right-hand side (in this way the correctly set optimal

contact pressure is retained).

The 6.1826.0X0 Pump tubing consists of PVC or PP and must

therefore not be rinsed with solvents that contain acetone. In this case

you should either use different pump tubing or use a different pump

for rinsing.
