Risk of injury to eyes, skin and respiratory
During the first days of system use, check the screw joint between the syringe
and valve to avoid leaks and the potential escape of reagents.
When working with chemicals and/or solvents, always observe the relevant acci-
dent prevention regulations and wear appropriate personal protective clothing for
eye, face, hand, body and/or respiratory protection.
Make sure that the tubes are never kinked.
Regularly check the system as well as all tubes and connections for
leaks, condition and cleanliness.
To prevent twisting of the tubes, you should always connect flange tube
connections before those with grommets.

1. Remove the protective stickers on the burette valve and the four
pump connections.
2. Make sure that the pre-installed white O-rings are not removed.
