Changing the Syringe Piston Assembly

For all syringe sizes, it is necessary to replace the piston assembly after approximately 30 000 cycles (using water).

The correct reference piston kit must be ordered:

Replacing the Piston

1)Dismount the Syringe assembly from the instru- ment, as described page 3-9.

2)Pull the piston out of the syringe body.

3)Reassemble the syringe and piston as described page 6-7.

4)Remount the syringe assembly on the valve or Tee junction.
