Cleaning the Tee Junction

Maintenance	6

1)Pull the axle away from the valve main body.

2)Remove the ceramic stator from the valve axle.

3)Tap the valve inner body against a clean, solid surface to remove the spring and PTFE spring cover.

4)Do not remove the inner ceramic surface from the valve main body.

5)The parts can be cleaned with a non-abrasive cloth dampened with alcohol, or by autoclaving them.

6)Dry the components using a lint-free cloth.

7)Check that the ceramic parts are dry and wait for them to cool to room temperature before reassembling the valve.

The Tee junction is a single piece. Apart from dis- mounting it from the 402, there is no disassembly procedure. The Tee junction can be cleaned or autoclaved.

1)Disconnect the inlet and outlet tubing from the Tee junction.

2)Dismount the Tee junction and syringe assembly and separate the syringe from the Tee junction.

3)Undo the two screws securing the Tee junction to the 402 front plate and remove the Tee junc- tion.

4)Autoclave the Tee junction.

5)Reinstall the Tee junction by following the instructions given in Chapter 3.
