16.1 DISASSEMBLY OF THE CROSSPIECE
For disassembling of the crosspiece, the heating of the heated dilution unit should be switched off so
that the unit can cool down.
Figure 13 shows the explosion drawing of the dilution crosspiece.

We recommend to proceed according to the following steps:

Remove the insulation cover of the dilution unit, if applicable;

Remove all tube connectors on the dilution crosspiece. These are:

- Depression manometer nut 6

- Dilution gas inlet nut 4

- Sample gas outlet nut 5

- Removal of nut 1.

Nut 2 must only be removed after having disassembled the dilution
cross. Disregard may lead to destruction of the critical orifice!

Now, the dilution crosspiece is accessible for further maintenance and repair work.
