15. Examine the mixer module. Make sure that the 3 O-rings are in their circular grooves.
16. If the O-rings stay attached to the manifold when the mixer module is removed, carefully remove
the O-rings from the manifold and insert them into the circular grooves on the mixer module. Do
not use damaged O-rings. Replacement O-rings are available from Hypertherm.
17. If technical service tells you that the serial number (S/N) for the old mixer module is necessary,
look for this number on the side of the mixer-module assembly, as shown in Figure 4. If the S/N
is not necessary, continue to the next step.

18. Examine the manifold. Look for dust or debris. Use a clean, lint-free cloth to remove all
contamination. Do not use compressed air, which can push dust and debris into the manifold
openings.
