Cleaning the FPD+ Brazement

The brazement uses an inert coating layer. Abrasives may scratch this layer. Hard scrubbing

can scratch this layer. Solutions or soaps with a pH > 8 can also damage this layer. Do not
steam clean.
The FPD+ brazement, which consists of the transfer line and emission block assemblies, uses
an inert coating layer to provide better performance. Normally, manually cleaning the
brazement is not required. However, if it becomes necessary to clean the brazement to
remove contamination, note that exposing the inert coating to abrasives or certain solvents
will degrade the coating. If cleaning is needed, follow the recommendations below for best
results:

Rinse with a solvent appropriate to dissolve the expected contaminants. Avoid abrasive or
highly basic solutions (see the caution above). Recommended solvents: dichloromethane,
acetone, or methanol.
Mildly sonicate if needed, but excessive sonication can damage the coating layer.
Gently remove solids using a soft, nylon bristle brush. Do not scrub hard. Recommended
brush: Use the MMI inlet cleaning brush from the MMI cleaning kit (G3510-80820). (Do
NOT used the MMI inlet abrasive cleaning swab, G3510-80829.)
