SMPS maintenance including:

SMPS maintenance including:

- Cleaning the external impactors with kimwipe and alcohol - the nozzle on the impactor (not the preimpactor) may have been installed backwards. See new procedure for proper installation.

- Cleaning the impactor at the top of the column with kimwipe and alcohol.

- Reapplicaiton of a thin layer of grease to all the impactors

- Cleaning of the DMA and all surfaces with kimwipes and alcohol. The DMA itself was very clean, and it was just the sections around the external screws that had a bit of corrosion on them. The brass connections looked reasonable, however one side (presumably the inlet) was dirty on the inside.

- Changed the excess air filter with a new one.
