Problem innotec SNF 2009-02-20 00:33:35: Planetary Noise

You need to be more specific on what kind of sound. At this 
time I can NOT hear any abnormal sounds. Sometimes
air is trying to move through the bell jar and will make a noise
like rattling. This noise is OK. Jim and I listened to the 
planetary rotating under vacuum and when the system was 
vented. Still nothing abnormal. OK to use system.
