[DeTomaso] Simple question on Condenser fan

[Asa Jay Laughton]

Matt Wells did some road testing with yarn tufts and a camera, with  
and without the fan running.  His videos are on YouTube.

The condensor, apparently doesn't even really need the fan and yes, it  
sucks -in- toward the tub, not the other way round which you would  
think it more intuitive.  (if I recall everything correctly)

Weird, I know... go look at the videos.
