Re: Need info please
- Thanks Tony.
Just doing my bit for the forum. You guys helped me big time when I
came in :-)
This did confuse me as well when I was looking at still pictures when
I started out. Most pictures dont show it (a top view) but the top
part of the condenser is "open". What is condensed trickles down to
be collected, but the rest goes to the atmostphere.
