I thought about the heater valve and checked and it was functioning properly.

Should open the system again and then evacutate it again for a longer time?

It is a converted system. I have noticed that the flow thru the sight glass in the dryer is white/milky looking.....is that a sigh of too much moisture?
Thanks
