While researching the problem with the 600 series heats that Chemetronics makes(not to be consfuced with Chemtronics) i came across this recall for there series 400 units back in1997 i do not ever recall any publicity on this problem I will be meeting with a cpsc rep tomorrow to show him units I am having problems with .Thought you all should be aware of this other recall I know many of them are still in use in home systems.
