Product Recall Information

In January, 2013, we issued a product safety recall on all Dynasys APUs installed to date. The initial recall notice asked that customers discontinue all use of their Dynasys APUs until a repair solution was available.  A solution was made available beginning in February, 2013 and DynasysAPUs currently being sold are not subject to the recall.  Links to the two most recent communications to owners are as follows:
