Good customer of mine just bought a building with a schindler 3300 in it. This customer uses us for all his buildings (over 80 units). I would feel better about taking this unit on an exam/lube type of contract if I had more info on the fault codes and safety test procedures. Being a small independent I don't want to loose 80 units over this 1. If anyone is willing to share anything on these units it would be greatly appreciated.
