Where to pour bleach in a Rudd rheem air conditioner model number UBHC 17J11NFD to remove clog?

Bleach will not remove a clog, it is only for routine disinfecting of the drain line. For a clog blow out the line with compressed air. There should be access to do this somewhere inside at the airhandler but if not you can blow it in the opposite direction at the drain lines termination point. Or call a pro in to do it correctly.
