It appears that the r27 manual available for download doesn't show how the multi-strainer hoses and the ac pump and strainer are connected together correctly. As a 20 year submariner I should be able to follow these simplified pipe diagrams. So, I want to flush the ac but can't get the flow quite figured out. Not shown in the manual is the hose that goes from the ac pump to the multi-strainer (or vice versa). Anybody know how to get this done on a 2019?
