Output Tee as well as water level noted in Breaking/Dialing in Skimmer

I have a question regarding the instructions in the article on breaking and dialing in the skimmer. The article states "For in-sump models make sure the sumps water level is consistently right below the output tee on the skimmer (usually at 5.75-6” on most of our SRO skimmers)". Where is the output tee on the Classic 110SS?? The only part I see referred to as a Tee in the assembly diagram is near the base of the unit??? Is this 5.75-6" the depth the water should be that the skimmer sits in? If so, I thought the optimal level was 7-8 inches? Or is the 5.75-6" the water inside the body of the skimmer, I am hoping the later?
