Automatic release valve position 1

[Ribicki]

Hello everyone,

I have this situation on my sprinkler design, I need to place an automatic release valve on the system. I'm limited to place it on the crossmain end with a mechanical tee pointing upward.
Putting it on near or far main will work the best to remove most trapped air from the system possible? (Blue circles on the image).

Thanks.

Did not think it mattered


What does the manufacture install instructions say

Here is one

. AGF recommends installing Model 7900AAV near the high point of the system, at the end of branch lines, and on top of supply risers.
