What are the working pressures supposed to be for my '82 Dealer A/C? And what is the High Side Switch in the filter/dryer set to cut the compressor off at?

Thanks!

Reinstalled the A/C this week. When I got the car the compressor made noise and the system was empty. Year and a half later now that I have access to the proper tools and machines to setup the system. So I hooked everything up with new o-rings and tested for leaks. So far she blows cold! I'll give it a few weeks and put in a new expansion valve and filter/dryer. Also put on an Izuzu Diesel Alternator. It's huge! LOL Gotta drill out the dual pulley and put that back on.

Here's some pics.

 

No one knows?

Item 10 lists the pressures for high and low sides. Pressures are very dependent of the outside temp where you are charging it.
