De-ice boots

So. I had a g500txi, g5 and gad43e installed last fall. The long and short is I have no more electric or vaccum gyros. The vacuum pumps are now need only to run the de-ice boots. My vacuum showing. Way too high. I assume the vacuum relief/pressure valves need to be adjusted. Any help as to how? Should have the installer done this?

Do you have the Service Manual for your aircraft?

I do, was reading about setting the relief valve last night. Not too hard a process and a little less critical given no vacuum instruments. Any guidance as to where those valves are? Planes are pretty tight....

Found both relief valves. One on the engine side of firewall on front engine, one inside gear well on right side main for rear engine. Was able to get overall suction down to 6. Which is about 0.8 higher than specified, but I have no instruments in the system any longer that use it, on the boots. Any thoughts as to my risk?
