Air balance and heat load.
I understand small kitchen, that's OK
I understand grill heat and outside ambient air @ 95* +
Is there enough b-t-u to cool their b-u-t-t?
You may have already worked with this but did you or can you slow down the exhaust and the make up air speed? Is there an OAD on the AC unit or can you install one.
Reason... exhaust system running too fast pulls out a lot of AC air. You compensate with make up... 95* make up.... that seems to be your real problem, right?
Suggest, if you haven't already, turn off the make up air. Slow down the exhaust. Open up the OAD if you have one. Start the make up air and adjust it's speed to give the building a slightly positive air balance.
Not being there makes it tough so all I can suggest is a WAG (wild ass guess)
The front blast from the make up can be diverted up or redirected. Matters not where the air blows as long as it "makes up" the exhausted air.
You probably have already worked on all of this and I know I am not answering your real question. "Where can you find literature showing you are correct in what you are telling your customer". Unfortunately I, like some others here, don't think you are correct by telling them the hood is wrong and are steering you to balance the building pressure by reducing exhaust and make up speed and give your ac a chance to catch up.
be carefull reducing the make up air could cause the combustion air if this is not just an ice cream stall any other kit in there
just a thought
There is faith, there is hope and then there is another compressor change
