Air conditioner questions

[Hatteras58]

I'm having the following air conditioner problems and would like to ask for some input from the HOF experts:
1. One of the salon units runs about 5 seconds and then trips the breaker (30A). This only happens in the AC mode, not the heat mode. I replaced the breaker but same problem. What should I check?
2. One of the other AC units appears to need some R-22, which I have on hand. At 80 deg F water temp, what pressure should I need on the suction side of the system? Air temp here is about 85 deg.

Thanks in advance for any help.

Thanks Beachcomber. Any chance you could attach this table in a format that I can open? It gets a bit fuzzy when I zoom.
Thanks.
