There's high side pressure and low side pressure. I don't have the specs but you must get them before something gives.
A set of A/C gauges is a must so you can tell if the condenser, compressor are working properly or if you have a contaminated system or worse, a restricted system.
Pressure is measured normaly at 70 deg. ambient temperature and from there it is compensated for variations plus or minus.
Make sure the fan is turning ON and not allowing the pressure to rise too high on the high side.
