That refers to Design Pressure not operating pressure.
The specs you found is what I needed to know.
I replaced the evaporator in one yesterday.
The compressor felt really hot to me,176 degrees.
According to specs it can go to 194 without issues.
It holds 2.1 ounces of R-134a.
Amp draw is normal too.
Been running 24 hours now and holding at 25 degrees on a mid level cold control setting.
Seems all is good to go.
Thanks for the manual.
