The low-side should be near 30 PSI at 90 degrees Fahrenheit or less. Pressure that is too much lower or higher shows there is a problem. On a properly working system, high - side pressure will be about twice the ambient temperature, plus 50 PSI.Not much more to add, really. 0 PSI on R-12 is about -21 degrees. Depending on your target temperature, you will be very close to, if not below atmospheric on the low side. If you had to put more than half the charge in it, you probably have an obstruction at the metering device.
