SOURCE: gas pressure

It depends on the indoor and outdoor temperature and humidity. The low side pressure can be in the area of 135# to 145# with an indoor temperature of 80° and 50% relative humidity, and the outdoor pressure can be in the area of 300# to 330# on a 95° day depending on effeciency rating.
If your asking this to charge your a/c this is not how to charge your a/c.
Charging AC by superheat and subcool
First charging a unit by superheat, this is only for Acs with an orifice or capillary tube.
Optimum superheat is 12° to 15° at the compressor or suction line outside the unit.
Hook up your gages and put a thermometer on suction line (large line), start the AC. Measure the temperature of the suction line and read the pressure on your gages. Theres a temperature scale on your gages for R-22 or R-410A the needle will show you the pressure on the outer scale and if you follow it down to the R-22 or R-410a inner scale that is the saturation temperature for that refrigerant, (you can also use a temperature pressure chart), now read the thermometer, let’s say the suction temperature( the thermometer) is 67° and the saturation temperature (the gages or temp. press. Chart), is 55°, subtract the saturation temperature from the suction temperature, 67°- 55° = 12° superheat.
Charging by Subcooling, this is for Acs with a thermostatic expansion valve, it’s common to see a sight glass on the liquid line (on these units with a sight glass just clear it, when, indoor room is at approximate set point of the thermostat). Optimum sub cooling is 12° to 15° at the outdoor unit.
Hook up your gages and put a thermometer on liquid line (small line), start the AC. Measure the temperature of the liquid line and read the pressure on your gages. Theres a temperature scale on your gages for R-22 or R-410A the needle will show you the pressure on the outer scale and if you follow it down to the R-22 or R-410a inner scale that is the saturation temperature for that refrigerant,(you can also use a temperature pressure chart), now read the thermometer, let’s say the liquid temperature( the thermometer) is 100° and the saturation temperature (the gages or temp. press. Chart), is 114°, subtract the liquid temperature from the saturation temperature, 114°- 100° = 14° subcool.

SOURCE: Remove and relocate split air conditioner

The simplest way of explaining this is as per the following. On your outdoor compressor unit there should be two pipes, one smaller diameter [high pressure] and a larger diameter pipe [low pressure]. Turn your A/C on inside the house and then shut off the smaller diameter pipe. Run the unit for a around 3 to 4 minutes and then check if the cooling is reducing from the unit inside the house. When you feel room temperature air [not cool] being emitted from the indoor unit shut off the larger diameter pipe and turn off unit. Isolate electrics, disconnect A/C piping and immediately seal the piping with good quality tape to prevent egress of dirt. When re-installing a quick purge of gas is usually only required to clear the lines if they were sealed properly and kept clean. Ideally running a vacuum pump is recommended but if care was taken then it may not be needed, as in many of my installations.

Mini splits need to have the refrigerant weighed in. First, ( if the system is already empty ) pull a vacuum down to 500 microns. Second, add the amount of refrigerant listed on the mfg. tag. Hope this helps!
