Low Side Pressure
Low side pressure = expansion valve setting.
To adjust the low side pressure, place the gauge on the
low side suction port at the compressor. With the
compressor running, turn the adjustment knob of the
automatic expansion valve clockwise to raise low side
pressure and counterclockwise to lower pressure.
