					SUCTION PRESSURE, PSIG

To Check Operating Pressures

1.Start the unit and allow the pressures to stabilize.

2.Measure the outdoor air dry bulb temperature (F) entering the condenser coil.

3.Measure the discharge and suction pressure (psig) next to the compressor.

4.Plot the outdoor dry bulb temperature and the operating suction pressure (psig) onto the chart.

5.At the point of intersection, read to the left for the discharge pressure. The measured discharge pressure should be within ± 7 psig of the graph.
