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.
