These charts are easily used by reading the ambient temperature along the bottom axis of the chart and then reading
the appropriate pressure curve to determine the corresponding dew-point temperature on the left axis of the chart.
The compressor discharge temperature must be maintained at a minimum of
10° F above this dew-point temperature
to prevent condensation accumulation in the lubricant reservoir. These charts assume 100% relative humidity.
