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.
