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.
