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.
