* When using R407C, the factor above is to be used when matching to condensing units with Dew Point ratings. This factor will ensure that proper
system balancing will occur to compensate for glide to t the application. If the system is sized correctly, one may expect a slight increase in system
capacity, along with slightly higher saturated suction temperatures.
