    Cooling / heating Correction Factors For the Art Cool Premier system, calculate the equivalent length of the liquid line from the outdoor unit to the indoor unit. Also, determine the elevation difference of the indoor unit above or below the outdoor unit. Find corresponding cooling or heating capacity correction factors as shown in Figure 5 and Figure 6.
