Cooling / Heating Correction Factors
For Single Zone Mega Wall Mounted systems, 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 correc-
tion factors as shown below. Multiply the correction factors by the cooling or heating capacity obtained from the capacity tables using design
conditions. The resultant is the NET cooling or heating capacity.

Altitude Correction Factor
The impact of air density must be considered on systems installed at a significant altitude above sea level, therefore, locally accepted alti-
tude correction factors using ASHRAE guidelines must be applied.
