Elevation Correction Factors - LG Multi V 5 Data Manual

Elevation Correction Factors

For each outdoor unit, calculate the equivalent length of the liquid line from the outdoor unit to the farthest indoor unit. Also, determine the
elevation difference of farthest indoor unit above or below the outdoor unit. Find corresponding cooling capacity correction factor in tables
below and on the next page. Multiply the cooling correction factor by standard cooling capacity. The resultant is the NET cooling capacity.
Repeat for heating correction factor.
The correction factors shown below are calculated in the LATS software programs.

1 ELF = Equivalent Pipe Length in Feet—Sum of the actual pipe length plus allocations for pressure drop through elbows, valves, and other fittings in equivalent length.
Heating Correction Factor for 072BTE5 / 072DTE5 to 336BTE5 / 336DTE5 models is 1.0 for all equivalent lengths and elevation differences.
