Voltage tolerance is ±10%.
Maximum allowable voltage unbalance is 2%.
RLA = Rated Load Amps.
MCA = Minimum Circuit Ampacity.
Maximum Overcurrent Protection (MOP) is calculated as
follows: (Largest motor FLA x 2.25) + (Sum of other motor
FLA) rounded down to the nearest standard fuse size.
Indoor Fan Motor (FLA) is based on the maximum combina-
tion of indoor units.
The max combination for each outdoor unit is:
- 18,000 ODU (LMU18CHV): 12,000 IDU x 2
- 24,000 ODU (LMU24CHV): 12,000 IDU x 2 + 9,000 IDU
x 1
- 30,000 ODU (LMU30CHV): 12,000 IDU x 3
- 36,000 ODU (LMU36CHV): 12,000 IDU x 4
