Voltage tolerance is ±10%.
Maximum allowable voltage unbalance is 2%.
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.
RFA = Recommended Fuse Amps.
RLA = Rated Load Amps.
FLA = Full Load Amps.
Indoor Fan Motor (FLA) is based on the max. combination
of IDUs.
The maximum combination for each outdoor unit is:
- 18,000 ODU (LMU180HHV): 12,000 IDU x 2
- 24,000 ODU (LMU240HHV): 12,000 IDU x 2 + 9,000 IDU
x 1
- 30,000 ODU (LMU300HHV): 12,000 IDU x 3
