Electrical Data
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; Full Load Amps [A]) is based on the following indoor unit
combinations:.
- 18,000 ODU (LMU183HV): 9k Wall Mounted IDU x 2
- 24,000 ODU (LMU243HV): 7k Wall Mounted IDU x 2 + 9k Wall Mounted IDU x 1
- 30,000 ODU (LMU303HV): 9k Wall Mounted IDU x 4
- 36,000 ODU (LMU363HV): 9k Wall Mounted IDU x 4
*Wall Mounted IDU FLA is 0.2
