Wiring Precautions

1. EACH unit should be installed with its own dedicated power supply source. The power source
needs to be sized correctly for the unit capacity.
2. The rated voltage of the unit is as shown in this manual.
3. Before turning on, verify that the voltage is within the 187~252 V range (for 208/230 V, single
phase units).
4. Always use a grounded terminal and install a separate receptacle to supply power to the
air conditioner. For high voltage connections, fl exible electrical conduit is recommended
whenever vibration transmission may create a noise problem within the structure.
5. Use a dedicated breaker and receptacle matched to the capacity of the air conditioner.
