Note
1. Use copper cables only and ensure that all connections are solid while wiring.
2. Make sure that the power voltage matches the voltage specified on the unit nameplate.
3. Install a disconnect switch before the power input of the indoor unit to isolate the unit for maintenance. Connect the power
cable to the disconnect switch and then to the unit.
4. Cut off the power to the unit before maintenance inside the unit because the unit contains high voltage.
