SAFETY PRECAUTIONS
Stopping only the indoor unit is extremely dangerous because the engine may suddenly start if the customer
operates the remote controller on the indoor unit. When working on internal parts of the outdoor unit, make
sure to cut the power to the outdoor unit at the circuit breaker before starting work. (However, if a centralized
control device such as an intelligent controller is used, a communications error may occur.) Otherwise,
perform a “Stop” operation on the outdoor unit.
