Outline 1. Measure the supply voltage and make sure that it falls within the specified range.

functions and parts, such as flap movement, are working properly.
 The air conditioner requires a small amount of power in standby mode. If the system is not to
be used for some time after installation, shut off the circuit breaker to eliminate unnecessary
power consumption.
 If the circuit breaker trips to shut off the power to the air conditioner, the system backs up the
operation mode. The system then restarts operation with the previous operation mode when
the circuit breaker is restored.
In cooling operation, select the lowest programmable temperature; in heating operation, select
the highest programmable temperature.
 Trial operation may be disabled in either operation mode depending on the room
temperature.
 After trial operation is complete, set the temperature to a normal level.
(26°C to 28°C in cooling operation, 20°C to 24°C in heating operation)
 For protection, the system does not start for 3 minutes after it is turned off.
