4.1 RA Indoor Unit
Outline 1. Measure the power supply voltage and make sure that it falls in the specified range.
2. Trial operation should be carried out in either cooling or heating operation.
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 ~ 28°C in cooling, 20°C ~ 24°C in heating)
For protection, the system does not start for 3 minutes after it is turned off.
3. Carry out the trial operation in accordance with the operation manual to ensure that all
functions and parts, such as flap movement, are working properly.
Note: The air conditioner requires a small amount of power in its 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.
