3. Trial Operation
Outline
1. Measure the supply voltage and make sure that it falls in the specified range.
2. Trial operation should be carried out in either cooling or heating mode.
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.
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 mode when the circuit
breaker is restored.
In cooling mode, select the lowest programmable temperature; in heating mode, select the
highest programmable temperature.
Trial operation may be disabled in either 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 mode, 20°C to 24°C in heating mode)
For protection, the system does not start for 3 minutes after it is turned off.
