Test Run and Final Check

1.

Trial operation and testing.

1-1 Measure the supply voltage and make sure that it falls in the specified range.

1-2 Trial operation should be carried out in either cooling or heating mode.

• In cooling mode, select the lowest programmable temperature; in heating mode, select the highest programmable temper-

ature.

1) Trial operation may be disabled in either mode depending on the room temperature.
2) 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).

3) For protection, the system disables restart operation for 3 minutes after it is turned off.

1-3 Carry out the test operation in accordance with the operation manual to ensure that all functions and parts, 

such as louver 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 will restore the original operation 

mode when the circuit breaker is opened again.
