7. Test run
Step 2 Switch the remote controller to "Test run".
Select "Test run" from the Service menu, and press the [SELECT] button. (Fig. 7-1)
Select "Test run" from the Test run menu, and press the [SELECT] button. (Fig. 7-2)
The test run operation starts, and the Test run operation screen is displayed.
Step 3 Perform the test run and check the airflow temperature and auto vane.
Press the [F1] button to change the operation mode. (Fig. 7-3)
Cooling mode: Check that cool air blows from the unit.
Heating mode: Check that warm air blows from the unit.
Press the [SELECT] button to display the Vane operation screen, and then press
the [F1] and [F2] buttons to check the auto vane. (Fig. 7-4)
Press the [RETURN] button to return to the Test run operation screen.
Step 4 Confirm the operation of the outdoor unit fan.
The speed of the outdoor unit fan is controlled in order to control the performance of the unit. Depending on the ambient air, the fan will rotate at a slow speed and will keep
rotating at that speed unless the performance is insufficient. Therefore, the outdoor wind may cause the fan to stop rotating or to rotate in the opposite direction, but this is
not a problem.
Step 5 Stop the test run.
Press the [ON/OFF] button to stop the test run. (The Test run menu will appear.)
