8. Test run
Step 4 Confi rm 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 insuffi cient. 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.
1 Press the [ON/OFF] button to stop the test run. (The Test run menu will appear.)
Note: If an error is displayed on the remote controller, see the table below.
