Press the ON/OFF button within 10 seconds to start the test run and check the operationstatus for about 3 minutes. The refrigerant pressure may not rise immediately, even if thestop valve is opened after an air purge is performed using a vacuum pump. This is becausethe indoor unit refrigerant piping is closed off with electric valves inside. This will not createany problems during operation.7. Push the air flow direction adjust button and check if the unit is responding to the new airflow direction position.8. Press the inspection/test operation button of the remote controller 2 times to go into checkmode and to make sure that the malfunction code displays “00” (=normal). In case themalfunction code does not display “00”, refer to “Failure diagnosis at the moment of firstinstallation” on page 52.9.

In order to detect stop valves failing to open, operation of the unit is compulsorily performedin cooling for 2-3 minutes during the first test run, even if the remote controller was set toheating operation. In this case, the remote controller will have kept displaying the heatingsymbol all the time and the unit will switch to heating operation automatically after elapse ofthat time.2. In case you cannot operate the unit in test run mode for any unusual reason, refer to “Failurediagnosis at the moment of first installation” on page 52.3. In case of a wireless remote controller, execute the test run only after having installed theindoor unit decoration panel with infrared receiver first.4. In case the panels of indoor units are not yet installed to the indoor units, make sure to shutoff the power supply after finishing the complete test run.5. A complete test run surely includes shutting off power after having performed a normaloperation stop on the remote controller.
