12. TEST RUNS

〈 WARNING 〉
• Never perform a test run with the discharge piping thermistor (R2T) and suction piping thermistor (R3T)
removed, as this might break the compressor.
• If the technician must leave the outdoor unit for some reason, switch places with another installation
technician or close the front panel.
• Do not touch the drain pump or fan during test runs without the decoration panel installed on the indoor unit.
(Doing so could result in an electric shock or other injury.)
12-1 HOW TO TEST OPERATION
After the indoor and outdoor unit installation, be sure to perform the test operation in accordance with the
following procedure.
1. Open the front panel and check that the liquid and gas sides of the stop valves are open.
<Be sure to close the front panel before the operation (Risk of electric shock)>
Note: After doing an air-purge with a vacuum pump, the refrigerant pressure may not rise even if the stop
valves are opened.
This is because the refrigerant piping path is closed off by the outdoor unit electronic expansion
valve, etc. There are no problems if the unit is run.
2. Turn the power on at least 6 hours before operating the unit to protect the compressor.
3. Set to cooling operation with the remote controller.
4. Push the remote controller's INSPECTION/TEST OPERATION button four times (twice on the wireless
remote controller) to enter test run mode.
Within 10 seconds, press the RUN/STOP button to start the test run. Check the unit, letting it run at least
3 minutes.
Note: In the first operation after installation, the COOL operation is performed for approx. 3 minutes even
when the HEAT operation is set. After that, the operation will be switched to the HEAT operation, but
this is normal. (The remote controller displays "HEAT operation".)
Note: When the outside temperature is 24°C or more, the HEAT operation is not performed even if it is set,
but this is normal.
5. Push INSPECTION/TEST OPERATION button and operate normally.
6. Confirm function of unit according to the operation manual.
7. If the decoration panel on the indoor unit has not been installed, turn off the power after the test run.
