14. TEST RUN

Check items
(1) Is operation of each button on the remote control unit normal?
(2) Does each lamp light normally?
(3) Do air fl ow direction louvers operate normally?
(4) Is the drain normal?
(5) Do not have an abnormal noise and vibration during operation?
 Do not operate the air conditioner in test run for a long time.
[Operation method]
 For the operation method, refer to the operating manual.
 The outdoor unit, may not operate, depending on the room temperature. In this
case, keep on pressing the MANUAL AUTO button of the indoor unit for more than
10 seconds. The operation indicator lamp and timer indicator lamp will begin to fl ash
