8 ERROR CONTENTS Operation can be checked by lighting and flashing of the grille display section OPERATION and TIMER lamps. Perform judgment in accordance with the following. CHECK ITEMS 1. INDOOR UNIT SWING TIMER OPERATION MANUAL AUTO (1) Is operation of each button on the remote control unit normal? (2) Does each lamp light normally? (3) Do not air flow direction louvers operate normally? (4) Is the drain normal? (5) Is there any abnormal noise and vibration during operation? SWING LAMP (Orange) TIMER LAMP (Green) OPERATION LAMP (Red) 2. OUTDOOR UNIT TEST RUNNING When the air conditioner is run by pressing the remote control unit test run button, the OPERATION and TIMER lamps flash slowly at the same time. ERROR The OPERATION, TIMER, and SWING lamps operate as follows (Table 1) according to the error contents. (1) Is there any abnormal noise and vibration during operation? (2) Will noise, wind or drain water from the unit disturb the neighbors? (3) Is there any gas leakage? Do not operate the air conditioner in the test running state for a long time.
