ERROR CONTENTS

•To stop test running, press the START/STOP button.

•For the operation method, refer to the operating manual and

perform operation check.

•Check that there are no abnormal sounds or vibration

sounds during test running.

•When EE : EE blinks at the current time display, there is an

error inside the air conditioner. If the SET TIME button ( )

and TEMP./DAY button ( ) are pressed simultaneously for

more than three seconds, the self diagnosis check will start

and the error contents will be displayed at the current time

display. When the operation lamp lights, press the

START/STOP button and after operation lamp goes off,

perform the same operation. Process the error contents by

referring to (Table 1).
