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).
