ERROR CONTENTS
1. REMOTE CONTROLLER2. OUTDOOR UNIT
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).
Stop operation.
Table 1
When the outdoor temperature drops, the outdoor unit's fans
may switch to low speed, or one of the fans may stop
intermittently.
ERROR : Heat & Cool model (Reverse cycle) only
The LED lamps operate as follows (Table 2) according to the
error contents.
The LED lamps are on the outdoor unit board.

Table 2
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 the fault is cleared, the LED lamp goes off.
However, for discharge pipe temperature abnormal and high
pressure abnormal, the LED lamp lights continuously for 24
hours, as long as the power is not turned off.
