(1) Stop the air conditioner operation.
(2) Press the master control button and the fan control button si-
multaneously for 2 seconds or more to start the test run.
(3) Press the start/stop button to stop the test run.
[SELF-DIAGNOSIS]
When the error indication "E:EE" is displayed, follow the following
items to perform the self-diagnosis. "E:EE" indicates an error has
occurred.
1. REMOTE CONTROLLER DISPLAY
(1) Stop the air conditioner operation.
(2) Press the set temperature buttons simultaneously for 5
seconds or more to start the self-diagnosis.
Refer to the following tables for the description of each error
code.

2. OUTDOOR UNIT LEDS
Heat & Cool model (reverse cycle) only
When a malfunction occurs in the out-
door unit, the LEDs on the circuit board
light to indicate the error. Refer to the
following table for the description of
each error according to the LEDs.
LED1 LED2 Error contents
When the fault is cleared, the LED lamp goes off.
However, for discharge pipe temperature abnormal and high pres-
sure abnormal, the LED lamp lights continuously for 24 hours, as
long as the power is not turned off.
