lamps.
Perform judgment in accordance with the following.
TEST RUNNING
When the air conditioner is run by pressing the remote control
unit test run button, the OPERATION, TIMER, and VERTICAL
SWING lamps flash slowly at the same time.

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.
