CAUTION
Supply power to the crankcase heater for at least 12
hours before the start of operation in winter.
(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.

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.

EX. Self-diagnosis
2005.03.09 10
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.
