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 simultane-
ously 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 sec-
onds or more to start the self-diagnosis.
Refer to the following tables for the description of each error code.

DANGER
This part (Choke coil) generates high voltages.
Never touch this part.
SPECIAL INSTALLATION
SETTING
PUMP DOWN (Refrigerant collecting operation)
Perform the following procedures to collect the refrigerant when moving
the indoor unit or the outdoor unit.
(1) Press the push-button switch (SW2) on the circuit board once.
The LED on the circuit board starts flashing (one second ON/one se-
cond OFF). This indicates the start of PUMP DOWN operation.
When the switch is pressed while the compressor is in operation, PUMP
DOWN operation starts automatically.
When the switch is pressed while the compressor is in stop, the com-
pressor starts to operate automatically, and then move on to PUMP
DOWN operation.
(2) PUMP DOWN operation continues for about 1 minute. When PUMP
DOWN operation is completed, the compressor stops automatically.
Then close the 2-way valve and 3-way valve immediately.
(3) Turn the power off.
ERROR CONTENTS
(outdoor unit)
1. Make a TEST RUN in accordance with the in-
stallation instruction sheet for the indoor unit.
2. OUTDOOR UNIT LEDS
When a malfunction occurs in the outdoor unit, the LED on the circuit
board lights to indicate the error. Refer to the following table for the de-
scription of each error according to the LED.
