CAUTION

Supply power to the crankcase heater for at least 12 hoursbefore 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.

Error code

(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 toperform 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.

1c, 1d, 1E, 1F errors are only for multi type.

DANGER

This part (Choke coil) generates high voltages.Never touch this part.

SPECIAL INSTALLATIONSETTINGPUMP DOWN (Refrigerant collecting operation)

Perform the following procedures to collect the refrigerant when movingthe 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, PUMPDOWN 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 PUMPDOWN operation.

(2) PUMP DOWN operation continues for about 1 minute. When PUMPDOWN 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 LEDSWhen a malfunction occurs in the outdoor unit, the LED on the circuitboard lights to indicate the error. Refer to the following table for the de-scription of each error according to the LED.
