NOTES:

1. Since the outdoor side electric wiring may change be sure to
check the outdoor unit electric wiring for servicing.

2. Indoor and outdoor connecting wires are made with polarities, make
wiring matching terminal numbers (1, 2, 3).

3. Symbols used in wiring diagram above are,
: Connector, : Terminal (block).

[Emergency operation procedure]

1.When the indoor unit microcomputer has failed, but all other components work properly, if you set the switch(SWE,SW6)on the indoor control
board, the indoor unit will begin Emergency Operation.

2.When you activate emergency operation of the cooling or heating, you have to set the switch(SWE)and switch(SW6)on indoor controller.
SWE:ON · Indoor fan is running high speed.
SW6-1:ON · Emergency operation of cooling mode.
SW6-1,2:ON · Emergency operation of heating mode.

3.Before you activate emergency operation, check the following points:

(1) Emergency operation cannot be activated when:

· The outdoor unit malfunctions. · The indoor fan malfunctions.

(2) Emergency operation becomes continuous only by switching the power source on / off. ON / OFF on the remote control or temperature
control etc. does not function.
(3) Avoid operating for a long time when the outdoor unit begins defrosting while emergency operation of the heating is activated,
because it will start to blow cold air.
(4) Emergency cooling should be limited to 10 hours maximum (The indoor unit heat exchanger may freeze).
(5) After emergency operation has been deactivated, set the switches etc. to their original positions.

[Self-diagnosis]

1. For details on how to operate self-diagnosis with the wireless
remote control, refer to the technical manuals etc.

2. For the wired remote control : When you quickly press twice the
CHECK switch on the remote control, the unit begins self-diagnosis,
and Check Codes generated in the past appear on the display.
For Check Codes and Symptoms refer to the table.

Symptom

Cause

Wired remote controller

On the wireless remote controller with condition above, following phenomena takes place.

• No signals from the remote controller are accepted.

• Operation lamp is blinking.

• The buzzer makes a short piping sound.

PLEASE WAIT

PLEASE WAIT → Error code

Display messages do not
appear even when operation
switch is turned ON (operation
lamp does not light up).

For about 2
minutes follow­ing power-on

After about 2
minutes has
expired follow­ing power-on

• For about 2 minutes following power-on,op­eration of the remote controller is not possible
due to system start-up. (Correct operation)

•Connector for the outdoor unit’s protection
device is not connected.

•Reverse or open phase wiring for the outdoor
unit’s power terminal block

•Incorrect wiring between indoor and outdoor
units

•Remote controller wire short

Note:
Operation is not possible for about 30 seconds after cancellation of function selection. (Correct operation)

For description of each LED (LED1, 2) provided on the indoor controller, refer to the following table.

LED1 (power for microcomputer) Indicates whether control power is supplied. Make sure that this LED is

always lit.

LED2 (power for wired remote controller)

Indicates whether power is supplied to the wired remote controller.
This LED lights only in the case of the main indoor unit.
