NOTES:
1. Since the outdoor side electric wiring may change, be sure to check the outdoor unit electric wiring diagram for servicing.
2. Indoor and outdoor connecting wires have poIarities, make sure to match terminal numbers (1, 2, 3) for correct wirings.
3. SymboIs used in wiring diagram above are, : Connector, : Terminal (block).
[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.
[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, you have to set the switch(SWE) and switch(SW6) on indoor controller.
SWE:ON ·Indoor fan is running at high speed.
·Drain-up machine(optional) is working.
SW6-1:ON ·Emergency operation of cooling 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) Emergency cooling should be limited to 10 hours maximum (The indoor unit heat exchanger may freeze). (4) After emergency operation has been deactivated, set the switches etc. to their original positions. (5) Movement of the vanes does not work in emergency operation, therefore you have to slowly set them manually to the appropriate position.

3 Short-cut of remote controller wires 4 Defective remote controller
1 Check the setting of main/sub for indoor
unit.
Set the main unit. Set main/sub using SW5-3 on indoor controller board.
Check indoor/outdoor unit connecting wire for connection failure.
1 Check the connection of remote con-
troller wires in case of twin triple indoor unit system. When 2 or more indoor units are wired in one refrigerant system, connect remote controller wires to one of those units.
2 Remove indoor/outdoor connecting wires
and check LED2 on indoor controller board.
• When LED2 is blinking, check the short­cut of indoor/outdoor connecting wires.
• When LED2 is lit, connect indoor/outdoor connecting wires again, and; if LED2 is blinking, outdoor unit’s controller board is defective; if LED2 is lit, connection failure of indoor/outdoor terminal block etc. has returned to normal.
34 Remove remote controller wires and
check LED2 on indoor controller board.
• When LED2 is blinking, check the short-cut of remote controller wires.
• When LED2 is lit, connect remote controller wires again and:
if LED2 is blinking, remote controller is defective; if LED2 is lit, connection failure of remote controller terminal block etc. has returned to normal.

Phenomena
After completing installation and the wiring and piping of the indoor and outdoor units, check for refrigerant leakage, looseness in the power supply or control wiring, wrong polarity, and no disconnection of 1 phase in the supply. Use a 500-volt megohmmeter to check that the resistance between the power supply terminals and ground is at least 1.0M".
Do not carry out this test on the control wiring (low voltage circuit) terminals.
Warning: Do not use the air conditioner if the insulation resistance is less than 1.0M".

7-5-1. Before test run
Countermeasure
1 Check 1 (left).
• Check the vane motor. (Refer to “How to check the parts”.)
• Check for breaking of wire or connec­tion failure of connector.
• Check “Up/down vane setting”. (Unit function selection by remote controller).
2 Normal operation (Each connector on
vane motor side is disconnected.)
1 Replace batteries of wireless remote con-
troller.
2~4
Check contact failure of each connector. If no problems are found of connector, replace indoor controller board. When the same trouble occurs even if indoor controller board is replaced, replace wire­less remote controller board.

7-5-3. When wired remote controller or indoor unit micro computer troubles
1.When the wired remote control or the indoor unit microcomputer has failed, but all other components work if you set the switch (SWE, SW6) on the indoor control board, the indoor unit will begin properly
Emergency Operation.
wNote on the wireless remote control: When the remote control does not function, it is possible to activate Emergency
Operation by using the indoor unit emergency operation switch (SW1,SW2 of the wireless signal receiver board). However, if the indoor unit microcomputer has failed, it is necessary to proceed with points 2 and 3 below as in the case of the wired remote controller.
2.When you activate emergency operation of the cooling, you have to set the switch (SWE) and switch (SW6) on the indoor controller.
SWE : ON • Indoor fan is running at high speed. • Drain-up machine is working. SW6-1 : ON • Emergency operation of cooling 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.
• when it has detected the malfunction of drain-up machine during self-diagnosing.
(2) Emergency operation becomes continuous only by switching the power source on/off. ON/OFF on the remote control or
temperature control etc,dose not function. (3) Emergency cooling should be limited to 10 hours maximum (The indoor unit heat exchanger may freeze). (4) After emergency operation has been deactivated, set the switches etc.to their original positions. (5) Movement of the vanes does not work in emergency operation, therefore you have to slowly set them manually to the
appropriate position.

• Whenever a power outage or switching of the power supply causes the power supply of an operating air conditioner to go from OFF to ON, this function will automatically restore the operation of the air conditioner to its previous operating mode. w If the power is turned from OFF to ON when the air conditioner is not in operation, the air conditioner will not automatically
be turned on. However, the timer operation will be cancelled if the air conditioner is in timer operation (including when the unit is waiting for its start time). Setting for timer operation must be performed once again.
• If there is a momentary power outage of less than 1 second while the air conditioner is in operation, there may not be a clear determination of whether or not there was a power failure. When it has been determined that there has been a power failure, recovery will take approximately 4 minutes after the power is restored. So please wait. (Once "PLEASE WAIT" has appeared on the display, a protection system will operate to prevent the unit from restarting for 3 minutes.) When it has been determined that there has been no power failure, operation will continue as is.
• Settings can be made by function selections from the remote controller.
• When there is group control, selection of all refrigerants is required.
9-6. INDIVIDUAL CONTROL OPERATION FROM A SEPARATE ROOM
• By simply centralizing the remote controllers installed in each room in a separate control room, individual control or central­ized monitoring of the air conditioners in each room can be attained.
• Air conditioner control can be performed up to a total of 500 meters away by connecting the indoor units and remote con­trollers with 0.3 to 1.25 mm22-core cable.
• If a remote controller is installed in a room and control room, refer to the section on operating with 2 remote controllers.
9-7. COMBINED REMOTE/LOCAL CONTROL
• Operation/remote controller prohibit/ stop can be controlled from a remote location by routing the remote stop/start adapter (PAC-SE55RA-E optional parts) through the relay box installed on site. When this remote control is cancelled, the local remote controller can be used for operating and stopping the air conditioner.
1. Basic system wiring
• Use the remote start/stop adapter (PAC-SE55RA-E) and connect the "Start/Stop Circuit From Remote Location" that comes from the relay box and remote/local selection switch and connect it to the CN32 connector on the printed circuit board for the indoor unit.
<Points of precaution>
1 Match the rated power supply voltage of the remote/local selection switch and relay (X2) with the power supply for the con-
troller.
2 When performing group control of multiple outdoor unit using a timer, be sure to arrange the timer so that all units do not start
at the same time. If this is not performed, all of the units will start at one time creating an overcurrent that will cause the circuit breaker to operate.
3 An on-delay system is one that includes specifications for operating a limited time when an ON signal is received and has a
temporary off timer for recovery operations.
4 Use a connecting relay when the wiring length exceeds 10 meters, such as when performing remote wiring. If this is not pro-
vided, abnormal operation will occur.

2. Examples of system applications
In any of the following examples, there is 5 to 6 seconds delay from the time the operating command is issued until the oper­ation begins. 1 This is when starting and stopping is performed by remote operation or external timer and when starting and stopping by
the remote controller is to be prohibited.
2 This is when starting and stopping are performed by remote operation or external timer and when starting and stopping by
the remote controller is to be separated.
3 This is when starting and stopping are performed by remote operation and then allowing starting or stopping by remote
control at any time.
4 This is when permitting or prohibiting operation by remote controller is performed by external circuit.
Use momentary switch for SW2. (Manual operation/automatic recover switch on time is more than 1 second.) Press SW2 (on time is more than 1 second) and operation starts. After this has been done, stopping or restarting can be done by remote controller.
If SW2 is on, operation by remote controller cannot be performed. If SW2 is off, operation by remote controller is permitted.

Service Ref. : PC-4GAKD / PC-5GAKD / PC-6GAKD
Part No. Pipe length Pipe size O.D. Connection method
Note 1. How to connect refrigerant pipes
Factory supplied optional refrigerant pipings contain refrigerant at the above atmospheric pressures. As long as con­nection takes no more than 5 minutes, no air will enter, and there will be no need for air purging. Remove the blind caps and make the connections within 5 minutes. After the connections for the indoor and outdoor units are made, open the stop valve on the outdoor unit to allow refrigerant gas to flow. If piping length exceeds 20m, an additional charge of refrigerant is needed.
Note 2. The following main parts are contained in the optional refrigerant piping kit.
Heat insulating cover, vinyl tapes, joints, sleeve and flange (for wall hole).
