Caution for electrical work

Use copper supply wires.

Cautions when Servicing

• WARNING: When the main supply is turned off, the voltage [340 V] in the main capacitor will drop to 20 V in approx. 2 minutes (input voltage: 240 V). When servicing, make sure that LED1, LED2 on the outdoor circuit board goes out, and then wait for at least 1 minute.

• Components other than the outdoor board may be faulty: Check and take corrective action, referring to the service manual.

Do not replace the outdoor board without checking.

NOTES:

1.Refer to the wiring diagrams of the indoor units for details on wiring of each indoor unit.

Self-diagnosis function

The indoor and outdoor units can be diagnosed automatically using the self-diagnosis switch

(SW1) and LED1, LED2 (LED indication) found on the multi-controller of the outdoor unit.

LED indication : Set all contacts of SW1 to OFF.

• During normal operation

• The LED indicates the drive state of the controller in the outdoor unit.

Bit 1 2 3 4 5 6 7 8

When the compressor and

SV1 are turned during cooling operation.

1 2 3 4 5 6 7 8

Indication 52C 21S4 SV1 (SV2) Always lit

• When fault requiring inspection has occurred

The LED alternately indicates the inspection code and the location of the unit in which

the fault has occurred.

7-3. Correction by Refrigerant Piping Length

CITY MULTI systems can have extended piping lengths if certain limitations are followed, but cooling/heating capacity could be reduced. Using the following correction factor by equivalent piping length shown at 7-3-1 and 7-3-2, capacity can be found. 7-3-3 shows how to obtain the equivalent piping length.
