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.

CITY MULTI systems could have various capacities at different design temperatures. Using the nominal cooling/heating capacity
values and the ratios below, the capacity can be found for different temperatures.
To select high heating performance mode, DipSW 7-3 must be set to ON. (In the low ambient temperature, heating capacity

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.
