• Wire modifi cation
Remove insulation from wire attached to wire kit connector.
Remove insulation from fi eld supplied cable. Use crimp type insulated butt connector to
join fi eld cable and wire kit wire.
Connect the wire with connecting wire with solder.
IMPORTANT: Be sure to insulate the connection between the wires.
Field supply
Solder and insulate the connected parts.
• Connection terminals and wiring arrangement
In following fi gure, all the possible connectors are connected for description.
In actual installation, you cannot connect all the connectors at once.

7. FIELD SETTING
There are 3 methods for address setting by FIELD SETTING as follows.
Set by either of the methods.
Each setting method is described (1) to (3) below.
(1) IU AD, REF AD SW settings ............. This section (7.1. Setting the address)
(2) Remote controller settings ............... Refer to the wired or wireless remote controller
(3) Automatic address settings ............. Refer to the outdoor unit manual for detailed
Be sure to turn OFF the power before performing the fi eld setting.
7.1. Setting the address
Use an insulated screwdriver to set the dip switches.
• Remove the cover referring to the below Fig. A. Fix the cover after addressing setting.

(1) Indoor unit address
Rotary switch (IU AD × 1)...Factory setting "0"
Rotary switch (IU AD × 10)...Factory setting "0"
When connecting multiple indoor units to 1 refrigerant system, set the address at IU
AD SW as shown in the Table A.
(2) Refrigerant circuit address
Rotary switch (IU AD × 1)...Factory setting "0"
Rotary switch (IU AD × 10)...Factory setting "0"
In the case of multiple refrigerant systems, set REF AD SW as shown in the Table
A for each refrigerant system.
Set to the same refrigerant circuit address as the outdoor unit.
• If working in an environment where the wireless remote controller can be used, the
addresses can also be set using the remote controller.
• If setting the addresses using the wireless remote controller, set the indoor unit
address and refrigerant circuit address to "00".
