■ XM Type (for Link Wiring)

10-27. Caution

This unit may be used in a single-type refrigerant system
where 1 outdoor unit is connected to 1 indoor unit, and
also in a system where 1 outdoor unit is connected to
multiple indoor units (maximum 4 < Double-Twin >).
● This test run explanation describes primarily the procedure
when using the wired remote controller.
● If link wiring is used, set the outdoor unit system address
to allow the combination of indoor and outdoor units to be
identified. At the same time, indicate the indoor-outdoor unit
combination number in a location where it can be checked
easily (near the indoor unit nameplates). (This number will be
required for subsequent maintenance. Refer to 10-32-2, -3, -4.)
● Request that the customer be present when the test run is
performed. At this time, explain the operation manual and
have the customer perform the actual steps.
● Be sure to pass the manuals and warranty certificate to the
customer.
● Check that the 220 – 240 V AC wiring is not connected to the
inter-unit control wiring connector terminal.
If 220 – 240 V AC is accidentally applied, the indoor or
outdoor unit control PCB fuse will blow in order to protect the
PCB. Correct the wiring connections, then disconnect the 2P
connectors (blue, OC) that are connected to the PCB, and
replace them with 2P connectors (brown, EMG). (Refer to
the figure 10-27.)
If operation is still not possible after changing the brown
connectors, cut the JP003 for the indoor unit, and cut the
JP007 for the outdoor unit.
(Be sure to turn the power OFF before performing this work.)
