2-9. Indicating (marking) the indoor and outdoor unit combination number
Indicate (mark) the number after auto address setting is completed.

So that the combination of each indoor unit can be easily checked when multiple units are installed, ensure that the indoor and
outdoor unit numbers correspond to the system address number on the outdoor unit control PCB, and use a magic marker or similar
means which cannot be easily erased to indicate the numbers in an easily visible location on the indoor units (near the indoor unit
nameplates).
Example: (Outdoor) 1 - (Indoor) 1
(Outdoor) 2 - (Indoor) 1
●
These numbers will be needed for maintenance.
Be sure to indicate them.
Use the remote controller to check the indoor unit address.
