10-22-4. Indicating (marking) the indoor and outdoor unit combination number
Indicate (mark) the number after automatic address setting is completed.
(1) 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 removed to indicate the numbers in an
easily visible location on the indoor units (near the indoor unit nameplates).
Example: (Outdoor) 1 – (Indoor) 1, 2...
(Outdoor) 2 – (Indoor) 1, 2...
(2) These numbers will be needed for maintenance. Be sure to indicate them.
