CAUTION
(1) When linking the outdoor units in a network, disconnect the terminal extended from the short plug from all outdoor units

(4) If branching the inter-unit control wiring, the number of branch points should be 16 or fewer.
(Branches that are less than 1 m are not included in the total branch number.)
