CAUTION

(1)When linking outdoor units in a network (S-net link system), disconnect the terminal extended from the short plug (CN003, 2P Black, location: right bottom on the outdoor main control PCB) from all outdoor units except any one of the outdoor units. (When shipping: In shorted condition.)

Otherwise the communication of S-net link system is not performed. For a system without link (no connection wir- ing between outdoor units), do not remove the short plug.

(2)Do not install the inter-unit control wiring in a way that forms a loop. (Fig. 5-1)
