CAUTION
(1) When linking outdoor units in a network (S-
net link system), remove the short plug

the outdoor control PCB) from all outdoor
units except any one of the outdoor units.
Otherwise the communication of S-net link
system does not perform.
For a system without link (no connection
wiring between outdoor units), do not remove
the short plug.
(2) Do not install the inter-unit control wiring in a
loop. (Fig. 5-1)
