Restrictions and Cautions for Wiring between

Units:

Make sure to observe the restrictions below. If they are

not observed, transmission error may occur.

Maximum wiring length: 3280 ft. (1000 m)

Total wiring length: 6560 ft. (2000 m) or less

Maximum number of branches: 5

• Never connect 208-230V to the terminal block for the trans-

mission wiring.

Doing so will break the entire system.

• The transmission wiring from the indoor units must be con-

nected to the F1/F2 ( to indoor unit) terminals on the PC

board in the outdoor unit.

Only the cool/heat selector remote controller can use a tri-

axial cable.

∗ All cables used in the wiring between the units should

be procured on the site.

units. However, sub-branching from a branch is not

allowed.
