Introduction
Expansive variety in our line-up of indoor unitsShortest route design by free branching
Combination of line and header branching is highly
flexible, allowing the shortest route possible thereby
saving on installation time and costs. Line/header
branching after header branching is only available
with TOSHIBA.

(2) When running power supplies and control wires parallel to each other, run them through separate conduits or
maintain a suitable distance between them.

This is recommended to prevent possible noise issues.
Be sure to connect an earth leakage breaker to the power supply o

Never connect 220-240V power to the control wiring terminal block

Locate wiring system
or the control and refrigerant piping system
in the same line.
Arrange the cables so that the electrical wires do not come in to contact
with high-temperature parts of the pipework ; otherwise insulation will melt
and an accident may be caused.

Shield wire
(1) The crossover wiring and central control wiring uses a 2-core non-polarity communication wire. Use 2-core shielded wire to prevent
possible noise issues. Connect the end of the shielded wires and earth(ground) at both the outdoor and indoor unit.
Where the shielded wire is connected between a central controller and a outdoor unit, only earth(ground) at one end of
the central control line.
(2) Use 2-core non-polarity wire for remote controller. (A, B terminals)
Use 2-core non-polarity wire for wiring of group control. (A, B terminals)
