Electric Wiring Work
7.1
General Instructions
All field supplied parts and materials, electric works must conform to local codes.
Use copper wire only.
Follow the “WIRING DIAGRAM” attached to the unit body to wire the outdoor unit and indoor
units.
All wiring must be performed by an authorized electrician.
This system consists of multiple BS units. Mark each BS unit as unit A, unit B . . . , and be sure
the terminal board wiring to the outdoor unit and indoor unit are properly matched. If wiring and
piping between the outdoor unit, BS unit and an indoor unit are mismatched, the system may
cause a malfunction.
A circuit breaker capable of shutting down the power supply to the entire system must be
installed.
Always ground wires. (In accordance with national regulations of the pertinent country.)
Do not let the ground wire come in contact with gas pipes, water pipes, lightning rods, or
telephone ground wires.
• Gas pipes: gas leaks can cause explosions and fire.
• Water pipes: cannot be grounded if hard vinyl pipes are used.
• Telephone ground wires and lightning rods: the ground potential when struck by lightning gets
extremely high.
Do not turn on the power supply (branch switches, overload interrupters) until all other work is
done.
