• For electric wiring work, refer to also “Wiring diagram”
attached to the control box lid.
• For remote controller wiring details, refer to the installation

• All wiring must be performed by an authorized electrician.
• This system consists of multiple indoor units. Mark each
indoor unit as unit A, unit B..., and be sure the terminal board
wiring to the outdoor unit and BS unit are properly matched.
If wiring and piping between the outdoor unit and an indoor
unit are mismatched, the system may cause a malfunction.
• A circuit breaker capable of shutting down power supply to
the entire system must be installed.

• Water pipes : no grounding effect if hard vinyl piping is
used.
• Telephone ground wires or lightning rods : might cause
abnormally high electric potential in the ground during
lighting storms.
