• 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.
• Refer to the installation manual attached to the outdoor unit
for the size of power supply wiring connected to the outdoor
unit, the capacity of the circuit breaker and switch, and wiring
instructions.
• Be sure to ground the air conditioner.
• Do not connect the ground wire to gas and water pipes, light-
ning rods, or telephone ground wires.
• Gas pipes
:
might
cause explosions or fire if gas leaks.
• 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.

Power supply wiring
Hold the electric parts box lid and loosen the anchoring
screws (2 pc.), then remove the electric parts box lid. Align
the phase and connect the wire to the power terminal block
(6P) inside the electric parts box. After connecting, use the
included clamps (4) to bind the wire, together with the ground
wire, to the anchor.
