GENERAL INSTRUCTIONS
• All field supplied parts and materials and electric works must
conform to local codes.
• Use copper wire only.
• For electric wiring work, refer to WIRING DIAGRAM attached
to the control box cover.
• For remote controller wiring details, refer to the installation
manual attached to the remote controller.
• 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 ground fault circuit interrupter 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 ground fault circuit interrupter and
switch, and wiring instructions.
• Be sure to ground the air conditioner.
• Do not connect the ground wiring to gas and water pipes,
lightning 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.
