CAUTION
• Drain piping connections
Do not connect the drain piping directly to sewage pipes that
smell of ammonia. The ammonia in the sewage might enter
the indoor unit through the drain pipes and corrode the heat
exchanger.
8. ELECTRIC WIRING WORK
8-1
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 also “Wiring diagram label”
attached to the control box lid.
• 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 main switch or other means for disconnection, having a
contact separation in all poles, must be incorporated in the
fixed wiring in accordance with relevant local and national
legislation.
Note that the operation will restart automatically if the main
power supply is turned off and then turned back on again.
• 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.
