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.
Keep in mind that it will become the cause of getting drain pipe blocked if water collects on drain pipe.

GENERAL INSTRUCTIONS

• All fi eld 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" attached to the unit.
• 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 block wiring to the outdoor unit and BS unit is properly matched. If wiring and piping between the
outdoor unit and 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.
DANGER
• Do not ground units to water pipes, telephone wires or lightning rods because incomplete grounding
could cause a severe shock hazard resulting in severe injury or death, and to gas pipes because a gas
leak could result in an explosion which could lead to severe injury or death.
