CAUTION
• When connecting drain piping, 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 if water collects on the drain pipe it will become blocked.
7. ELECTRIC WIRING WORK
7-1 GENERAL INSTRUCTIONS
• All field supplied parts and materials and electric works must conform to local codes.
• Use copper wire only.
• For electrical wiring work, refer to the 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 so forth, and be sure the
terminal block wiring to the outdoor unit and BS unit is properly matched. If controls wiring and piping between the
outdoor and indoor units are mismatched, a communications malfunction is likely.
• 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.
