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 piping and corrode
the heat exchanger.
Keep in mind that it will block the drain pipe and cause
water to collect.
7. ELECTRIC WIRING WORK
7-1 GENERAL INSTRUCTIONS
• All 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 details of remote controller wiring, refer to the installa-
tion manual attached to the remote controller.
• All wiring must be performed by an authorized electrician.
• 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
