Wiring

WARNING
• Do not ground units to water pipes, gas pipes, telephone wires, or lightning rods as incomplete grounding can cause a
severe shock hazard resulting in severe injury or death.
Additionally, grounding to gas pipes could cause a gas leak and potential explosion causing severe injury or death.
• Do not use tapped wires, extension cords, or starburst connections, as they may cause overheating, electric shock, or fire.
• Do not use locally purchased electrical parts inside the product. (Do not branch the power for the drain pump, etc., from the
terminal block.) Doing so may cause electric shock or fire.
• The circuit must be protected with safety devices in accordance with local and national codes, i.e. a circuit breaker.
• Use an all-pole disconnection type circuit breaker with at least 1/8 inch (3mm) between the contact point gaps.
• When carrying out wiring, take care not to pull at the conduit.
• Do not connect the power wire to the indoor unit. Doing so may cause electric shock or fire.
• Do not turn on the circuit breaker until all work is completed.
CAUTION
Precautions to be taken for power supply wiring
Recommend stranded cable for interunit wiring. Local code always supersedes recommendation.
• For stranded wires, make sure to use the round crimp-style terminal for
connection to the power supply terminal block. Place the round crimp-
style terminals on the wires up to the covered part and secure in place.
