Wiring

WARNING
• 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.
CAUTION
Precautions to be taken for power supply wiring
• When using stranded wires, make sure to use the round crimp-style
terminal for connection to the power supply terminal block.
Screw
• When connecting the inter-unit wires to the terminal block using a single core wire, be sure to curl the end of the lead.
I mproper work may cause heat and fire.
• Do not turn on the circuit breaker until all work is completed.
1) Strip the insulation from the wire (3/4 inch (20mm)).
2) Connect the inter-unit wires between the indoor and outdoor units so that the terminal numbers match. Tighten the
terminal screws securely. It is recommended that a slot-head screwdriver be used to tighten the screws.
Recommend using AWG14, stranded and
insulated wire for connections between indoor and
outdoor units.
Local code always supersedes recommendation.
NOTE
Take care to ensure that all wiring between indoor unit and outdoor unit has a consistent connection. Any splices can cause
communication errors.
