WARNING
1) Do not use spliced wires, stranded wires, extension cords, or starburst connections, as they may cause
overheating, electrical shock, or fire. Follow all Local, and State electrical codes.
2) Do not use locally purchased electrical parts inside the product. (Do not overload the circuit by adding
drain pump or other electrical equipment to unit terminals.) Doing so may cause electric shock or fire.
3) Be sure to install an earth leak detector. (One that can handle higher harmonics.)
(This unit uses an inverter, which means that it must be used an earth leak detector capable handling
harmonics in order to prevent malfunctioning of the earth leak detector itself.)
4) When carrying out wiring connection, take care not to pull at the conduit.
5) Do not connect the power wire to the indoor unit. Doing so may cause electric shock or fire.
• Do not turn ON the safety breaker until all work is completed.
1)
Strip the insulation from the wire (3/4 inch).
2)
Connect the connection wires between the
indoor and outdoor units so that the terminal
numbers match. Tighten the terminal screws
securely. We recommend a flathead screwdriver
be used to tighten the screws.
The screws are packed with the terminal board.
Use the specified wire type and
connect it securely.
Observe the notes mentioned below when wiring to the power
supply terminal board.
Precautions to be taken for power supply wiring.
(Use a round crimp-style terminal for connection to the power
supply terminal board. In case it cannot be used due to
unavoidable reasons, be sure to observe the following instruction.)
CAUTION
When connecting the connection wires to the terminal board using a single core wire, be sure to perform curling.
Problems with the work may cause heat and fires.
3)
Pull the wire and make sure that it is tight. Then fix the wire in place with a strain relief.
