Wiring
WARNING
• Do not use tapped wires, extension cords, or starburst connections, as they may cause
overheating, electrical 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.
• Be sure to install an earth leak detector. (One that can handle higher harmonics.)
(This unit uses an inverter, which means that an earth leak detector capable of handling higher
harmonics must be used, in order to prevent malfunctioning of the earth leak detector itself.)
• If NOT factory installed, a main switch or other means for disconnection, having a contact
separation in all poles providing full disconnection under overvoltage category III condition,
shall be installed in the fixed wiring.
• Do not connect the power wire to the domestic hot water tank. Doing so may cause electric
shock or fire.
CAUTION
When connecting the connection wires to the terminal block using a single core wire, be sure
•
to perform curling.
Problems with the work may cause heat and fires
Good
Stripping wire at terminal block
• If the stranded wires must be used, 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.
• Do not turn ON the safety breaker until all work is completed.
1) Strip the insulation from the wire (20mm).
2) Connect the connection wires between the
domestic hot water tank and the outdoor unit 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 block.
