WARNING
Do not use tapped wires, stranded wires, extension cords, or starburst connections, as they may cause overheating, electrical shock, or
fi
re.
•
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
fi
re.
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.)
Use an all-pole disconnection type breaker with at least 3mm between the contact point gaps.
•
Do not connect the power wire to the indoor unit. Doing so may cause electric shock or
fi
re.
•
Do not turn on the safety breaker until all work is
•
completed.
Strip the insulation from the wire (20mm).
1)
Connect the connection wires between the indoor and
