• 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 harmonics must be used in order to
prevent any malfunction of the earth leak detector itself.)
• Use an all-pole disconnection type circuit breaker with at least 3mm between the contact point gaps.
• The earth leakage circuit breaker must operate at 30mA or lower.
• 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.
1) Strip the insulation from the wire (20mm).
2) Connect the inter-unit 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
block.
• When using stranded wires, make sure to use a
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.
• Use the following method when installing a round crimp-style terminal.
• Use the following method when installing a single
core wire.
Firmly fix the wires with the terminal screws.
