WARNING
• Do not use tapped wires, stranded wires (CAUTION 1)), extension cords, or starburst connections, as they may cause over-
heating, 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 leakage breaker. (One that can handle higher harmonics.)
(This unit uses an inverter, which means that it must be used an earth leakage breaker capable handling harmonics in order to
prevent malfunctioning of the earth leakage breaker 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 fire.
• Do not turn on the safety breaker until all work is completed.
1) Strip the insulation from the wire (20mm).
2) Connect the inter-unit wires between the indoor and out-
door 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.
CAUTION
• When connecting the inter-unit wire to the terminal block using
a single core wire, be sure to perform curling.
Problems with the work may cause heat and fires.
• 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.
3) Pull the wire and make sure that it does not disconnect. Then fix the wire in place with a wire retainer.
Wire retainer
Use the
specified wire
type and
connect it
securely.
Make sure the electrical
wiring does not come into
contact with the gas piping.
Refer to the figure.
Make sure connecting the
piping and connecting
wiring fit into
.
(Incorrect handling will
make it hard to attach the
stop valve cover, causing
deformation.)

Firmly secure wire retainer
so wire terminations will not
receive external stress.
Also use the two screws
located at the bottom of
the packing case to tighten
the four locations.
Be sure to clamp the wire for
power source on this location.
