1 Strip the insulation from the wire (20 mm).
2 See caution 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 to
tighten the screws.
(See figure 4)

ROOM SETTING
The priority-room setting requires initial programming during
installation. Explain the priority-room setting as described below to
the customer, and confirm whether or not the customer wants to use
priority-room setting.
Setting it in the guest and living rooms is convenient.
Priority-room setting function
The indoor unit for which priority-room setting is applied takes priority
in the following cases.
Operation mode priority
The operation mode of the indoor unit which is set for priority-room
takes precedence over operation mode of other indoor units. This
means that in case operation mode of these other indoor units is
different from the operation mode as requested in the room that is set
for priority-room, these indoor units will enter standby mode.
All wiring must be performed by an authorized electrician.
WARNING
■
Do not use tapped wires, stranded conductor wires
(see caution 1), extension cords or connections from
a star system, as they may cause overheating,
electrical shock or fire.
■
Do not use locally purchased electrical parts inside
the product and do not branch the power for the drain
pump, etc., from the terminal block. Doing this may
cause electrical shock or fire.
■
Be sure to install an earth leakage breaker. This unit
uses an inverter, which means that an earth leakage
breaker capable of handling high harmonics needs to
be used in order to prevent malfunctioning of the earth
leakage breaker itself.
■
Use an all-pole disconnection type breaker with a
contact separation of at least 3 mm inbetween all
poles.
1 Safety breaker
2 Earth leakage circuit breaker
3 Power supply
Be sure to use a dedicated power supply circuit.
NOTE
■
If the length of a connection wire is
≥
10 m,
use Ø2.5 mm wires.
■
Make sure that wiring connections of each
individual indoor unit (room A, B, ...) match
the corresponding piping connections on the
outdoor unit refrigeration ports (A, B, ...).
CAUTION
1. In case the use of stranded conductor wires is
unavoidable for one reason or another, make sure
to install round crimp-style terminals on the tip.
Place the round crimp-style terminal on the wire
up to the covered part and fasten the terminal
with the appropriate tool.
2. When connecting the connection wires to the
terminal board using a single core wire, be sure
to perform curling.
Not executing the connections properly may
cause heat and fire.
