Clamping of cables
①
Arrange 2 power cables on the control panel.
②
First, fasten the steel clamp with a screw to the inner
boss of control panel.
③
For the cooling model, fix the other side of the clamp with
a screw strongly. For the heat pump model, put the
0.75mm
2
cable (thinner cable) on the clamp and tighten it
with a plastic clamp to the other boss of the control
panel.
④
In Australia, the length of power supply cord measured
from the entry of the power supply cord to the middle of
live pin on the power plug should be over 5.9ft.
3) Conduit connection
①
Remove the busing rubber product attached on the
indoor unit.
②
Set the connecting cable into the terminal block of indoor
unit, and tighten set screw to lock the conduit bracket to
the indoor unit.
③
Join the conduit and the conduit bracket together.
1. Use round crimp-style terminals for connecting
wires to the power supply terminal block. If
unavailable, observe the following points when
wiring.
• Do not connect wires of different gauge to the same power
supply terminal.
• Use the specified electric wire. Connect the wire securely
to the terminal. Lock the wire down without applying
excessive force to the terminal.
2. Tightening torque for the terminal screws.
• Use the correct screwdriver for tightening the terminal
screws. If the blade of screwdriver is too small, the
head of the screw might be damaged, and the screw
will not be properly tightened.
• If the terminal screws are tightened too hard, screws
might be damaged.
3. Do not connect wires of different gauge to the
same grounding terminal. Loose connection may
deteriorate protection.
4. Outside of the unit, keep proper separation
between transmission and power supply wiring.
The equipment may malfunction if subjected to
electrical (external) noise.
5. Never connect power supply wiring to the terminal
block for remote controller wiring. A mistake of
the sort could damage the entire system.
6. Use only specified wire and tightly connect wires
to terminals. Be careful wires do not place
external stress on terminals. Keep wiring in neat
order and so as not to obstruct other equipment
such as popping open the electric parts box
cover. Make sure the cover closes tight.
Incomplete connections could result in overheat-
ing, and in worse case, electric shock or fire.

Connect wires of the same gauge to both sides
• Make sure to attach the sealing material or (field sup-
plied) to hole of wiring to prevent the infiltration of foreign
particle from outside. Otherwise a short-circuit may
occur inside the electric parts box
• When clamping the wires, be sure no pressure is applied
to the wire connections by using the included clamping
material to make appropriate clamps. Also, when wiring,
make sure the cover on the electric parts box fits snugly
by arranging the wires neatly and attaching the electric
parts box cover firmly. When attaching the electric parts
box cover, make sure no wires get caught in the edges.
Pass wiring through the wiring through holes to prevent
damage to them.
• Make sure the remote controller wiring, the wiring
between the units, and other electrical wiring do not
pass through the same locations outside of the unit, sep-
arating them properly, otherwise electrical noise (exter-
nal static) could cause product malfunction.
CAUTION
• Make sure that the screws of the terminal are fixed
tightly.
