4.3.3 Removing Flat Panel
In order to connect the refrigerant piping,
wiring and to check drain water flow, removing
the flat panel is needed. Perform these work
according to the following instructions. Pay
attention to the resin components not to scratch.
(1) Hold both sides of the flat panel and open it,
and pull the right arm toward the inner side.
Slightly close the flat panel and pull it, then
remove the flat panel.

Turn OFF the main power switches to the
indoor unit and outdoor unit before
electrical wiring or periodical check, and
wait for at least 10 minutes.
Check to ensure the indoor and outdoor
fans have stopped before electrical wiring
or periodical check.
Protect the wires, drain pipes, electrical
parts, etc. from rats or other small animals.
If not protected, rats may gnaw at
unprotected parts, which may lead to a fire.
Avoid the contact of wires with the
refrigerant piping, sheet metal edges and
electrical components in unit. Otherwise,
the wires may get damaged or even cause
a fire.
Use ELB(earth leakage breaker) with
medium sensing rate (ELB with action time
being equal to 0.1 seconds or less). Failing
to do so may result in electric shock or a
fire.
The wires must be firmly secured. External
force applied to terminals may cause a fire.
It is forbidden to connect a plurality of
power lines into one power terminal block.
At the indoor unit side of air conditioner,
power wiring can be extended through a
power distribution box. Be sure to calculate
the wiring capacity carefully, since
excessively low wiring capacity may
frequently cause fire.
Do not start the system before all check
points are thoroughly checked.

7.1 General Check
(1) Make sure that the field-supplied electrical
components (main power switches, circuit breakers,
wires, conduit connectors and wire terminals) have
been properly selected according to the electrical
datagiven in “Technical CatalogⅠ” . Make sure that
thecomponents comply with National Electrical Code
(NEC).
(2) Use shielded twist pair cable for transmission
wiring between outdoor unit and indoor unit, remote
controller wiring between indoor units and remote
control switch.
(3) Check to ensure that the power supply voltage is
within ±10% of the rated voltage.
(4) Check the capacity of the electrical wires.
If the power source capacity is too low, the system
cannot be started due to the voltage drop.
(5) Check to ensure that the earth wire is connected.
(6) Power Source Main Switch.
Install a multi-pole main switch with a space of94
(5) or more between each phase.
7.27.2 Electrical W
iring Connection
The electrical wiring connection for the indoor unit
is shown in Fig. 7.1.
(1) Unscrew and remove the conduit mount plate
from the machine base. Fix a conduit for power
supply wiring to the plate with a lock nut and reattach
them at original position.
(2) Connect the wires of an optional remote control
switch to A, B terminals of the terminal board inside
the electrical box through the connecting hole in the
cabinet.
(3) Connect the wires between the indoor unit and
the outdoor unit to1, 2terminals of the terminal
boardinside the electrical box through the
connecting holein the cabinet.
(4) Connect power supply wires to L1, L2 and
connect earth wire to the earth. Please connect to the
power circuit with a ELB.
(5) Check to ensure that the terminal specification is
applied to the screw (M3.5 for power supply and
operating line) of the terminal box.
(6) Fix all the wires securely with cord clamp.
