Gas Leakage Inspection
Please use gas leakage detector to check if
leakage occurs at the connection of Flare nut
as shown on the right.
If gas leakage occurs, further tighten the
connection to stop leakage.

Installation Of Remote Controller
2
●
The remote controller can be placed in its holder which is
fi
xed on wall or beam.
●
To operate the remote controller at its holder, please ensure
that the unit can receive signal transmitted from the controller
at the place where the holder is to be
fi
xed. The unit will beep
when signal is received from the remote controller. The signal
transmission is weaken by the
fl
uorescent light. Therefore,
during the installation of the remote control holder, please
switch on the light, even during day time, to determine the
mounting location of the holder.
<
IA1128: A
>
The controller must
be hooked onto the
hook at the lower
part of the holder.
Push in the remote
controller in the
direction as shown
in
fi
gure below.
Preparation of Pipe
1
●
Use a pipe cutter to cut the copper pipe.
●
Jagged edge will cause leakage.
●
Point the side to be trimmed downwards during trimming to prevent copper
chips from entering the pipe.
●
Before
fl
aring, please put on the
fl
are nut.

WARNING
●
If you cannot attach the side cover due to the connecting
cord, press the connecting cord in direction to the front
panel to
fi
x it.
●
Be sure that the hooks of the side cover is
fi
xed in certainly.
Otherwise water penetration may occur and this causes
short circuit or faults.
●
The connecting cord should not touch to service valve and
pipes. (It becomes high temperature in heating operation.)
●
The naked part of the wire core should be 10 mm and
fi
x it to the terminal tightly. Then try to pull the
individual wire to check if the contact is tight. Improper insertion may burn the terminal.
●
Be sure to use only power cables approved from the authorities in your country. For example in Germany:
Cable type: NYM 3x1.5mm
2
, (fuse = 16A time delay)
●
Please refer to the installation manual for wire connection to the terminals of the units. The cabling must
meet the standards of electrical installation.
●
There is a AC voltage of 220V between the L and N terminals. Therefore, before servicing, be sure to
remove the plug from the AC outlet or switch off the main switch.
Checking for the electric source and the
voltage range
●
Before installation, the power source must be checked and necessary wiring
work must be completed. To make the wiring capacity proper, use the wire
gauges list below for the lead-in from a pole transformer and for the wiring from
a switch board of fuse box to the main switch and outdoor unit in consideration
of the locked rotor current.
●
Investigate the power supply capacity and other electrical
conditions at the installation location.
Depending on the model of room air conditioner to be installed,
request the customer to make arrangements for the necessary
electrical work etc.
The electrical work includes the wiring work up the outdoor. In
localities where electrical conditions are poor, use of a voltage
regulation is recommended.
IMPORTANT
●
THIS APPLIANCE MUST BE EARTHED.

How to Attach the Front Cover
1 After covering the front cover to the unit, certainly hook
at the upper portion (four places). Then, check that the
drain pan is certainly attached. Push the front cover in
the direction of arrow at the
portion of hooks.
2 Hook the front cover at lower portion to the drain pan and
then
fi
x them by screws and attach the caps.
3 Connect the wire connector,
fi
xed the screw and electrical
cover.
4 Attach the front panel.
●
Certainly insert the left shaft of the front panel to the hole
of the front cover. Next insert the right shaft as same as
the left.
5 Attach the
fi
lters which are placed the surface written
“FRONT” up.
●
After

Please use a new socket. Accident may occur due to the
use of old socket because of poor contact.
●
Please plug in and then remove the plug for 2 – 3 times.
This is to ensure that the plug is completely plugged into
the socket.
●
Keep additional length for the power cord and do not
render the plug under external force as this may cause
poor contact.
●
Do not
fi
x the power cord with U-shape nail.

Completely unscrew the spindle of the
service valve (at 2 places) in anti-clockwise
direction to allow the
fl
ow of refrigerant (using
